Моторные масла
Указания по моторным маслам
Примечание:
Использование моторных масел другой степени качества, кроме степени качества, предписанного в данном «Руководстве по эксплуатации», не допускается.
Качество моторных масел имеет решающее значение для работоспособности и срока службы двигателя. На основе сложных и дорогостоящих испытаний «Мерседес-Бенц» постоянно производит выдачу сертификатов допуска для моторных масел в соответствии с новейшим уровнем техники.
Для автомобилей BlueTec®6 используйте только моторные масла, соответствующие «Предписаниям «Мерседес-Бенц» по эксплуатационным материалам» согласно листу №228.51 или 228.31.
Для автомобилей BlueTec®6 с пакетом Fuel Efficiency Package (FE1) используйте моторные масла согласно листу №228.61, 228.51 или 228.31.
Для всех других автомобилей Вы можете использовать моторные масла согласно листу №228.5, 228.51, 228.3 или 228.31. Используйте преимущественно моторные масла согласно листу №228.5 или 228.3.
Моторные масла согласно листу №228.51 отличаются высоким качеством и благоприятно сказываются на:
— длительности интервала замены масла,
— параметрах износа двигателя,
— расходе топлива,
— выбросах отработавших газов.
Примечание:
На емкости для масла Вы найдете степень качества, например лист №228.51, и вязкость, например предписанный по SAE класс 5W-30.
Области применения
Всесезонные моторные масла согласно листам №228.51 или 228.31 можно использовать круглый год.
В зависимости от качества топлива (серосодержание или топливо FAME (метилэфир жирной кислоты)) интервалы замены масла сокращаются.
Замена масла
Примечание:
— При смешивании моторных масел различного качества интервалы замены моторного масла по сравнению с моторными маслами одинакового качества сокращаются. По этой причине смешивайте моторные масла различного качества только в исключительных случаях.
— Если залитое моторное масло предписанного по SAE класса (вязкости) не подходит для продолжительных низких температур наружного воздуха ниже -20 ºС, то это может привести к повреждению двигателя. Указания температуры предписанного по SAE класса относятся к свежим маслам. При эксплуатации автомобиля моторное масло стареет из-за попадания в него сажи и топливных осадков. В результате свойства моторного масла значительно ухудшаются, особенно при низкой температуре наружного воздуха. «Мерседес-Бенц» настоятельно рекомендует Вам при температуре наружного воздуха ниже -20 ºС использовать моторные масла предписанного по SAE класса 5W‑30 или 0W‑30. Пользуйтесь только всесезонными моторными маслами.
— Указание по охране окружающей среды: в случае эксплуатации автомобиля на топливе FAME (метилэфире жирной кислоты) (биодизельном топливе) соблюдайте специальные требования и национальные предписания по утилизации моторных масел. Информацию по этому вопросу Вы можете получить в любом пункте ТО «Мерседес‑Бенц».
Интервалы замены масла зависят от:
— условий эксплуатации автомобиля,
— качества залитого моторного масла,
— вида топлива, например топлива FAME (метилэфира жирной кислоты).
Выбирайте предписанный по SAE класс (вязкость) в соответствии с температурой наружного воздуха. Данные о предписанных по SAE классах и о диапазонах температуры наружного воздуха Вы найдете в листе сортов масла №224.2 в «Предписаниях «Мерседес-Бенц» по эксплуатационным материалам».
Максимальный интервал замены масла достигается только при использовании моторных масел, отвечающих высшему стандарту качества согласно листу №228.51 «Предписаний «Мерседес-Бенц» по эксплуатационным материалам». В бортовом компьютере автоматически индицируется срок очередной замены масла.
Заливка или доливка моторного масла
Примечание:
Превышение максимального уровня масла грозит повреждением катализатора и двигателя. Откачайте излишнее моторное масло.
«Мерседес-Бенц» рекомендует доливать моторные масла того же качества и предписанного по SAE класса, которые были использованы при последней замене масла.
Проверьте уровень масла в бортовом компьютере перед доливкой моторного масла.
Смешиваемость моторных масел
Вследствие смешивания сортов масла преимущества высококачественных моторных масел уменьшаются.
Моторные масла различаются по:
— марке моторного масла,
— степени качества (номер листа),
— предписанному по SAE классу (вязкости).
Если в исключительном случае Вы не располагаете залитым в двигатель моторным маслом, долейте другой сорт допущенного «Мерседес-Бенц» моторного масла.
Установка качества масла
Примечание:
Если на дисплее бортового компьютера появляется символ
, соблюдайте при доливке указанного объема масла следующие требования:
— При заливке или доливке моторного масла более низкого качества установите более низкое качество (номер листа) в бортовом компьютере.
— При заливке или доливке моторного масла более высокого качества не устанавливайте лучшее качество (номер листа) в бортовом компьютере.
Установите номер листа (степень качества) моторного масла на дисплее бортового компьютера.
Трансмиссионные масла
Общие указания

