    14-18 VL800K5 (’05-MODEL) PRECAUTIONS IN SERVICING When handling the component parts or servicing the FI system, observe the following points for the safety of the system. ELECTRICAL PARTS CONNECTOR/COUPLER • When connecting a connector, be sure to push it in until a Click click is felt.

  • Page 371
    VL800K5 (’05-MODEL) 14-19 • When connecting meter probe from the terminal side of the coupler (where connection from harness side not being possi- ble), use extra care not to force and cause the male terminal to bend or the female terminal to open. Connect the probe as shown to avoid opening of female ter- minal.
  • Page 372
    14-20 VL800K5 (’05-MODEL) • When disconnecting and connecting the ECM, make sure to turn OFF the ignition switch 1, or electronic parts may get damaged. INCORRECT • Battery connection in reverse polarity is strictly prohibited. Such a wrong connection will damage the components of the FI system instantly when reverse power is applied.

  • Page 373: Electrical Circuit Inspection Procedure

    VL800K5 (’05-MODEL) 14-21 ELECTRICAL CIRCUIT INSPECTION PROCEDURE While there are various methods for electrical circuit inspection, described here is a general method to check for open and short circuit using an ohmmeter and a voltmeter. OPEN CIRCUIT CHECK Possible causes for the open circuits are as follows. As the cause can exist in the connector/coupler or terminal, they need to be checked carefully.

  • Page 374
    14-22 VL800K5 (’05-MODEL) Continuity check • Measure resistance across coupler B (between A and C in the figure). If no continuity is indicated (infinity or over limit), the circuit is open between terminals A and C. 1 ECM • Disconnect the coupler B and measure resistance between couplers A and B.
  • Page 375
    VL800K5 (’05-MODEL) 14-23 SHORT CIRCUIT CHECK (WIRE HARNESS TO GROUND) • Disconnect the negative cable from the battery. • Disconnect the connectors/couplers at both ends of the circuit to be checked. NOTE: If the circuit to be checked branches to other parts as shown, disconnect all connectors/couplers of those parts.
  • Page 376
    14-24 VL800K5 (’05-MODEL) USING THE MULTI-CIRCUIT TESTER • Use the Suzuki multi-circuit tester set (09900-25008). • Use well-charged batteries in the tester. • Be sure to set the tester to the correct testing range. USING THE TESTER • Incorrectly connecting the + and — probes may cause the inside of the tester to burnout.

  • Page 377: Fi System Technical Features

    VL800K5 (’05-MODEL) 14-25 FI SYSTEM TECHNICAL FEATURES INJECTION TIME (INJECTION VOLUME) The factors to determine the injection time include the basic fuel injection time, which is calculated on the basis of intake air pressure, engine speed and throttle opening angle, and various compensations. These compensations are determined according to the signals from various sensors that detect the engine and driving conditions.

  • Page 378: Injection Stop Control

    14-26 VL800K5 (’05-MODEL) COMPENSATION OF INJECTION TIME (VOLUME) The following different signals are output from the respective sensors for compensation of the fuel injection time (volume). SIGNAL DESCRIPTION ENGINE COOLANT TEMPERATURE SEN- When engine coolant temperature is low, injection time (vol- SOR SIGNAL ume) is increased.

This data is called “Show data when trouble”. Therefore, it is possible to know engine and driving conditions (e.g., whether the engine was warm or not, where the motorcycle was running or stopped) when a malfunction was detected by checking the show data when trouble.
