C1115 WHEEL SENSOR

C1115 WHEEL SENSOR

Description

INFOID:0000000009883631

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-42, "Diagnosis Procedure"

.

NO

>> Inspection End

Diagnosis Procedure

INFOID:0000000009883633

Regarding Wiring Diagram information, refer to 

BRC-92, "Wiring Diagram"

.

CAUTION:

Do not check between wheel sensor terminals.

1.

CONNECTOR INSPECTION

1. Disconnect the ABS actuator and electric unit (control unit) connector and wheel sensor of malfunctioning

code. 

2. 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-113, "Removal and Installation"

.

CHECK TIRES

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

YES

>> GO TO 4

NO

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

4.

CHECK WHEEL BEARINGS

Check wheel bearing axial end play. Refer to 

FAX-5, "On-Vehicle Inspection and Service"

 (front) or 

RAX-5,

"On-Vehicle Inspection"

 (rear).

Is the inspection result normal?

YES

>> GO TO 5

NO

>> Repair or replace as necessary. Refer to 

FAX-6, "Removal and Installation"

 (front) or 

RAX-7,

"Removal and Installation"

 (rear).

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 connector terminals

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) connector and the malfunctioning

wheel sensor connector.

Is the inspection result normal?

YES

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

BRC-116, "Removal and Instal-

lation"

.

NO

>> Repair the circuit.