Охлаждающая жидкость
Внимание:
— Контакт антифриза с горячими деталями в моторном отсеке может привести к воспламенению. Существует опасность пожара и травмирования! Перед доливкой антифриза дайте двигателю охладиться. Следите за тем, чтобы антифриз не проливался рядом с наливной горловиной.
— Перед запуском двигателя тщательно очищайте загрязненные антифризом детали.
На заводе автомобиль заправляется охлаждающей жидкостью, обеспечивающей защиту от замерзания и коррозии двигателя, а также другие важные защитные функции.
Охлаждающая жидкость представляет собой смесь воды и антифриза с антикоррозионными присадками.
Антифриз с антикоррозионными присадками в охлаждающей жидкости обеспечивает:
— теплопроводность,
— защиту от коррозии,
— защиту от кавитации (защиту от сквозной коррозии),
— защиту от замерзания,
— повышение точки кипения.
Оставляйте охлаждающую жидкость в системе охлаждения двигателя круглогодично— также и в странах с высокой температурой наружного воздуха.
Раз в полгода проверяйте концентрацию антифриза с антикоррозионными присадками в охлаждающей жидкости.
Пользуйтесь при этом только допущенными антифризами с антикоррозионными присадками согласно листу № 325.5. Это позволит Вам избежать повреждений системы охлаждения двигателя.
При замене охлаждающей жидкости следите за тем, чтобы охлаждающая жидкость содержала 50 объемн.% антифриза с антикоррозионными присадками. Это соответствует защите от замерзания до -37 ºС.
Не превышайте долю 55 объемн.% (защита от замерзания примерно до -45 ºС. В противном случае могут ухудшиться теплоотвод и защита от замерзания.
В случае утечки доливайте не только воду, но и в требуемой пропорции допущенный антифриз с антикоррозионными присадками.
Вода в охлаждающей жидкости должна удовлетворять определенным требованиям, которым часто отвечает питьевая вода. Если качество воды не соответствует определенным требованиям, то воду необходимо подготовить.
Смешайте воду и антифриз с антикоррозионными присадками вне контура охлаждающей жидкости. Только после этого влейте смесь в расширительный бачок охлаждающей жидкости.
Избегайте смешивания различных антифризов с антикоррозионными присадками.
Учитывайте «Предписания «Мерседес-Бенц» по эксплуатационным материалам» согласно листу №310.1.

Примечание:
Высокое серосодержание топлива ускоряет процесс старения моторного масла, а также может повредить двигатель и систему выпуска ОГ.
В автомобилях без системы нейтрализации ОГ BlueTec® серосодержание топлива установлено в соответствии с типичными показателями в стране эксплуатации автомобиля. Если Вы заправляете дизельное топливо с другим серосодержанием, установите новое значение серосодержания на бортовом компьютере. Если Вам неизвестно серосодержание используемого дизельного топлива, то установите в бортовом компьютере наиболее высокое значение серосодержания.
Информацию об актуальном специфичном для определенной страны серосодержании топлива Вы можете получить в любом пункте ТО «Мерседес-Бенц» или в «Предписаниях «Мерседес-Бенц» по эксплуатационным материалам» согласно листу № 136.1 или 136.2.
В некоторых странах предлагаются сорта дизельного топлива с различным серосодержанием. Дизельное топливо с низким серосодержанием в некоторых странах предлагается под названием «Евродизель».
Дизельное топливо при низкой температуре
Внимание:
При нагревании элементов системы питания, например при помощи пистолета горячего воздуха или открытого огня, возможно повреждение этих элементов. Это может привести к выходу на поверхность топлива и его воспламенению. В зависимости от вида повреждения выход топлива может произойти только при работающем двигателе. Существует опасность пожара и взрыва! Никогда не нагревайте элементы системы питания. Для устранения неисправности обратитесь в специализированную мастерскую с квалифицированным персоналом.
При низкой температуре наружного воздуха текучесть дизельного топлива может быть недостаточной вследствие кристаллизации парафина.
Поэтому в зимний период во избежание перебоев в работе двигателя предлагаются сорта дизельного топлива с улучшенной текучестью.
В Федеративной Республике Германия и других среднеевропейских странах зимнее дизельное топливо обеспечивает надежную эксплуатацию примерно до -22 ºС. При обычной в этом регионе температуре наружного воздуха текучесть дизельного топлива для бесперебойной эксплуатации в большинстве случаев вполне достаточна.
Автомобиль может быть оснащен устройством предварительного подогрева топлива. Устройство предварительного подогрева топлива подогревает топливо, таким образом улучшая его текучесть.
Присадки к топливу
Примечание:
Не используйте присадок к топливу. Присадки к топливу могут привести к нарушениям функций и повреждениям двигателя. Не примешивайте к дизельному топливу бензина, керосина или средств для улучшения текучести. Такие средства для улучшения текучести ухудшают смазочные свойства дизельного топлива. Это может привести к повреждениям, например, в системе впрыскивания.
Виды биодизельного топлива согласно стандарту DIN EN 14214
UCOME (Used Cooking Oil Methyl Ester)
Запрещается эксплуатировать автомобиль на биодизельном топливе, допущенном к применению согласно стандарту EN14214, произведенном из использованного пищевого растительного масла / пищевого жира = UCOME (Used Cooking Oil Methyl Ester).
Топливо FAME (метилэфир жирной кислоты) (Fatty Acid Methyl Ester)
Эксплуатация на топливе FAME (метилэфир жирной кислоты) допускается только для автомобилей BlueTec® с двигателем OM471 (код M0W). В этих автомобилях двигатель должен быть дополнительно оснащен фильтром предварительной очистки топлива (код M8Y). Информацию на эту тему Вам предоставит любая специализированная мастерская с квалифицированным персоналом.
Обязательно учитывайте указания по технике безопасности, касающиеся эксплуатационных материалов.
При эксплуатации автомобиля используйте чистое топливо FАME (метилэфир жирной кислоты) согласно стандарту DIN EN 14214. Также допускается эксплуатация автомобиля на смеси обычного дизельного топлива согласно европейскому стандарту EN 590 с топливом FAME (метилэфиром жирной кислоты).
Соблюдайте требования, касающиеся эксплуатации на топливе FAME (метилэфире жирной кислоты), согласно листу номер135 «Предписаний «Мерседес-Бенц» по эксплуатационным материалам».
При движении на топливе FAME расход топлива немного возрастает.
При использовании топлива FAME соблюдайте следующие указания:
— Интервалы замены масла, а также топливных и масляных фильтров значительно сокращаются.
— При каждой замене масла производите замену топливного или масляного фильтра. Проводите замену масла, масляных и топливных фильтров в указанных интервалах, не позднее чем каждые шесть месяцев:
• Замена топливного фильтра каждые 30000 км.
• Замена масла и масляного фильтра каждые 60000 км
— Используйте только топливо FAME, отвечающее стандарту DIN EN 14214. Присадки к топливу или топливо, не отвечающее стандарту DIN EN 14214, могут привести к нарушениям работы или к повреждению двигателя.
— Топливо FAME разъедает лакированные поверхности. Поэтому не допускайте воздействия топлива FAME на лакокрасочное покрытие. Немедленно смывайте топливо FAME водой.
— При длительной стоянке топливо FAME может привести к залипанию конструкционных элементов системы питания. Поэтому перед длительным простоем двигателя израсходуйте весь запас топлива FAME. Заполните топливный бак обычным дизельным топливом и дайте двигателю поработать, прежде чем выключить его.
— Топливо FAME подвергается естественному процессу старения. «Мерседес-Бенц» рекомендует не заправлять автомобили с длительными периодами простоя, например пожарные автомобили, топливом FAME.
Низкая температура наружного воздуха
При температуре наружного воздуха ниже 5 ºС «Мерседес-Бенц» рекомендует не использовать топливо FAME (метилэфир жирной кислоты), а использовать обычное дизельное топливо.
В зависимости от сырья и процесса производства топлива FAME (метилэфира жирной кислоты) интервал замены топливного фильтра может значительно сократиться. Помимо этого, также ухудшается способность холодного двигателя к пуску.
Альтернативные виды дизельного топлива согласно стандарту DIN EN 15940

