DTC CONFIRMATION PROCEDURE


1. CHECK SELF DIAGNOSTIC RESULT

With CONSULT.
1.Start engine and drive vehicle at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
2.Perform self diagnostic result.
Is DTC C1101, C1102, C1103 or C1104 detected?
YES- Proceed to diagnosis procedure. Refer to "Diagnosis Procedure" .
NO- Inspection End.


Diagnosis Procedure

Regarding Wiring Diagram information, refer to "Wiring Diagram" Electrical Diagrams.

CAUTION:
Do not check between wheel sensor terminals.

1. CONNECTOR INSPECTION

1.Disconnect ABS actuator and electric unit (control unit) connector E54 and wheel sensor connector of wheel with DTC.
2.Check connectors and terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES- GO TO 2.
NO- Repair or replace as necessary.

2. 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.
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" Removal And Installation - Front Wheel Sensor or
"Removal and Installation Rear Wheel Sensor" Removal And Installation - Rear Wheel Sensor.

3. CHECK WIRING HARNESS FOR OPEN CIRCUIT

Check continuity between ABS actuator and electric unit (control unit) connector E54 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 "Removal and Installation" Removal And Installation.
NO- Repair the circuit.
