U0112: Lost Communication With Vehicle Dynamics Control Module

The U0112 code is a Controller Area Network (CAN) fault code. CAN is a vehicle bus standard designed to interconnect automotive devices without a host computer. The U0112 code sets when a periodic message from the Battery Energy Control Module ‘B’ has not been received.

CAN bus uses two dedicated wires for communication, CAN high and CAN low.

The Diagnostic Trouble Code (DTC) sets when there is a lost communication with Battery Energy Control Module ‘B’. The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise.
