Check self-diagnosis results.

Is above displayed in self-diagnosis display item? 

1. YES: GO TO 2.
2. NO: INSPECTION END.

1. Disconnect VDC actuator connector E21 and VDC/TCS/ABS control unit connector, check terminals for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace terminal.
2. Reconnect connectors and Re-perform VDC/TCS/ABS control unit self-diagnosis.

OK or NG 

1. OK: Connector terminal contact is loose, damaged, open or shorted.
2. NG: GO TO 3.

1. Disconnect VDC actuator connector E21 and VDC/TCS/ABS control unit connector.
