INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.





Is above displayed on the self-diagnosis display?
YES >> GO TO 2.
NO >> INSPECTION END

YES >> GO TO 3.
NO >>
^ Adjust air pressure, or replace tire.
^ Perform the self-diagnosis, and make sure that the result shows NO DTC IS DETECTED. CONSULT-II / Self-Diagnosis

3. CHECK SENSOR AND SENSOR ROTOR
^ Check sensor rotor for damage.
^ Check wheel sensor for damage, disconnection or looseness.
OK or NG
OK >> GO TO 4.
NG >>
^ Repair wheel sensor mount or replace sensor rotor. Then perform the self-diagnosis.
^ Perform the self-diagnosis, and make sure that the result shows NO DTC IS DETECTED. CONSULT-II / Self-Diagnosis

4. CHECK CONNECTOR
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E30 and malfunctioning wheel sensor connector E41(FR-RH), E59(FR-LH), B101(RR-RH), B102(RR-LH). Check terminal to see if it is deformed, disconnected, loose, etc., Repair or replace it if any malfunction condition is found.
2. Reconnect connectors and then perform the self-diagnosis. CONSULT-II / Self-Diagnosis
OK or NG
OK >> INSPECTION END
NG >> GO TO 5.

5. CHECK WHEEL SENSOR HARNESS





1. Turn ignition switch OFF and disconnect malfunctioning wheel sensor connector E41(FR-RH), E59(FR-LH), B101(RR-RH), B102(RR-LH) and ABS actuator and electric unit (control unit) connector E30.





2. Check continuity between terminals. (Also check continuity when steering wheel is turned right and left and when sensor harness inside the wheel house is moved.) Power supply circuit Yes Signal circuit Yes Ground circuit No
OK or NG
OK >> GO TO 6.
NG >> Repair or replace malfunctioning components. Perform the self-diagnosis, and make sure that the result shows NO DTC IS DETECTED. CONSULT-II / Self-Diagnosis

6. 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. CONSULT-II / Self-Diagnosis
Is above displayed on the self-diagnosis display?
