C1107
C1105, C1106, C1107, C1108 WHEEL SENSOR-2Description
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.CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.
Is above displayed on the self-diagnosis display?
YES >> Proceed to diagnosis procedure. Refer to "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
CAUTION:
Do not check between wheel sensor terminals.
1.CHECK TIRES
Check air pressure, wear and size.
Are air pressure, wear and size within standard?
YES >> GO TO 2.
NO >> Adjust air pressure, or replace tire.
2.CHECK SENSOR AND SENSOR ROTOR
^ Check sensor rotor for damage.
^ Check wheel sensor for damage, disconnection or looseness.
Are the sensor and sensor rotor normal?.
YES >> GO TO 3.
NO >> Repair wheel sensor mount or replace sensor rotor. Then perform the self-diagnosis.
3.CHECK CONNECTOR
1. Turn ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Disconnect malfunctioning wheel sensor connector.
4. Check terminal to see if it is deformed, disconnected, loose, etc., Repair or replace it if any malfunction condition is found.
5. Reconnect connectors and then perform the self-diagnosis.
Is any item indicated on the self-diagnosis display?
YES >> GO TO 4.
NO >> Poor connection of connector terminal. Repair or replace connector.
4.CHECK WHEEL SENSOR HARNESS
1. Turn ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Disconnect malfunctioning wheel sensor connector.
4. Check continuity between terminals. (Also check continuity when steering wheel is turned right and left and when sensor harness inside the wheel house is moved.)
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace malfunctioning components.
5.CHECK WHEEL SENSOR POWER SUPPLY CIRCUIT
1. Disconnect malfunctioning wheel sensor connector.
2. Turn ignition switch ON.
3. Check voltage between wheel sensor harness connector power supply terminal and ground.
Is the inspection result normal?
YES >> Replace applicable wheel sensor.
NO >> Replace ABS actuator and electric unit (control unit).
Component Inspection
1.CHECK DATA MONITOR
On "DATA MONITOR", select "FR LH SENSOR", "FR RH SENSOR", "RR LH SENSOR", and "RR RH SENSOR", and check the vehicle speed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to diagnosis procedure. Refer to "Diagnosis Procedure".
Special Repair Requirement
1.ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
Always perform the "ST ANG SEN ADJUSTMENT" in "WORK SUPPORT", when replacing the ABS actuator and electric unit (control unit).
