YES

>> GO TO 3

NO

>> Replace the wheel sensor. Refer to 

BRC-69, "Removal and Installation"

.

3.

CHECK TIRES

Check the inflation pressure, wear and size of each tire.

Check wheel bearing axial end play. Refer to 

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

 (front) or 

RAX-6,

"Rear Axle Bearing"

 (rear).

Is the inspection result normal?

YES

>> GO TO 5

NO

>> Repair or replace as necessary. Refer to 

FAX-8, "Removal and Installation"

 (front) or 

RAX-12,

"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?

Continuity should not exist.

Description

INFOID:0000000005275053

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).
