Decoding U2139: Understanding Your Car’s Communication Error
The U2139 fault code indicates a loss of serial data communications between devices in the vehicle. The code specifically refers to a lost communication with the Column Integration Module. Devices in the vehicle exchange operating information and commands through serial data circuits.
The devices have pre-recorded information about what messages are needed to be exchanged on the serial data circuits. The U2139 fault code sets when a supervised periodic message that includes the transmitter device availability has not been received. It does not represent a failure of the devices that contain the stored code.
