NAVIGATION / MULTI INFO DISPLAY: NAVIGATION SYSTEM (w/ USB Audio System): B1595,B15D5: No Response from Rear Seat Entertainment System
B15D5 - Rear Seat Entertainment System Disconnected

DESCRIPTION

The television display assembly is connected by the AVC-LAN communication line.

The navigation receiver assembly is also connected to the television display assembly by the AVC-LAN communication line.

These DTCs will be stored when an AVC-LAN communication error occurs between the stereo component tuner 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 navigation receiver assembly is the master unit.

INSPECTION PROCEDURE

NOTICE:
* After replacing the stereo component tuner assembly of vehicles subscribed to pay-type satellite radio broadcasts, registration of the XM radio ID is necessary.
* 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 AVC-LAN communication.
* This DTC may be stored when an AVC-LAN communication error occurs due to electrical noise.
