INSPECTION PROCEDURE

Tech Tips

After the repair, plug-in charge the vehicle for 1 minute or more and disconnect the electric vehicle charger cable assembly. And then turn the power switch on (IG) and wait for 10 seconds or more to check that no DTCs are output.

PROCEDURE


  1. CHECK DTC OUTPUT (HEALTH CHECK)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: System Select / Health Check.

    4. Check if DTCs are output.

      Result
