DESCRIPTION

The display and navigation module display and multi-display assembly are connected by the AVC-LAN communication line.

When an AVC-LAN communication error occurs between the display and navigation module display and multi-display assembly, these DTCs will be stored.

HINT
* *1: 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.

* This DTC may be stored when an AVC-LAN communication error occurs due to electrical noise.
B -- CHECK DTC
A -- Continue to next step.

2. 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.

NEXT -- Continue to next step.

3. CHECK DTC

(a) Clear the DTCs Navigation System (for HDD).

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

OK:

No DTCs are output.

NG -- CHECK HARNESS AND CONNECTOR (MULTI DISPLAY ASSEMBLY POWER SOURCE)

OK -- END

4. CHECK HARNESS AND CONNECTOR (MULTI DISPLAY ASSEMBLY POWER SOURCE)

(a) Disconnect the M9 multi display assembly connector.

(b) Measure the resistance according to the value(s) in the table below.
