CHECK WHEEL SENSOR HARNESS
1.
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.)
Measurement terminal for power supply circuit
Measurement terminal for signal circuit
2.
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.
REPLACE WHEEL SENSOR
1.
Replace wheel sensor.
2.
Erase self-diagnosis results for “ABS” with CONSULT-III.
3.
Turn the ignition switch OFF.
4.
Turn the ignition switch ON.
CAUTION:
Never start the engine.
5.
Perform self-diagnosis for “ABS” with CONSULT-III.
Is DTC “C1101”, “C1102”, “C1103” or “C1104” detected?
YES
>> Replace ABS actuator and electric unit (control unit).
NO
>> INSPECTION END

C1105, C1106, C1107, C1108 WHEEL SENSOR
Description
INFOID:0000000005234503
When the sensor rotor rotates, the magnetic field changes. Wheel sensor 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. Refer to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000005234505
CAUTION:
Never check between wheel sensor terminals.
1.
CHECK TIRES
Check air pressure, wear and size. Refer to
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace error-detected parts.
2.
CHECK SENSOR AND SENSOR ROTOR
• Check sensor rotor for damage.
• Check wheel sensor for damage, disconnection or looseness.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair wheel sensor mount or replace sensor rotor. Then erform self-diagnosis for "ABS" with
CONSULT-III.
3.
CHECK CONNECTOR
1.
Turn the ignition switch OFF.
2.
Disconnect ABS actuator and electric unit (control unit) harness connector.
