Tech Tips

If a CAN communication DTC is output, perform troubleshooting for that DTC first.

PROCEDURE


  1. CHECK DTC OUTPUT (CAN COMMUNICATION SYSTEM)


    1. Check for DTCs of the CAN communication system.

  2. READ VALUE USING GTS (G SENSOR)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List.

      • Vehicle on level ground: 2.31 V to 2.69 V

      • Decelerating: 1.88 V to 2.5 V

      • Accelerating: 2.5 V to 3.11 V

      • G sensor malfunction: Set to 1.87 V

      • Communication malfunction: Set to 1.87 V
