CHECK SELF-DIAGNOSTIC RESULTS

Check the self-diagnostic results.

SELF-DIAGNOSTIC RESULTS TABLE

Self-diagnostic results
FR RH SENSOR -1, -2
FR LH SENSOR -1, -2
RR RH SENSOR -1, -2
RR LH SENSOR -1, -2

Is above displayed in the self-diagnosis display item?

YES: GO TO 2.

NO: INSPECTION END.

CHECK TIRE
Check air pressure, wear and size.

Are air pressure, wear, and size within standards?

YES: GO TO 3.

NO: Adjust air pressure or replace tire.
CHECK CONNECTOR
Turn ignition switch OFF and disconnect VDC/TCS/ABS control unit connector and connector of wheel sensor where malfunction was detected. Check terminals for deformation and connectors for poor contact. Then reconnect connectors. Also make sure interference with other parts has not cut wheel sensor cables.

Drive vehicle at 30 km/h (19 MPH) or above for at least 1minute. Does ABS warning lamp turn off?

YES: INSPECTION END

NO: GO TO 4.
CHECK SENSOR ROTOR
Check sensor rotor teeth and surface of rubber for damage.

OK or NG

OK: GO TO 5.

NG: Replace sensor rotor.

CHECK WHEEL SENSOR HARNESS

Turn ignition switch OFF and disconnect malfunctioning wheel sensor connector and VDC/TCS/ABS control unit connector.

Check the continuity between terminals. (Also check the continuity when steering wheel is turned right and left and when sensor harness inside wheel well is moved.)

WHEEL SENSOR HARNESS

	Power supply circuit		Signal circuit		Ground circuit
Wheel	VDC/TCS/ABS control unit	Wheel sensor	VDC/TCS/ABS control unit	Wheel sensor	VDC/TCS/ABS control unit (Signal)	VDC/TCS/ABS control unit (Ground)
Front RH	16	1	15	2	15, 16	-
Front LH	10	1	8	2	8, 10
Rear RH	12	1	11	2	11, 12
Rear LH	14	3	13	4	13, 14

Power supply circuit: Continuity should exist .

Signal circuit: Continuity should exist .

Ground circuit: Continuity should not exist .

OK or NG

OK: GO TO 6.

NG: Repair or replace harness and connector that have malfunction.

CHECK WHEEL SENSOR
1. Replace wheel sensor that resulted in malfunction by self-diagnosis.
2. Reconnect connectors, drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute, and then perform self-diagnosis.
Is above displayed on self-diagnosis display?

OK: Wheel sensor has malfunction.

NG :
- Replace VDC/TCS/ABS control unit.
- Perform to self-diagnosis again, and make sure that the result shows "NO DTC IS DETECTED. FURTHER TESTING MAY BE REQUIRED."
