Wheel Sensor System
First use CONSULT-II self-diagnostic results to determine positions of malfunctioning wheel sensors. Then inspect parts and determine which parts to replace.
Do not measure the resistance value and also voltage between sensor terminal with tester etc., because sensor is an active sensor.
Do not expand terminal of connector with a tester terminal stick, when it does the inspection with tester.
CHECK SELF-DIAGNOSTIC RESULTS Check the self-diagnostic results.
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 1 minute. 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.)
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
Replace wheel sensor that resulted in malfunction by self-diagnosis.
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.
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.
