DESCRIPTION

The television display assembly and multi-display controller sub-assembly are connected by an AVC-LAN communication line.

The display and navigation module display is connected to the multi-display controller sub-assembly by a MOST communication line.

This DTC will be stored when an AVC-LAN communication error occurs between the multi-display controller sub-assembly and television display assembly.





HINT
* Even if no fault is present, this DTC may be stored depending on the battery condition or engine start voltage.
* The display and navigation module display is the master unit.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

(b) Recheck for DTCs and check if the same trouble occurs again.

Result:





B -- END
A -- Continue to next step.

2. CHECK OPTIONAL COMPONENTS (INCLUDING ASSOCIATED WIRING)

(a) Check for optional components.

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

Result:





HINT
* 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.
B -- CHECK DTC
A -- Continue to next step.

3. REMOVE OPTIONAL COMPONENTS (INCLUDING ASSOCIATED WIRING)

(a) Remove optional components (including associated wiring).

NOTICE:
Do not remove optional components or associated wiring without the permission of the customer.
