Lost Communication with Rear Seat Entertainment Control Module
The Rear Seat Entertainment Control Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Rear-seat entertainment stops working. Typical causes are loss of power or ground at the module, an open or shorted CAN/LIN bus wire, a connector fault, or an internal module failure.