Информация о ресивере для сжатого воздуха
Для первичных покупателей, потребителей и пользователей:
Сопроводительная документация в соответствии с директивой 2009/105/EG Европейского парламента и Совета ЕС и техническим стандартом EN 286-2.
Ресивер…:
1) Предназначен исключительно для использования в тормозных системах с пневматическим приводом и вспомогательных устройствах автомобилей, а также их прицепов и только для приема сжатого воздуха.
2) Для идентификации маркирован заводским номером и наименованием изготовителя ресивера, а также основными эксплуатационными параметрами и знаком ЕС, см. заводскую табличку или обозначения непосредственно на корпусе ресивера.
3) Изготовлен согласно «Сертификату соответствия» в соответствии со статьей 12 директивы ЕС 2009/105/EG.
4) Крепится на автомобиле крепежными лентами (хомутами).
Конструкция контактных поверхностей алюминиевых ресиверов должна исключать появление коррозии и механических повреждений. Стяжные ремни следует закрепить так, чтобы они не соприкасались с соединительными швами оснований, а ресивер не подвергался напряжениям, снижающим эксплуатационную надежность.
Покрытия алюминиевых ресиверов не должны содержать свинца, а лаки должны наноситься только с соответствующей грунтовкой. Стальные резьбовые соединения алюминиевых ресиверов должны иметь антикоррозионное покрытие:
— Обрабатывайте алюминиевые ресиверы только чистящими средствами, не содержащими щелочей.
— Производите внутренний визуальный контроль через резьбовые отверстия.
— Во избежание скопления конденсата регулярно сливайте его (кольцо на спускном вентиле расположено в самой нижней точке ресивера).
5) Не требует техобслуживания при соблюдении пункта «4)».
6) Не допускается проведение на находящихся под давлением стенках ресивера (оболочке, днищах, резьбовых кольцах) сварочных работ, термической обработки или прочих работ, способных повлиять на безопасность.
7) Кратковременные пики давления в ресивере не должны более чем на 10 % превышать максимально допустимое избыточное рабочее давление Ps.

There’re some MERCEDES Benz Actros Truck Service Manuals, Parts Catalog PDF above the page.
The first MERCEDES ACTROS was released in 1996. A few years before the debut of the advanced family, the German trucks manufacturer was thinking about updating the line of
heavy vehicles.
The SK series is outdated in many ways. The indestructible truck began to lose in demand, and the manufacturer needed something fundamentally new. As a result, the
Mercedes Actros family appeared.
The developers went a revolutionary way. From a simple predecessor in the design, there was practically nothing left. The model has noticeably changed, and a lot of electronics have appeared
inside. This had a positive effect on the quality of work and the level of comfort, but reliability decreased slightly.
The car received the standard appearance and design for heavy truck models — a large rectangular cabin and a robust chassis. Mercedes did not forget about the corporate identity.
The front part of the truck cabin was decorated with a powerful radiator grill, characteristic of the brand’s products, and a large company icon.

