DRIVER INFORMATION SYSTEM

CONTENTS

●To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be per-

formed by an authorized NISSAN/INFINITI dealer.

●Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air

Bag Module, see the SRS section.

●Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or

harness connectors.

When reading wiring diagrams, refer to the following:

●GI-14, «How to Read Wiring Diagrams» in GI section

●PG-2, «POWER SUPPLY ROUTING» for power distribution circuit in PG section When performing trouble diagnosis, refer to the following:

●GI-10, «HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES» in GI section

●GI-26, «How to Perform Efficient Diagnosis for an Electrical Incident» in GI section

System Description

UNIFIED METER CONTROL UNIT

●Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the unified meter control unit, which is built into the combination meter.

●Digital meter is adopted for odo/trip meter*.

*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter is erased when the battery cable is disconnected.

●Meter/gauge and odo/trip meter segments can be checked in diagnosis mode.

POWER SUPPLY AND GROUND CIRCUIT

Power is supplied at all times

●through 10 A fuse [No. 28, located in the fuse block (J/B)]

●to combination meter terminal 1.

With the ignition switch in the ON or START position, power is supplied

●through 10 A fuse [No. 11, located in the fuse block (J/B)]

●to combination meter terminal 2.

Ground is supplied

●to combination meter terminal 21

●through grounds M27 and M70.

ODO/TRIP METER, CLOCK AND AMBIENT TEMPERATURE INDICATOR

●The vehicle speed signal and the memory signals from the meter memory circuit are processed by the combination meter and the mileage is displayed.

●Ambient temperature indicator indicates signal from ambient sensor processed by the combination meter.

How to Change The Display

Depressing the odo/trip meter switch toggles the mode in the following order.

SKIA8917E

●The odo/trip meter display mode toggling and trip display resetting can be identified by the amount of time that elapses from pressing the odo/trip meter switch to releasing it.

●When resetting with trip A displayed, only trip A display is reset. (The same way for trip B.)

SPEEDOMETER

VDC/TCS/ABS control unit [with VDC] or ABS actuator and electric unit (control unit) [without VDC] provides a vehicle speed signal to the combination meter for the speedometer with CAN communication line.

COMBINATION METERS

–In a case of less then 3.5 hours after turning ignition switch off, temperature at the time of turning ignition switch off is indicated.

●In a case that temperature detected by ambient sensor is lower than indicated temperature before turning ignition switch off.

–Temperature detected by ambient sensor is indicated when turning ignition switch on.

Indication During Running

Though temperature detected by ambient sensor temporarily changed, indicating temperature continentally indicates.

●In a case that temperature detected by ambient sensor is higher than indicated temperature.

–If vehicle speed is more than 20 km/h (13 MPH), elevation of indicating temperature is limited according to the speed until temperature detected by ambient sensor is indicated.

NOTE:

Vehicle speed 20 km/h (13 MPH): 256 sec., 25 km/h (16 MPH): 238 sec., 35 km/h (22 MPH): 200 sec., 50 km/h (31 MPH): 144 sec., 65 km/h (40 MPH): 88 sec., more than 80 km/h (50 MPH): 32 sec.

–If vehicle speed is more than 20 km/h (13 MPH), and that temperature detected by ambient sensor becomes 8 ° C (46 ° F) more than indicating temperature, indicating temperature will be elevated unit the

degree becomes same as temperature detected by ambient sensor with limiting elevation of indicating temperature 1 ° C par a minute.

–If vehicle speed is less than 20 km/h (13 MPH), indicating temperature is continually kept.

● In a case that temperature detected by ambient sensor is lower than indicated temperature.

–Temperature detected by ambient sensor is indicated during running.

SYSTEM DESCRIPTION

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

CAN COMMUNICATION UNIT

Refer to LAN-16, «CAN Communication Unit» in “LAN SYSTEM”.

SELF-DIAGNOSIS FUNCTION

●Odo/trip meter segment operation can be checked in self-diagnosis mode.

●Meters/gauges can be checked in self-diagnosis mode.

OPERATION PROCEDURE

1.Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.

NOTE:

If the diagnosis function is activated with the trip meter A displayed, the mileage on the trip meter A will indicate 0.0 mile, but the actual trip mileage will be retained. (The same way for trip B.)

2.Turn ignition switch OFF.

3.While pushing the odo/trip meter switch, turn ignition switch ON again.

4.Make sure that the trip meter displays “0.0”.

5.Push the odo/trip meter switch at least 3 times. (Within 7 seconds after the ignition switch is turned ON.)

6.All the segments on the odo/trip meter illuminate, and simultaneously the low-fuel warning lamp indicator illuminates. At this time, the unified meter control unit is turned to diagnosis mode.

NOTE:

If any of the segments is not displayed, replace the combination meter.

5. CHECK LOW-FUEL WARNING LAMP ILLUMINATION

During inspection of low-fuel warning lamp, confirm illumination of low-fuel warning lamp.

6. CHECK METER CIRCUIT

Check indication of each meter/gauge in self-diagnosis mode.
