    5. If OK, check harness for short to ground and short to power.
    6. Reinstall any part removed.

    OK or NG 

    OK: GO TO 4.

    NG: Replace open circuit or short to ground and short to power in harness or connectors.

  4. DETECT MALFUNCTIONING ITEM 

    Check the following.

    OK or NG 

    OK: Replace the control valve with TCM. Refer to "CONTROL VALVE WITH TCM AND A/T FLUID TEMPERATURE SENSOR 2 ".

    NG: Repair or replace damaged parts.

  5. CHECK DTC 

    Perform "DTC CONFIRMATION PROCEDURE ".
