Wheel Sensor System InspectionINFOID:0000000005928484
INSPECTION PROCEDURE
1.CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E33 and wheel sensor of malfunctioning
code.
Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 2.
NG >> 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 s ensor tester detect a signal?
YES >> GO TO 3.
NO >> Replace the wheel sensor. Refer to BRC-86, "
Removal and Installation".
3.CHECK TIRES
Check for inflation pressure, wear and size of each tire. Refer to WT-28, "
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 FA X - 6 , "
On-Vehicle Inspection and Service" or RAX-6, "On-Vehi-
cle Inspection and Service".
OK or NG
OK >> GO TO 5.
NG >> Repair or replace as necessary. Refer to FAX-6, "
Removal and Installation" (front) or RAX-6,
"Removal and Installation" (rear).
5.CHECK WIRING HARNESS FOR SHORT CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connec- tor and wheel sensor connector of malfunction code No.
3. Check continuity between wheel sensor harness connector ter- minals and ground.
OK or NG
OK >> GO TO 6.
NG >> Repair the circuit.
6.CHECK WIRING HARNESS FOR OPEN CIRCUIT Continuity should not exist.

Yaw Rate/Side/Decel G Sensor System InspectionINFOID:0000000005928488
CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF may
cause the yaw rate/side/decel G sensor system to indi cate a problem. However this is not a problem if
normal operation can be resumed after restarting the engine.
INSPECTION PROCEDURE
1.SELF-DIAGNOSIS RESULT CHECK
Check self-diagnosis results.
CAUTION:
When on a turntable, such as at a parking structure entrance, or when on a moving object with the
engine running, the VDC OFF indicator lamp migh t turn on and the self-diagnosis using the CONSULT-
III the yaw rate sensor system might be displayed, but in this case there is no problem with the yaw
rate sensor system. As soon as the vehicle leaves the turntable or moving object, restart the engine to
return the system to normal.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> Inspection End.
