Diagnosis Procedure

Regarding Wiring Diagram information, refer to "Wiring Diagram" [1][2]Antilock Brakes / Traction Control Systems.

CAUTION:
Do not check between wheel sensor terminals.

1. CONNECTOR INSPECTION

1.Disconnect ABS actuator and electric unit (control unit) connector E125 and wheel sensor connector of wheel with DTC.
2.Check terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES- GO TO 2.
NO- Repair or replace as necessary.

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 "Removal and Installation Front Wheel Sensor" Front Wheel Sensor or
"Removal and Installation Rear Wheel Sensor" Rear Wheel Sensor.

3. CHECK WHEEL BEARINGS

Check wheel bearing axial end play. Refer to "Inspection" Testing and Inspection (front) "Inspection" Inspection (rear).
Is the inspection result normal?
YES- GO TO 4.
NO- Repair or replace as necessary. Refer to "Removal and Installation" Removal and Installation (front) or "Removal and Installation" Removal and Installation (rear).

4. CHECK WIRING HARNESS FOR SHORT CIRCUIT

Check continuity between wheel sensor connector terminals and ground of wheel with DTC.





Is the inspection result normal?
YES- Replace the ABS actuator and electric unit (control unit). Refer to "Removal and Installation" Removal and Installation.
