PROCEDURE


  1. CHECK DTC OUTPUT (TVD)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Enter the following menus: Chassis / TVD / Trouble Codes.

    4. Check for DTCs.


      Chassis > TVD > Trouble Codes
      Result
      Result Proceed to
      DTC C2A08 or DTC C2A09 only is output. A
      DTCs other than DTC C2A08 and DTC C2A09 are output. B
      DTCs are not output. C

      1. Turn the engine switch off.
