Description

INFOID:0000000001731252

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).

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-83, "Removal and Installation"

.