1General
The increase in electronic systems in the new Actros means that more and more signals now have to be made available across all the systems. This primarily has an impact on the networking, which has also gained in complexity. Alongside the familiar CAN and ASIC data bus systems the LIN data bus is now increasingly being used. The new Actros alone has 11 LIN data buses, which connect the various control units, switches or other electronic components to each other. The number of CAN data buses by contrast has only risen slightly.
2CAN data bus system
The CAN data bus system enables information to be exchanged quickly and reliably between control units over only a few lines. The information is sent or received successively (serial). The exchange is bidirectional, i.e. each control unit operates as both a transmitter and a receiver.
2.1 Transfer rates
In the new Actros up to 13 different CAN data buses are used. The majority of these CAN data buses have a transfer rate of >250 kBaud and this classes them as high>speed CAN data buses. The reasons for the increase in high>speed CAN data buses are:
•Increase in data rate (number of messages that are sent)
•Almost identical manufacturing costs as for low>speed CAN data buses
•Greater use of LIN data bus in non>critical safety areas
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
•Shortening of flash or parameterization times, in particular through increase in transfer rate for diagnostic CAN (CAN 10)
The following CAN data buses have a transfer rate of 500 kBaud:
•Exterior CAN (CAN 1)
•Interior CAN (CAN 2)
•Frame CAN (CAN 3)
•Climate control CAN (CAN 5)
•Front axle brake CAN (CAN 6a)
•Rear axle brake CAN (CAN 6b)
•Redundancy brake CAN (CAN 6c)
•Brake CAN ESP“ (CAN 6d)
•Diagnostic CAN (CAN 10)
•Radar CAN (CAN 12)

Functions
The transfer rate of the drive train CAN (CAN 4) was increased to 667 kBaud, because the high number of messages had significantly increased the bus operating rate. If the data rate was not increased, then there is the risk that some messages with low priority could no longer be sent due to the bus operating rate.
To ensure that freight forwarders, for example for fleet management, can continue to call up specific information on vehicle location, current speed, etc. the transfer rate of the telematics CAN (CAN 9) has been retained at 250 kBaud.
The transfer rates have also been retained on the trailer CAN (PSM) (CAN 7), the body manufacturer CAN (PSM) (CAN and the trailer CAN (EBS) (CAN 11). They are 125 kBaud, whereby they are still classified as low>speed CAN data buses.
The transfer rate for the NOx>CAN (CAN 13) has not been changed either and is > as before > 250 kBaud.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
2.3CAN neutral points and bus terminating resistors
Because of the high transfer rates on high>speed CAN data buses, there may be some reflections in the lines. Bus termination resistors are used to avoid reflections that would lead to the falsification of actual information. The characteristic impedance of the electrical line is important for the bus termination resistor. The total bus terminating resistor on a high>speed CAN data bus is 60 ].
In the neutral points for the cab instrument panel CAN bus (Z1) and frame CAN bus (Z3) the bus terminating resistors are integrated into the neutral points. The drive CAN bus neutral point (Z4) only includes those ferrite elements that are also installed in the neutral points for interference suppression of
high>frequency interference pulses.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
3LIN data bus
The LIN data bus is an inexpensive serial subbus, which replaces the CAN data bus in the area of uncritical data transfer. The voltage supply for the LIN data bus is 12 V. This is realized internally in the control units through voltage dividers. Signals are transmitted through a single>wire line. The max. data rate is 20 kBaud. Communication refers to ID>based communication. All subscribers connected to the LIN data bus receive the message, but only one subscriber responds to it.
A LIN data bus subscriber never sends information by itself, as is the case, for example with a CAN data bus subscriber. Subscribers of the LIN data bus only ever respond to a query.
2.2Gateways
To compensate for the different transfer speeds, some control units also act as a gateway:
•The central gateway control unit (CGW) (A2) routes the respective messages from the exterior, interior, frame, telematics and diagnostic CAN (CAN 1, 2, 3, 9 and 10).
•The modular switch panel (MSF) control unit (A43) acts as a gateway between the interior CAN (CAN 2), the ASIC data bus (ASIC) and the three LIN data buses to the button groups on the multifunction steering wheel, the left multifunction control lever and the level control operating unit.
•The Electronic Brake Control (EBS) control unit (A10b) or (A10c), depending on the version, sends the messages from the frame CAN (CAN 3) to the front axle brake CAN (CAN 6a), the rear axle brake CAN (CAN 6b), the brake CAN ESP“ (CAN 6d) as well as, where applicable, the trailer CAN (EBS) (CAN 11) and vice versa.
•The drive control (CPC) control unit (A3) acts as an interface between the frame CAN (CAN 3) and the drive train CAN
(CAN 4).
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
The bus terminator on the exterior CAN (CAN 1) is realized by using bus terminating resistors within the central gateway control unit (CGW) (A2) and the Electronic Air>Processing Unit (EAPU) control unit (A18). Located in both control units is a 120 ] resistor each. The parallel connection then yields a total bus terminating resistance of 60 ].
In the diagnostic CAN (CAN 10) the bus terminator is realized by a 60 ] resistor in the central gateway control unit (CGW) (A2).

