Is the above displayed in the self-diagnosis item?

1. YES: GO TO 2.
2. NO: Inspection End

1. Disconnect the VDC/TCS/ABS control unit connector and check the terminal for deformation, disconnection, looseness, and so on. If there is an error, repair or replace the terminal.
2. Securely reconnect the connector and Re-conduct self-diagnosis.

OK or NG 

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

1. Disconnect the VDC/TCS/ABS control unit connector.
2. With the ignition switch turned on and off, check the voltage and continuity between the VDC/TCS/ABS control unit harness connector and the ground.
