C1115 WHEEL SENSOR

Description

INFOID:0000000001731109

When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current
signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).

DTC CONFIRMATION PROCEDURE

1.

CHECK SELF-DIAGNOSIS RESULTS

Check the self-diagnosis results.

Is above displayed on the self-diagnosis display?

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-41, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000001731111

CAUTION:

Do not check between wheel sensor terminals.

INSPECTION PROCEDURE

1.

CONNECTOR INSPECTION

Disconnect the ABS actuator and electric unit (control unit) connector E125 and wheel sensor of malfunction-
ing code. 
Check the 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-182, "Removal and Installation"

.

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 No.

2.

Check continuity between wheel sensor harness connector ter-
minals and ground.

Is the inspection result normal?

YES

>> GO TO 6

NO

>> Repair the circuit.

6.

CHECK WIRING HARNESS FOR OPEN CIRCUIT

1.

Check continuity between ABS actuator and electric unit (control unit) harness connector E125 and the
malfunctioning wheel sensor harness connector E18, E117, C10, or C11.

Is the inspection result normal?

YES

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

BRC-184, "Removal and Instal-

lation"

.

NO

>> Repair the circuit.
