DESCRIPTION

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

When a MOST communication error occurs between the display and navigation module display and the multi-display controller sub-assembly, these DTCs are stored.





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

INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

1. 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 MOST communication.
* This DTC may be stored when a MOST communication error occurs due to electrical noise.

B -- CHECK FOR DTC
A -- Continue to next step.

2. REMOVE OPTIONAL COMPONENTS (INCLUDING ASSOCIATED WIRING)

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

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

NEXT -- Continue to next step.

3. CHECK FOR DTC

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

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

OK:

No DTCs are output.
