U0514Invalid Data Received From Mirror Control Module A
- Generic OBD-II code · Network
- How the car detects it
- J2012 provides two mirror control units, and U0514 concerns unit A: its frames keep arriving, but the receiver finds the content unusable, for instance a signal flagged invalid, a wrong counter or checksum, or a value outside the defined range. FCA ties the letter to the cabin mirror. In its Grand Cherokee case S2108000013 the partner code U0213 is called interior mirror control module A and was logged in the BCM after a configuration restore had wrongly declared a combined rear view mirror module fitted. Jaguar Land Rover shows the invalid-data side with its own code B1974-86 on the 2020 Evoque, caused by mirror software and without any effect on function. Depending on the unit, auto-dimming, a camera mirror view or memory settings may be unavailable. U0213 means silence; module B uses U044F.
