Lost Communication with Door Driver Module
The Door Driver Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. The driver-door module is silent; its window, lock, and mirror controls fail. 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.