4ASIC data bus system
The previously familiar ASIC data bus system is also used in the new Actros.
The ASIC data bus (ASIC) belongs to the so>called subbuses. In contrast to conventional switches which switch via their own contacts and are connected to their components via separate electrical lines (e.g. motors, solenoid valves, switch inputs, lighting devices), the ASIC data bus performs these tasks.
The electronics installed in the ASIC signal switches notifies the modular switch panel (MSF) control unit (A43) the following via the ASIC data bus (ASIC):
fswitch position (open, closed, operated, not operated)
fFunctionality (normally closed contact, normally open contact, changeover contact)
fSystem affiliation (e.g. headlamp cleaning system button,
power take>off 1 button, etc.)
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
5Virtual control units
Each ASIC signal switch is connected over three contacts (pins) to the ASIC data bus (ASIC), and it is evaluated by the modular switch panel (MSF) control unit (A43). It is thus possible to install each ASIC signal switch at any arbitrary point on the individual switch modules.
For currents up to a maximum of 20 A there continues to be load switches which as before switch via their own contacts and are connected to their components through electrical lines.
These load switches are only connected to the switch panel via the ASIC contacts for separate background lighting.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
6Safety strategy
Virtual control units are not equipped with their own housing. They are integrated into the hardware and software of other control units. In Star Diagnosis and the instrument cluster control unit (ICUC) (A1) they appear as independent control units. Among the virtual control units are the central data memory (CDS) (A2 a1), the communications interface (COM) control unit (A2 a2) and the maintenance system (MS) control unit (A2 a3), which are all integrated into the central gateway control unit (CGW) (A2).
With the aid of the central data memory (CDS) (A2 a1) the parameters for the electronic control units can be reset to manufacturer default settings.
Several control units have a redundant connection over LIN or CAN data buses. The redundant connection serves as an emergency communication, if the actual CAN connection malfunctions. The use of redundant LIN or CAN data buses is dependent on the safety relevance of each system.
The service brake system, for example has a redundant CAN data bus connection between the axle modulators.
LIN data buses serve as redundancies between the sensor and actuator module, cab (SCA) control unit (A7) and the sensor and actuator module, chassis (SCH) control unit (A8) as well as between the instrument cluster control unit (ICUC) (A1) and the Electronic Air>Processing Unit (EAPU) control unit (A18).

Functions
General information
The recording of data function enables the maintenance system (WS) to receive two different types of input factors for calculating the load>specific maintenance intervals:
fBasic data, which are determined unchangeable at first in the form of a parameterization and
fmeasured values, which are sensed continuously.
Thus, two functions are differentiated:
fAcquiring the basic data
fAcquiring the measured values
Acquiring the basic data
The maintenance system (WS) requires certain basic data (parameters), which:
fare a prerequisite for the general function and
fwhich are used to adapt the maintenance system (WS) to the vehicle and the operating fluids.
The basic data are acquired in the form of the following parameterizations:
fBasic parameterization
fVehicle>specific parameterization
fSubsequent parameterization
fParameterization of operating fluids
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Subsequent parameterization
Subsequent parameterization:
fmakes it possible to change parameters, which are connected to constructional vehicle changes for instance or special customer’s requests, such as the «time>based servicing scheme grid» parameter and
fmay only be carried out in workshops authorized by Mercedes>Benz.
i Querying and operation are conducted using the left multifunction steering wheel button group (S110) and right multifunction steering wheel button group (S111) or using Star Diagnosis through the diagnostic socket (X100.16).

their cut>in or cutout and
fis carried out in the Mercedes>Benz production plant.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Parameterization of operating fluids
Parameterization of operating fluids:
fmakes it possible to change parameters with regard to the properties of fuels and lubricants, which can change during the operation of the vehicle, such as engine oil quality, engine oil viscosity, transmission oil quality, or sulfur content of the fuel and
fmay also be carried out by other workshops.
i The parameters can be checked and changed if necessary through the «Fuels and Lubricants» submenu in the «Adjustments» menu of the menu system. Querying and operation are conducted using the left multifunction steering wheel button group (S110) and right multifunction steering wheel button group (S111) or using Star Diagnosis through the

Forecast calculation, function |
2.8.11 |
MODEL 963
General information
A forecast is used to schedule the vehicle’s visit to the workshop beforehand.
The maintenance system (WS) calculates the individual forecast data for each maintenance item during each calculation cycle:
fRemaining total time
fRemaining driving distance
fMaintenance date
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Forecasting start
As long as the life cycle consumption is still below the forecasting start, no forecast data are calculated. There is not yet a sufficient amount of information below the forecasting start to be able to calculate reliable forecast data.
After each reset the forecast data are marked «not predictable» by the base parameterization. After exceeding the forecasting start, the predictions are calculated based on the current life cycle consumption values.
The forecasting start for accumulated, directly measured maintenance items and for time>based servicing schemes lies at 50 h operating time.
Forecasting
The forecast data are calculated individually for each maintenance item. As a result, the service dates of the individual maintenance items do not have a fixed time interval between one
another.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Time>based servicing
The life cycle consumption increases irrespective of the load of the maintenance item in proportion to the elapsed time.
The service date depends exclusively on the calculated remaining total time. The remaining total time is calculated beginning with the start of the total time calculation.
The prognosis calculation is based on the following input parameters:
fTotal time
fOperating time
fDistance
fLife cycle consumption
The service date of the time>based servicing scheme is exclusively specified via the parameterizable time maintenance grid. The forecast data are issued on the multifunction display (A1 p1) in
the instrument cluster (ICUC) (A1).
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Thus, the workshop equipment is optimally utilized.
The forecast data for the remaining total time and the remaining driving distance apply exactly to each service date of a maintenance item and represent the remainder values until the due date.
The individual service date for each maintenance item is the point in time at which the next maintenance is due.
i This applies provided the workshop equipment is used with a constant load.
If maintenance items are close to each other, then a decision should be reached in consultation with the customer as to whether they can be conducted together during a maintenance visit to the workshop.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
After confirmation of a conducted time>based servicing scheme, the new service date is displayed in the multifunction display (A1 p1).
The remaining distance is shown after 50 operating hours for the first time in the multifunction display (A1 p1).

