U0110

What it means

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.
