    FI SYSTEM DIAGNOSIS 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 222 FI SYSTEM DIAGNOSIS 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 223 FI SYSTEM DIAGNOSIS 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.

    FI SYSTEM DIAGNOSIS 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.

    FI SYSTEM DIAGNOSIS 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.
