  • Page 167: Fuse

    FI SYSTEM DIAGNOSIS • When connecting meter probe from the terminal side of the coupler (connection from harness side not being possible), 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 168 FI SYSTEM DIAGNOSIS • 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 169: Electrical Circuit Inspection Procedure

    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 170 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 171 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 172: Using Testers

    FI SYSTEM DIAGNOSIS USING TESTERS • Use the Suzuki multi-circuit tester set (09990-25008). • 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.
  • Page 174: Compensation Of Injection Time (Volume)

    4-10 FI SYSTEM DIAGNOSIS COMPENSATION OF INJECTION TIME (VOLUME) The following different signals are output from the respective sensors for compensation of the fuel injection time (volume).

  • Page 216: Fuel System

    FUEL SYSTEM AND THROTTLE BODY FUEL SYSTEM FUEL DELIVERY SYSTEM The fuel delivery system consists of the fuel tank, fuel pump, fuel filters, fuel feed hose, fuel delivery pipe (including fuel injectors) and fuel pressure regulator. There is no fuel return hose. The fuel in the fuel tank is pumped up by the fuel pump and pressurized fuel flows into the injector installed in the fuel delivery pipe.
  • Page 217: Fuel Pump

    FUEL SYSTEM AND THROTTLE BODY FUEL PUMP The electric fuel pump is mounted at the bottom of the fuel tank, which consists of the armature, magnet, impeller, brush, check valve and relief valve. The ECM controls its ON/OFF operation as controlled under the FUEL PUMP CONTROL SYSTEM.
  • Page 218 FUEL SYSTEM AND THROTTLE BODY When the impeller is driven by the motor, pressure differential occurs between the front part and the rear part of the blade groove as viewed in angular direction due to fluid friction. This process continuously takes place causing fuel pressure to be built up.
  • Page 219: Fuel Pressure Regulator

    FUEL SYSTEM AND THROTTLE BODY FUEL PRESSURE REGULATOR The fuel pressure regulator consists of the spring and valve. It keeps absolute fuel pressure of 300 kPa (3.0 kgf/cm , 43 psi) to be applied to the injector at all times. When the fuel pressure rises more than 300 kPa (3.0 kgf/cm , 43 psi), the fuel pushes the valve in the regu- lator open and excess fuel returns to the fuel tank.
  • Page 220: Fuel Pump Control System

    FUEL SYSTEM AND THROTTLE BODY FUEL PUMP CONTROL SYSTEM When the ignition switch is turned on, current from the battery flows to the fuel pump motor through the side- stand relay and the fuel pump relay causing the motor to turn. Since the ECM has a timer function, the fuel pump motor stops turning in three seconds after the switch has been turned on.

    13-68 DL650K7/AK7 (’07-MODEL) INTRODUCTION OF ABS (For DL650A) FRONT AND REAR WHEEL SPEED SENSORS Wheel speed sensor consists of wheel speed sensor 1 and sensor rotor 2. ABS CONTROL UNIT ABS control unit ABS control unit calculates signals input from each one of front and rear wheel speed sensors, monitors the slipping conditions of the wheels and, at the same time, sends control signal to Hydraulic Unit (HU).
  • Page 573 DL650K7/AK7 (’07-MODEL) 13-69 ABS CONTROL UNIT CALCULATING PROCESS The ABS controls and its calculations, in addition to the self-diagnosing and the fail-safe processes, occur during the ABS control unit calculating process. In addition, if a malfunction is detected by the self-diagnosis function, the brake stops being controlled by the ABS and a diagnostic trouble code is stored.
  • Page 574 13-70 DL650K7/AK7 (’07-MODEL) HYDRAULIC UNIT (HU) The hydraulic unit operates the solenoid valves based upon the signal which is output from the ABS control unit. The brake fluid pressure is then adjusted accordingly. The hydraulic unit controls the front and rear brake systems individually by operating separate components for the front and the rear, except for the pump drive motor, which is shared by both systems.

    DL650K7/AK7 (’07-MODEL) 13-71 FAIL-SAFE FUNCTION If malfunction occurs in the ABS electric system, this sets valve relay OFF.

  • Page 577 DL650K7/AK7 (’07-MODEL) 13-73 BATTERY • Only use a fully charged battery. • In order to prevent damage to the ABS control unit etc., be sure to connect the battery properly. • Never disconnect the battery or any other lead wires while the engine is running.
  • Page 578 • Only use the specified tires. TESTER 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. • Since the resistance may differ depending on the tester used and the temperature, the resistance should be set to the spec- ification.

  • Page 586 13-82 DL650K7/AK7 (’07-MODEL) INFORMATION GATHERING To properly diagnose a malfunction, one must not make guesses or assumptions about the circumstances that caused it. Proper diagnosis and repair require duplicating the situation in which the malfunction occurred. If a diagnosis is made without duplicating the malfunction, even an experienced service technician may make a misdiagnosis and not perform the servicing procedure correctly, resulting in the malfunction not being repaired.
