DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAGNOSTIC RESULT
With CONSULT.
Is DTC C1101, C1102, C1103 or C1104 detected? YES >> Proceed to diagnosis procedure. Refer to BRC-74, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis Procedure
Regarding Wiring Diagram information, refer to BRC-57, "Wiring Diagram".
1.CONFIRM DTC
With CONSULT
Does DTC C1101, C1102, C1103 or C1104 reset? YES >> GO TO 2.
NO >> Refer to GI-41, "Intermittent Incident".
2.INSPECT WHEEL SENSOR
Inspect the suspect wheel sensor for damage or deformation.
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace as necessary.
3.HARNESS AND CONNECTOR INSPECTION
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace as necessary.
4.CHECK WHEEL SENSOR OUTPUT SIGNAL
NOTE: The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the battery in the ABS active wheel sensor tester before proceeding.
NOTE: If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and retest.
Does the ABS active wheel sensor tester detect a signal? YES >> GO TO 5.
NO >> Replace the wheel sensor. Refer to BRC-132, "FRONT WHEEL SENSOR : Removal and Installation" or BRC-134, "REAR WHEEL SENSOR : Removal and Installation".
5.CHECK WIRING HARNESS FOR SHORT TO VOLTAGE
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair the circuit.
6.CHECK WIRING HARNESS FOR SHORT TO GROUND
Is the inspection result normal? YES >> GO TO 7.
NO >> Repair the circuit.
7.CHECK WIRING HARNESS FOR SHORT BETWEEN CIRCUITS
Check continuity between wheel sensor harness connector terminals of suspect wheel.
Is the inspection result normal? YES >> GO TO 8.
NO >> Repair the circuit.
8.CHECK WIRING HARNESS FOR OPEN CIRCUIT
Check continuity between ABS actuator and electric unit (control unit) harness connector E125 and harness connector of suspect wheel sensor.
Is the inspection result normal? YES >> GO TO 9.
NO >> Repair the circuit.
9.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> GO TO 10.
NO >> Check the following:
10.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 11.
NO >> Repair or replace malfunctioning components.
11.CHECK WHEEL SENSOR INPUT VOLTAGE
Is the inspection result normal? YES >> Replace wheel sensor. Refer to BRC-132, "FRONT WHEEL SENSOR : Removal and Installation" or BRC-134, "REAR WHEEL SENSOR : Removal and Installation". Then, GO TO 12.
NO >> Replace ABS actuator and electric unit (control unit). Refer to BRC-136, "Removal and Installation".
12.CONFIRM REPAIR
With CONSULT
Does DTC C1105, C1106, C1107 or C1108 reset? YES >> Replace ABS actuator and electric unit (control unit). Refer to BRC-136, "Removal and Installation".
NO >> Inspection End.
