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 C1115 detected?

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-69, "Diagnosis Procedure"

.

NO

>> Inspection End.

Diagnosis Procedure

INFOID:0000000009177280

Regarding Wiring Diagram information, refer to 

BRC-44, "Wiring Diagram"

.

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.

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 

BRC-118, "Removal and Installation - Front Wheel Sensor"

 or

BRC-120, "Removal and Installation - Rear Wheel Sensor"

.

3.

CHECK TIRES

Check the inflation pressure, wear and size of each tire.
Is the inspection result normal?

>> GO TO 4.

NO

>> Adjust tire pressure, or replace tire(s). 

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

>> GO TO 5.

NO

>> Repair the circuit.

5.

CHECK WIRING HARNESS FOR OPEN CIRCUIT

Check continuity between ABS actuator and electric unit (control unit) connector E125 and wheel sensor con-

nector of wheel with DTC.

Is the inspection result normal?

YES

>> Replace the ABS actuator and electric unit (control unit). Refer to 

BRC-123, "Removal and Instal-

lation"

.

NO

>> Repair the circuit.