General information
The life cycle consumption calculation provides information on the degree to which the workshop equipment is worn out, and which one should be replaced or repaired during maintenance.
The life cycle consumption calculation determines 4 life cycle consumption values, which are calculated anew during each calculation cycle:
fLife cycle consumption based on vehicle load, based on calculation method for:
>directly measured maintenance items and
>accumulating maintenance items.
fLife cycle consumption based on the drive time limit,
fLife cycle consumption based on the travel distance limitation,
fLife cycle consumption based on operating time,
The workshop equipment is worn out if a life cycle consumption of 100% is reached.
An exception is the time>based servicing scheme, which has fixed maintenance intervals that are independent from loads and driving distance.
The life cycle consumption is the basis for forecasting.
i Very precise, earlier prognoses are possible in the event of regular operations in regard to loads and driving distance over a long period of time. If operations vary greatly, the prognosis variation is higher. The forecasts become increasingly more accurate as total vehicle operating time increases.
Once the four life cycle consumption values have been evaluated, the maintenance system (WS) provides the highest value as a forecasting life cycle parameter.

1General
With transmission automation there a convenience shifting system available over which gear selection as well as declutching and engaging of the clutch take place automatically. It contains a fully automated manual transmission, based on a constant>mesh transmission, with automated clutch operating system. The clutch operation takes place over a pneumatically actuated centrally located clutch operator.
Synchronization does not take place via a blocking synchronization as on a synchromesh transmission but is realized instead by braking or accelerating the countershaft in a controlled manner. As a result can be widened for the same dimensions of the transmission gears and thus higher torques and outputs transmitted. Passive safety is also increased due to reducing the
burden for the driver.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Optimum gear selection supports an economic and fuel>saving driving style. All the shift operations take place in the optimum rpm range, minimizing wear on the transmission and engine.
Faults during shifting are ruled out and it is no longer possible to over rev the engine. After switching on the ignition the automatic mode of transmission automation is always activated irrespective of which mode was last selected (manual or automatic). The option of activating a manual or automatic shift mode with the transmission mode button (M/A) (S23 s3) on the RH multifunction control lever (S23) has been retained. 12 forwards gears, 4 reverse gears and neutral can be engaged.

6Transmission cooling (for code N6Z)
A thermostatically regulated transmission cooling with the following components is used as special equipment:
fTransmission cooler with a transmission cooling fan (M19) (located in the direction of travel on the right, next to the cooling module)
fTransmission oil lines
fThermostat element with spring from the shape memory alloy (FGL)
For transmission oil temperatures above 80∞C the spring force of the spring closes the cooler protection valve (bypass). The transmission oil flows through the transmission cooler and is cooled by the airstream.
If the transmission oil temperature increases further, the transmission cooling fan (M19) located on the transmission cooler is switched on from 90∞C over the SCA (SCA) control unit (A7).
For transmission oil temperatures below 80∞C the spring opens the cooler protection valve. The transmission oil flows uncooled over the bypass back into the transmission.
i In the case of an excessively high transmission oil pressure the cooler and the transmission protection valve open and allow the oil to flow uncooled over a bypass back into the transmission.

