Unlocking The Mystery Of U1233: A Guide To Diagnosis
The U1233 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 critical operating parameter is not received, the module uses a default value for that parameter.
If a module does not associate an identification number with at least one critical parameter within 5 seconds of beginning serial data communication, the U1233 DTC is set.
This fault code specifically indicates invalid or missing data for navigation.
FAQ
