  • Page 161: Electrical Circuit Inspection Procedure

    4-6 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 162
    FI SYSTEM DIAGNOSIS 4-7 Continuity check • Measure resistance across coupler (between the figure). If no continuity is indicated (infinity or over limit), the circuit is open between terminals • Disconnect the coupler and measure resistance between couplers If no continuity is indicated, the circuit is open between cou- plers .
  • Page 163
    4-8 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.
  • Page 164: Using The Multi-Circuit Tester

    FI SYSTEM DIAGNOSIS 4-9 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 probes may cause the inside of the tester to burnout.

    4-10 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.

    FI SYSTEM DIAGNOSIS 4-29 SHOW DATA WHEN TROUBLE (DISPLAING DATA AT THE TIME OF DTC) ECM stores the engine and driving conditions (in the form of data as shown in the figure) at the moment of the detection of a malfunction in its memory. 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.

    6-2 EXHAUST SYSTEM EXHAUST SYSTEM EXHAUST CONTROL SYSTEM The exhaust control system (EXCS) consists of the exhaust control valve (EXCV), exhaust control valve actuator (EXCVA) and exhaust control valve cables (EXCV cables). EXCV is installed in the exhaust pipe. EXCVA is mounted inside of the right frame. The EXCV is operated by the EXCVA via the cables.

  • Page 300: Operation

    EXHAUST SYSTEM 6-3 OPERATION The EXCS is operated by the signal supplied from the ECM. The open/close operation of the EXCV is performed by the EXCVA which is controlled by the ECM by changing the current direction of the actuator motor. The position sensor (incorporated in the EXCVA) detects the EXCVA movement by measuring the voltage and then the ECM determines the EXCV opening angle based on the engine rpm and gear positions.

    11-2 EMISSION CONTROL INFORMATION EMISSION CONTROL SYSTEMS FUEL INJECTION SYSTEM GSX-R1000 motorcycles are equipped with a fuel injection system for emission level control. This fuel injection system is precision designed, manufactured and adjusted to comply with the applicable emission limits. With varying engine conditions, all of the fuel injection volumes are precisely controlled by the programmed injection maps in the ECM to reduce CO, NOX and HC.

  • Page 540: Crankcase Emission Control System

    EMISSION CONTROL INFORMATION 11-3 CRANKCASE EMISSION CONTROL SYSTEM The engine is equipped with a PCV system to prevent discharging crankcase emissions into the atomo- sphere. Blow-by gas in the engine is constantly drawn into the crankcase, which is returned to the combus- tion chamber through the PCV (breather) hose, air cleaner and throttle body.