Functions
Operation of the driving functions
The driving functions assist the driver in daily driving to drive with a more fuel economy. They increase the ride comfort and support him in difficult situations.
Selectable driving functions are:
fEcoRoll mode, in certain driving situations for supporting a fuel>saving driving style through automatic shifting into the transmission neutral position «N» when the accelerator is not actuated
fRocking mode, for rocking the vehicle out of an off>road recess
fCrawl mode, for automatic starting moving when releasing the service brake and continued crawling without actuating
the accelerator pedal.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Function sequence
If the pre>conditions are fulfilled then the drive control (CPC) control unit (A3) requests the neutral position from the transmission (TCM) control unit (A5) via the drive train CAN (CAN 4). The transmission (TCM) control unit (A5) actuates the transmission positioner (Y900) to open the clutch. After successful opening of the clutch, read in over the clutch position sensor (B503), the transmission positioner (Y900) is actuated to engage neutral. After ending the switching the transmission (TCM) control unit (A5) transmits the engaged neutral to the drive control (CPC) control unit (A3) via the drive train CAN (CAN 4).
i Based on the reduced engine speed a somewhat lower steering assist can occur and therefore greater steering forces in certain driving situations, for example on slightly curved downslopes. The operation or road safety is not endangered by this.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Function sequence
The crawl function consists of 2 parts:
fIn gears 1 to 6, R1 and R2, self>actuated starting crawling by releasing the service brake (only for an active crawl function)
fIn gears 1 to 6, R1 and R2 further crawling (=freewheeling)
for a non>actuated accelerator pedal
The driving off dosing occurs for first driving off over the accelerator pedal. The system is taught in in the process to the torque prescribed by the driver. After the first «real» driving determination of the crawling torque depends on the determined vehicle mass and incline in the driving lane.
i If driving with a trailer is recognized over the trailer recognition the mass and incline dependent crawling torque is reset in the drive control (CPC) control unit (A3) and teaching in
occurs again during first driving off.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
EcoRoll mode
Preconditions
fEcoRoll function activated
fGround speed was > 35 km/h and is > 25 km/h (hysteresis)
fAccelerator not operated
fService brake or permanent brake not actuated
fDriver assistance systems not in control mode
fBrake assistant systems not in control mode
fPower take>off switched off
fVariable speed limiter maximum speed not exceeded
fCC speed tolerance not exceeded
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Crawl mode
The crawl function is always switched on after an engine start and is activated after first moving off.
The crawl function is deactivated under the following conditions:
fThe crawl function is switched off over the IC (ICUC) control unit (A1)
fThe transmission in neutral for longer than 2 s
fThe parking brake is tightened
fThe rocking mode is activated
fDriver assistance systems switch into control mode
fIdle speed > 700 rpm
fThreat of clutch overloading
fAn excessively high air drag and rolling resistance
fAn excessively high tire grip
i The crawl function is similar in its behavior to an automatic torque converter. Since the function is realized over the clutch the function is not wear>free and the vehicle in the slip range of the
clutch is not capable of permanently crawling.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Rocking mode Function sequence
Rocking mode is activated over the rocking mode button (S938). If rocking mode has been activated the transmission control changes from automatic into manual mode.
Accelerator pedal requests are implemented more directly and the clutch is opened more rapidly for a non>actuated accelerator pedal. The clutch is closed quickly again as soon as the accelerator pedal is actuated again. Through repeated actuation and release of the accelerator pedal can put the vehicle into a rocking mode condition and in this way can rock the vehicle free out if a hollow.

Functions
Back>up mode
Back>up mode represents a last emergency function for engaging gears for a vehicle standstill. The operating commands for navigation are entered in the menu tree multifunction display (A1 p1) in the IC (ICUC) control unit (A1) over the LH multifunction steering wheel button group (S110) and the RH multifunction steering wheel button group (S111).
The modular switch panel (MSF) control unit (A43) reads in the switching commands from the LH multifunction steering wheel button group (S110) and the RH multifunction steering wheel button group (S111), evaluates them and transmits appropriate CAN messages via the interior CAN (CAN 2), the central gateway (CGW) control unit (A2) and the frame CAN (CAN 3) to the drive control (CPC) control unit (A3).
The drive control (CPC) control unit (A3) evaluates the switching request from the driver, determines the targeted gear to be switched and, for release, transmits appropriate CAN messages via the drive train CAN (CAN 4) to the transmission (TCM) control unit (A5).
The following switching positions can be selected in back>up mode:
fR (for reverse gear)
fN (for neutral)
fD1 (for 2nd gear)
fD2 (for 6th gear)
fTowing (for the towing mode)
The actuation of the clutch is controlled automatically as long as no malfunction is present. A malfunction would result in automatic clutch operation being disabled.
i If gear selection was not enabled, a shift to «neutral» is always enabled.

Displaying shift status
The drive control (CPC) control unit (A3) transmits the information for indication of the switching condition to the IC (ICUC) control unit (A1) via the frame CAN (CAN 3).
To do this the transmission (TCM) control unit (A5) permanently transmits the CAN messages with information about the condition of the transmission (for example the engaged gear, the possible gear) to the drive control (CPC) control unit (A3) via the drive train CAN (CAN 4). Before execution of the shift operation the drive control (CPC) control unit (A3) transmits the targeted gear request (determined from the automatic gear selection or the gear selected by the driver) to the transmission (TCM) control unit (A5). The transmission (TCM) control unit (A5) transmits the confirmed targeted gear and the engaged current gear to the drive control
(CPC) control unit (A3) .
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Emit warning tones acoustically
The transmission (TCM) control unit (A5) transmits CAN messages with information concerning the condition of the transmission (for example on the switched gear, the possible gear, temperature of the transmission oil) to the drive control (CPC) control unit (A3) via the drive train CAN (CAN 4).
The IC (ICUC) control unit (A1) receives the CAN messages and generates the following displays in the multifunction display (A1 p1):
fdisplay of the direction of travel and / or the engaged gear
fdisplay of the gearshift recommendation or to engaged gear
fdisplay of the transmission mode
The previous display is retained during the shift operation. The current display only takes place when the shift operation is concluded.
i During the teach>in process appropriate CAN messages are transmitted with information for display of the active teach>in process. Also in back>up mode all CAN messages are transmitted, as in normal mode, via the drive control (CPC) control unit (A3) and the frame CAN (CAN 3) to the IC (ICUC) control unit (A1).
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
The drive control (CPC) control unit (A3) decides over a warning emission to the driver. If a warning emission is necessary, the drive control (CPC) control unit (A3) transmits an appropriate CAN message with the information for output of warning tones to the IC (ICUC) control unit (A1) via the frame CAN (CAN 3).
The IC (ICUC) control unit (A1) receives the CAN messages from the drive control (CPC) control unit (A3) and generates acoustic messages whose output takes place over the center speaker (B50).

