U0110 Lost Communication with Drive Motor Control Module
The Drive Motor Control Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. On a hybrid or EV the electric drive can shut down or limit power. 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.
