Component Function Check
1.CHECK VDC OFF SWITCH OPERATION
Check that VDC OFF indicator lamp in combination meter turns ON/OFF when VDC OFF switch is operated.
Is the inspection result normal?
YES - INSPECTION END
NO - Proceed to diagnosis procedure. SEE Diagnosis Procedure.




Diagnosis Procedure

NOTE:
VDC OFF switch is integrated in SNOW MODE / TOW MODE / VDC OFF switch assembly (2WD models) or
4WD switch assembly (4WD models).
1.CHECK VDC OFF SWITCH CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) harness connector.
3. Disconnect SNOW MODE / TOW MODE / VDC OFF switch assembly (2WD models) or 4WD switch assembly (4WD models) harness connector.
4. Check continuity between ABS actuator and electric unit (control unit) harness connector and SNOW
MODE / TOW MODE / VDC OFF switch assembly (2WD models) or 4WD switch assembly (4WD models) harness connector.





*1: SNOW MODE / TOW MODE / VDC OFF switch assembly (2WD models)
*2: 4WD switch assembly (4WD models)
5. Check continuity between ABS actuator and electric unit (control unit) harness connector terminal and ground.





Is the inspection result normal?
YES - GO TO 2.
NO - Repair or replace error-detected parts.
2.CHECK VDC OFF SWITCH GROUND CIRCUIT
Check continuity between SNOW MODE / TOW MODE / VDC OFF switch assembly (2WD models) or 4WD switch assembly (4WD models) harness connector terminal and ground.





*1: SNOW MODE / TOW MODE / VDC OFF switch assembly (2WD models)
*2: 4WD switch assembly (4WD models)
Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace error-detected parts.
3.CHECK VDC OFF SWITCH
Check VDC OFF switch. SEE Component Inspection.
Is the inspection result normal?
YES - GO TO 4.
NO - Replace VDC OFF switch. Service and Repair.
4.CHECK VDC OFF SWITCH SIGNAL
With CONSULT-III.
1. Connect ABS actuator and electric unit (control unit) harness connector.
2. Connect SNOW MODE / TOW MODE / VDC OFF switch assembly (2WD models) or 4WD switch assembly (4WD models) harness connector.
3. Select "ABS", "DATA MONITOR" and "OFF SW" according to this order. Check VDC OFF switch signal.





Is the inspection result normal?
YES - INSPECTION END
NO - GO TO 5.
5.CHECK TERMINAL
- Check ABS actuator and electric unit (control unit) pin terminals for damage or loose connection with harness connector.
- Check SNOW MODE / TOW MODE / VDC OFF switch assembly (2WD models) or 4WD switch assembly
(4WD models) pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES - Replace ABS actuator and electric unit (control unit). Service and Repair.
NO - Repair or replace error-detected parts.