General information
One can select between a manual transmission mode (manual operation) or an automatic transmission mode (automatic operation). In automatic operation there is a standard switching program (A) and either the shift program (A power) or the shift program
(A economy) available depending on the vehicle and transmission design.
Automatic transmission mode
The transmission automation is fitted with a standard shift program:
fA, with kickdown, accelerator pedal curve standard, CC standard, maximum speed of 89.8 km/h, function EcoRoll which can be switched off
The driving specific shift programs have the following significant properties:
fA power, switchings take place at an about 100 rpm higher rotational speed in comparison with a standard shift program and dynamic clutch matching for driving off
fA economy, no kickdown possible, EcoRoll cannot be switched off, maximum speed of 85 km/h, accelerator pedal curve and max. engine torque lowered, CC Softcruise
i Selection of the automatic transmission mode takes place over the transmission mode button (M/A) (S23 s3) on the RH multifunction control lever (S23).
Manual transmission mode
In manual transmission mode the shift operations are initiated by the driver over it. This means that the driver determines the shift point and the switching direction. The kickdown function is not available.

Functions
1General
The transmission control (TCM) control unit (A5) is, as the interface to the transmission, the central control electronics for shift operation of a gear and actuation of the clutch.
It controls the entire shift operation and in the process performs the following tasks:
fSwitching the switching groups of the transmission
fMeasuring and evaluating the shift status and operating condition of the transmission
fMeasuring and evaluating the shift status and operating condition of the clutch
fRegulation and positioning of the clutch
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
3Shifting the transmission
Actuation of the components cylinder valve gear extend solenoid (Y900 y8), gear cylinder retract solenoid valve (Y900 y9), splitter group extend solenoid valve (Y900 y6), splitter group retract solenoid valve (Y900 y7), range group retract solenoid valve (Y900 y12), range group extend solenoid valve (Y900 y13), gate cylinder extend solenoid valve (Y900 y10), gate cylinder retract solenoid valve (Y900 y11) takes place over electrical shift signals from the transmission control (TCM) control unit (A5).
The sequence of actuation is carried out as per a specified sequence corresponding to the gear to be shifted. The solenoid valves control the admission and release of air into/out of the working spaces of the associated gate shift cylinder (1), range group shift cylinder (2), gear cylinder (3) and splitter group shift cylinder (4). In the process their piston rods assume a defined position and operate the associated shift mechanism for shifting
the splitter, range group, gear and gate.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
3.3Shifting the splitter group
The splitter group is switched through actuation of the splitter group extend solenoid valve (Y900 y6) or splitter group retract solenoid valve (Y900 y7).
3.4Shifting the gate
The gate is switched through actuation of the gate cylinder retract solenoid valve (Y900 y11).
i There is a spring in the shift mechanism to reset the transmission shift rod. This ensures that there is the necessary return force present for a non> actuated gate cylinder retract solenoid valve (Y900 y11). The return force of the spring is also supported as required through actuation of the gate cylinder extended solenoid valve (Y900 y10).
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
2CAN communication
The transmission control (TCM) control unit (A5) which is located above the overall network is in constant data exchange with other control units which provide switching relevant data.
It is in direct connection with the drive control (CPC) control unit (A3) and the engine management (MCM) control unit (A4) via the drive train CAN (CAN 4). Also requests from the transmission control (TCM) control unit (A5) to other control units (e.g. rotational speed requests to the engine) are transmitted via the drive train CAN (CAN 4).
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
3.1Controlling the clutch
Actuation of the components clutch slow close solenoid valve (Y900 y1), clutch slow open solenoid valve (Y900 y2), clutch rapid close solenoid valve (Y900 y3), clutch rapid open solenoid valve (Y900 y4) occurs over electrical shift signals from the transmission control (TCM) control unit (A5).
The solenoid valves control the aeration and ventilation of the pneumatic central clutch release bearing (7). The pneumatic central clutch release bearing (7) opens or closes the clutch or regulates the clutch at a particular position.
3.2Switch the range group
Condition: the neutral position of gear cylinder (3) was detected. The range group is switched through actuation of the range group retract solenoid valve (Y900 y12) or the range group extend solenoid valve (Y900 y13).
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
3.5Switch the gear
The gears are switched through actuation of the gate cylinder extend solenoid valve (Y900 y8) or the gate cylinder retract solenoid valve (Y900 y9). The shift operation starts from the neutral position.
i The rotational speed of the countershaft must be aligned with the rotational speed of the main shaft before switching the gear. This occurs for upshifting through actuation of the countershaft brake solenoid valve (Y900 y5) as well as for downshifting through raising the engine speed for a closed clutch.
3.6Shifting gears in towing mode
Towing mode is only possible in back>up mode and if the electrical and pneumatic components are functioning correctly. Towing mode comprises automatic shifting of the high>speed range
group and of the neutral position.

There are fault codes with detailed interpretation, description of the parameters of the self-diagnosis menu, electrical and pneumatic circuits.
The disk will be useful to those who deal primarily with the repair of the Actros.
