INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.





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

2. CHECK CONNECTOR
1. Turn ignition switch OFF and disconnect VDC actuator (pressure sensor) connector and VDC/TCS/ABS control unit connector. Then reconnect them securely.
2. Perform VDC/TCS/ABS control unit self-diagnosis again.
OK or NG
OK >> Poor connection of connectors. Repair or replace suspect connector. Perform self-diagnosis again.
NO >> GO TO 3.

3. CHECK PRESSURE SENSOR CIRCUIT





1. Turn ignition switch OFF and disconnect VDC actuator (pressure sensor) connector and VDC/TCS/ABS control unit connector.
2. Check continuity between VDC/TCS/ABS control unit harness connector M93 and VDC actuator (pressure sensor) harness connector E50.





OK or NG
OK >> GO TO 4.
NG >> Open or short in harness. Repair or replace the suspect harness.

4. CHECK PRESSURE SENSOR
1. Connect VDC actuator (pressure sensor) connector and VDC/TCS/ABS control unit connector.
2. Check pressure sensor value on DATA MONITOR.





OK or NG
OK >> Perform VDC/TCS/ABS control unit self-diagnosis again.
NG >> Pressure sensor malfunction. Replace VDC actuator (inside pressure sensor).
