Decoding U2142: Understanding The Cause Of Your Car’s Communication Failure

The U2142 fault code indicates a loss of serial data communications in the UART system. Devices connected to the serial data circuits monitor for serial data communications during normal vehicle operation. The DTC will set when a supervised periodic message that includes the transmitter device availability has not been received.

A loss of serial data communications Diagnostic Trouble Code (DTC) does not represent a failure of the devices that contain the stored code.
