Unlocking The Mystery Of U1239: A Guide To Diagnosis
The U1239 fault code is related to the class 2 serial data circuit in automobiles. Modules in the circuit monitor for serial data communications during normal vehicle operation.
When a module does not associate an identification number with at least one critical parameter within 5 seconds of beginning serial data communication, the U1239 Diagnostic Trouble Code (DTC) is set.
The U1239 code specifically indicates invalid or missing data for experimental #4.
