6. The self-diagnostic results are displayed. • When “NO DTC IS DETECTED” is displayed, check the ABS warning lamp, SLIP indicator lamp and
VDC OFF indicator lamp.
7. Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. Start engine and drive at approximately 30 km /h (19 MPH) for approximately 1 minute.
CAUTION:
• When a wheel sensor “short-circuit” is detected, if the vehicle is not driven at 30 km/h (19 MPH)
for at least 1 minute, the ABS warn ing lamp will not turn off even if the malfunction is repaired.
9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start the engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE” in order on the CONSULT-III screen to erase the error memory.
If “ABS” is not indicated, go to GI-36, "
CONSULT-III Data Link Connector (DLC) Circuit".
CAUTION:
If the error memory is not erased, re -conduct the operation from step 5.
11. For the final inspection, drive at approximately 30 km/h (19 MPH) for approximately 1 minute and confirm
that the ABS warning lamp, SLIP indicator lamp, and VDC OFF indicator lamp are off.

Wheel Sensor System InspectionINFOID:0000000005612159
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.
