PROCEDURE


  1. CHECK OPTIONAL COMPONENTS (INCLUDING ASSOCIATED WIRING)


    1. Check for optional components.


      1. Check that optional components (including associated wiring) which generate radio waves are not installed.

        Result
        Result Proceed to
        Optional components (including associated wiring) are installed. A
        Optional components (including associated wiring) are not installed. B

        Tech Tips


        • Electrical noise from radio waves generated by optional components or the wiring for those components may affect AVC-LAN communication.

        • This DTC may be stored when an AVC-LAN communication error occurs due to electrical noise.
