CHECK SELF-DIAGNOSTIC RESULTS (2)
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
1. OK : Poor connection of connectors. Repair or replace suspect connector. Perform self-diagnosis again.
2. NO : GO TO 3.
CHECKING 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 E118 and VDC actuator (pressure sensor) harness connector E50.
