6. CHECK SELF-DIAGNOSIS RESULT ITEM 1
Conduct self-diagnosis of the VDC/TCS/ABS control unit.
Are self-diagnosis items displayed?
YES >> Check the corresponding items, make repairs, and re-conduct the VDC/TCS/ABS control unit self-
diagnosis.
NO >> GO TO 7.
7. CHECK CONNECTOR
1. Disconnect the VDC/TCS/ABS control unit and the ECM connectors, check the terminals for deformation,
disconnection, looseness, and so on. If there is an error, repair or replace the connector.
