      1. Open the driver side door.

      2. Put the vehicle into its initial condition Click here.

      3. Insert the key into the ignition key cylinder and leave it in the LOCK position.

      4. Push the driver door lock knob down to the LOCK position.

      5. Perform the following operations within 5 seconds:


        • Pull the driver lock knob up to the UNLOCK position.

        • Push it down to the LOCK position.

        • Pull it up to the UNLOCK position again.

      6. Within 30 seconds of the completion of step (4) above, perform the following operation 9 times:


        • turn the ignition switch ON and then the LOCK positions.

        Note

        When the change to self-diagnostic mode is unsuccessful, the system returns to normal mode.

        Tech Tips


        • Self-diagnostic mode is terminated if the ignition switch is turned to the ON position after step (6) above.

        • Do not lock or unlock any doors during self-diagnostic mode.

    2. A0136DGE01

      Check that the system has switched to self-diagnostic mode by checking the blinking frequency of the hazard lamps.

      OK
      The hazard lamps output should be as shown in the illustration.
