DTC CONFIRMATION PROCEDURE

1.CHECK SELF DIAGNOSTIC RESULT

With CONSULT.

  1. Start engine and drive vehicle at approximately 21 km/h (13 MPH) or more for approximately 5 minutes.
  2. Perform self diagnostic result.

Diagnosis Procedure

CAUTION: Do not check between wheel sensor terminals.

1.CONFIRM DTC

With CONSULT

  1. Perform self-diagnostic result of ABS and record all active DTCs.
  2. Clear all DTCs.
  3. Perform DTC confirmation procedure.

2.INSPECT WHEEL SENSOR

Inspect the suspect wheel sensor for damage or deformation.

3.HARNESS AND CONNECTOR INSPECTION

  1. Disconnect ABS actuator and electric unit (control unit) connector E26 and wheel sensor connector of suspect wheel.
  2. Check harness, connectors and terminals for corrosion, deformation, disconnection, looseness or damage.

4.CHECK WHEEL SENSOR OUTPUT SIGNAL

  1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
  2. Turn on the ABS active wheel sensor tester power switch. 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.

5.CHECK WIRING HARNESS FOR SHORT TO VOLTAGE

  1. Turn ignition switch ON.
  2. Check voltage between wheel sensor harness connector terminals of suspect wheel and ground.

6.CHECK WIRING HARNESS FOR SHORT TO GROUND

  1. Turn ignition switch OFF.
  2. Check continuity between wheel sensor harness connector terminals of suspect wheel and ground.

11.CHECK WHEEL SENSOR INPUT VOLTAGE

  1. Connect ABS actuator and electric unit (control unit) connector E26.
  2. Turn ignition switch ON.
  3. Check voltage between suspect wheel sensor harness connector terminals.
