U0119
Lost Communication with Steering Column Control Module
The Steering Column Control Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Steering-column controls and the steering-lock function can 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.
