C1106

C1105, C1106, C1107, C1108 WHEEL SENSOR





Description
When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).

DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
1. Start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
2. Perform self-diagnosis for "ABS" with CONSULT-III.
Is DTC "C1105", "C1106", "C1107", or "C1108" detected?
YES - Proceed to diagnosis procedure. C1105.
NO - INSPECTION END




Diagnosis Procedure

CAUTION:
Never check between wheel sensor harness connector terminals.
1.CHECK TIRES
Check air pressure, wear and size. Specifications.
Is the inspection result normal?
YES - GO TO 2.
NO - Adjust air pressure or replace error-detected parts.
2.CHECK WHEEL SENSOR
Check wheel sensor for damage, disconnection or looseness.
- Front: Exploded View.
- Rear: Exploded View.
Is the inspection result normal?
YES - GO TO 3.
NO - Repair wheel sensor mount or replace wheel sensor.
- Front: Exploded View.
- Rear: Exploded View.
3.CHECK SENSOR ROTOR
Check sensor rotor for damage, disconnection or looseness.
- Front: Removal And Installation.
- Rear: Removal And Installation.
Is the inspection result normal?
YES - GO TO 4.
NO - Repair wheel sensor mount or replace sensor rotor.
- Front: Removal And Installation.
- Rear: Removal And Installation.
4.CHECK WHEEL SENSOR HARNESS
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) harness connector and wheel sensor harness connector.
3. Check the continuity between ABS actuator and electric unit (control unit) harness connector and wheel sensor harness connector. (Also check continuity when steering wheel is turned right and left and when sensor harness inside the wheel house is moved.)










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





Is the inspection result normal?
YES - GO TO 5.
NO - Repair or replace error-detected parts.
5.CHECK TERMINALS AND HARNESS CONNECTORS
1. Check ABS actuator and electric unit (control unit) pin terminals for damage or loose connection with harness connector.
2. Check each wheel sensor pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES - GO TO 6.
NO - Repair or replace error-detected parts.
6.REPLACE WHEEL SENSOR
1. Replace wheel sensor.
2. Erase self-diagnosis results for "ABS" with CONSULT-III.
3. Start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
4. Perform self-diagnosis for "ABS" with CONSULT-III.
Is DTC "C1105", "C1106", "C1107" or "C1108" detected?
YES - Replace ABS actuator and electric unit (control unit). Exploded View
NO - INSPECTION END




Special Repair Requirement
1.ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
Always perform the neutral position adjustment for the steering angle sensor, when replacing the ABS actuator and electric unit (control unit) or steering angle sensor and removing steering angle sensor. Special Repair Requirement
