Is the above displayed in the self-diagnosis display items?

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

1. Disconnect VDC actuator (pressure sensor) connector and VDC/TCS/ABS control unit connector, check the terminals for deformation, disconnection, looseness, and so on. If there is an error, repair or replace the terminal.
2. Reconnect the connectors and Re-conduct VDC/TCS/ABS control unit self-diagnosis.

OK or NG 

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

1. Turn ignition switch OFF and disconnect VDC actuator (pressure sensor) connector and VDC/TCS/ABS control unit connector.

OK or NG 

1. OK: GO TO 4.
2. NG: If the open or short in harness, repair or replace the harness.

1. Connect pressure sensor and VDC/TCS/ABS control unit connectors.
2. Use "Data Monitor" to check the pressure sensor value.

OK or NG 

1. OK: Inspection End
2. NG: If the pressure sensor is damaged or malfunctioning, replace the VDC actuator (pressure sensor it built in).
