    VL1500K5 (’05-MODEL) PRECAUTIONS IN SERVICING When handling the FI component parts or servicing the FI sys- tem, observe the following points for the safety of the system. CONNECTOR/COUPLER • When connecting a connector, be sure to push it in until a click is felt.
  • Page 21 VL1500K5 (’05-MODEL) • 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.
  • Page 22 VL1500K5 (’05-MODEL) Ignition S/W • When disconnecting and connecting the ECM couplers, make sure to turn OFF the ignition switch, or electronic parts may get damaged. • Battery connection in reverse polarity is strictly prohibited. INCORRECT Such a wrong connection will damage the components of the FI system instantly when reverse power is applied.
  • Page 23: Electrical Circuit Inspection Procedure

    VL1500K5 (’05-MODEL) 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 circuit are as follows. As the cause can exist in the connector/coupler or terminal, they need to be checked carefully.
  • Page 24 VL1500K5 (’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. • Disconnect the coupler B and measure resistance between couplers A and B.
  • Page 25 VL1500K5 (’05-MODEL) SHORT CIRCUIT CHECK (WIRE HARNESS TO GROUND) • Disconnect the negative cable from the battery. To other • Disconnect the connectors/couplers at both ends of the circuit parts to be checked. NOTE: If the circuit to be checked branches to other parts as shown, disconnect all connectors/couplers of those parts.
  • Page 26 VL1500K5 (’05-MODEL) USING THE MULTI-CIRCUIT TESTER • Use the Suzuki multi-circuit tester (09900-25008). • Use well-charged batteries in the tester. • Be sure to set the tester to the correct testing range. USING THE TESTER MULTI-CIRCUIT TESTER • Incorrectly connecting the + and - probes may cause the inside of the tester to burnout.
  • Page 27: Fi System Technical Features

    VL1500K5 (’05-MODEL) 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 the intake air pressure, engine speed and throttle opening angle, and various compensations.
  • Page 28: Injection Stop Control

    VL1500K5 (’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 OIL TEMPERATURE SENSOR When engine oil temperature is low, injection time (volume) SIGNAL is increased.
