Diagnosis Procedure

CAUTION:
For wheel sensor, never check between terminals.
1.CHECK TIRE
1. Turn the ignition switch OFF.
2. Check tire air pressure, wear and size. [1][2]Specifications.
Is the inspection result normal?
YES - GO TO 2.
NO - Adjust air pressure. Or replace tire. [1][2]Specifications.
2.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY SYSTEM
Check ABS actuator and electric unit (control unit) power supply system. Power Supply And Ground Circuit.
Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace error-detected parts.
3.CHECK WHEEL SENSOR HARNESS
1. Disconnect ABS actuator and electric unit (control unit) harness connector.
2. Disconnect wheel sensor harness connector.
3. Check continuity between ABS actuator and electric unit (control unit) harness connector and wheel sensor harness connector. (Check continuity when steering wheel is steered to RH and LH, or center harness in wheel housing is moved.)










4. Check continuity between ABS actuator and electric unit (control unit) harness connector and the ground.





Is the inspection result normal?
YES - GO TO 4.
NO - Repair or replace error-detected parts.
4.CHECK WHEEL SENSOR
Check wheel sensor for damage, disconnection or looseness.
- Front wheel sensor: Exploded View.
- Rear wheel sensor: Exploded View.
Is the inspection result normal?
YES - GO TO 5.
NO - Repair wheel sensor mount or replace wheel sensor.
- Front wheel sensor: Removal And Installation.
- Rear wheel sensor: Removal And Installation.
5.CHECK SENSOR ROTOR
Check sensor rotor for damage, disconnection or looseness.
- Front sensor rotor: Front Sensor Rotor.
- Rear sensor rotor: Rear Sensor Rotor.
Is the inspection result normal?
YES - GO TO 6.
NO - Repair sensor rotor mount or replace sensor rotor.
- Front sensor rotor: Front Sensor Rotor.
- Rear sensor rotor: Rear Sensor Rotor.
6.CHECK TERMINAL
- Check ABS actuator and electric unit (control unit) pin terminals for damage or loose connection with harness connector.
- Check each wheel sensor pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES - GO TO 7.
NO - Repair or replace error-detected parts.
7.REPLACE WHEEL SENSOR
With CONSULT-III.
1. Connect ABS actuator and electric unit (control unit) harness connector.
2. Replace wheel sensor. Removal And Installation (front), Removal And Installation (rear).
3. Erase Self-diagnosis result for "ABS".
4. Start the engine. Drive the vehicle at vehicle speed of approx. 30 km/h for approx. 1 minute.
5. Perform self-diagnosis for "ABS".
Is DTC "C1115" detected?
YES - Replace ABS actuator and electric unit (control unit). Removal And Installation.
NO - INSPECTION END
