C1101, C1102, C1103, C1104 WHEEL SENSOR-1 BRC-29 < COMPONENT DIAGNOSIS > [VDC/TCS/ABS] C D E G H I J K L M A B BRC N O P 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. 3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal. 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-114, "Removal and Installation" 3. CHECK TIRES Check the inflation pressure, wear and size of each tire. YES >> GO TO 4 NO >> Adjust tire pressure or replace tire(s). 4. CHECK WHEEL BEARINGS Check wheel bearing axial end play. Refer to FAX-6, "On-Vehicle Inspection and Service" "On-Vehicle Inspection and Service" (rear). Is the inspection result normal? YES >> GO TO 5 NO >> Repair or replace as necessary. Refer to FAX-7, "Removal and Installation" (rear). 5. CHECK WIRING HARNESS FOR SHORT CIRCUIT 1. Disconnect ABS actuator and electric unit (control unit) connec- tor and wheel sensor connector of malfunction code. 2. Check continuity between wheel sensor connector terminals and ground. Is the inspection result normal? YES >> GO TO 6 NO >> Repair the circuit. 6. CHECK WIRING HARNESS FOR OPEN CIRCUIT Check continuity between ABS actuator and electric unit (control unit) connector and the malfunctioning wheel sensor connector. Is the inspection result normal? Continuity should not exist.
