NAVIGATION SYSTEM (for DVD), Diagnostic DTC:B1569

DTC Code DTC Name
B1569 DVD-ROM Deck Disconnected

DESCRIPTION

The display and navigation module display and navigation module board are connected by the IEEE cable.

When an IEEE communication error occurs between the display and navigation module display and navigation module board, this DTC will be stored.

DTC No. DTC Detection Condition Trouble Area
B1569

When either of the conditions below is met:


  • Navigation module board is/was not connected while the power switch on (IG or ACC).

  • Communication between the master unit and the navigation module board is not possible when the engine is started.

  • Navigation module board power source circuit

  • IEEE cable

  • Display and navigation module display

  • Navigation module board

Tech Tips


  • Even if no fault is present, this DTC may be stored depending on the battery condition or hybrid system start voltage.

  • The display and navigation module display is the master unit.

INSPECTION PROCEDURE

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 IEEE communication.

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