With CONSULT.
Is DTC C1101, C1102, C1103 or C1104 detected?
YES >> Proceed to diagnosis procedure. Refer to BRC "Diagnosis Procedure".
NO >> Inspection End.
Regarding Wiring Diagram information, refer to BRC "Wiring Diagram".
CAUTION: Do not check between wheel sensor terminals.
1.CONNECTOR INSPECTION
Is the inspection result normal?
YES >> GO TO 2
NO >> Repair or replace as necessary.
2.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 3
NO >> Replace the wheel sensor. Refer to BRC "FRONT WHEEL SENSOR : Removal and Installation" (front) or BRC "REAR WHEEL SENSOR : Removal and Installation" (rear).
3.CHECK WIRING HARNESS FOR OPEN CIRCUIT

connector E33 and wheel sensor connector
of wheel with DTC.

Is the inspection result normal?
YES >> Replace the ABS actuator and electric unit (control unit). Refer to BRC "Removal and Installation".
NO >> Repair the circuit.
