U1254: The Low Speed Can Communication Bus
The U1254 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 U1254 Diagnostic Trouble Code (DTC) is set.
This code indicates that there is invalid or missing data for network control.
