General Precautions

-Never disassemble VCM and DC/DC junction box.
-If the 12V battery is disconnected, the diagnostic information will be lost within 3 minutes.
-When connecting or disconnecting harness connectors into or from VCM, take care not to damage pin terminals (bend or break).
Check that there are not any bends or breaks on VCM pin terminal, when connecting harness connectors.





-After performing each TROUBLE DIAGNOSIS, perform DTC
confirmation procedure or Component Function Check.
The DTC should not be displayed in the DTC Confirmation
