NAVIGATION: NAVIGATION SYSTEM: B1595, B15D5: No Response from Rear Seat Entertainment System
B15D5 - Rear Seat Entertainment System Disconnected

DESCRIPTION

The stereo component tuner assembly and television display assembly are connected by the AVC-LAN communication line.

The multi-media interface ECU is also connected to the stereo component tuner assembly by the AVC-LAN communication line.

The navigation receiver assembly is also connected to the multi-media interface ECU by the AVC-LAN communication line.

When an AVC-LAN communication error occurs between the stereo component tuner assembly and television display assembly, these DTCs will be stored.

HINT
* If either B1595 or B15D5 and either B1561 or B159F are output, troubleshoot for B1561 or B159F first.
* If either B1561 or B159F and either B156B or B156E are output together with either B1595 or B15D5, troubleshoot B156B or B156E first.

HINT
* *1: 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.
