C1105, C1106, C1107, C1108 WHEEL SENSOR-2
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"
.
3.
CHECK TIRES
Check for inflation pressure, wear and size of each tire.
Are tire pressure and size correct and is tire wear within specifications?
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"
"On-Vehicle Inspection and Service"
(rear).
Is the inspection result normal?
YES
>> GO TO 5
NO
>> Repair or replace as necessary. Refer to
FAX-7, "Removal and Installation"
(front) or
(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 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.
Continuity should not exist.
