U0512Invalid Data Received From Seat Control Module D
- Generic OBD-II code · Network
- How the car detects it
- U0512 has a documented GM case that goes beyond comfort functions. On the 2020 Cadillac CT5 with option UGN, the image processing module, which handles camera data for driver assistance, could set U0512 and display Service Driver Assist. GM named software as the cause, told technicians to clear the code and recheck, and to follow normal diagnosis only if it returned at once (PIC6408, revised as PIC6408A in October 2020). The bulletin does not say which seat information the camera module uses. In other cars, module D is simply a fourth seat unit; Ford's matching of letters to generic slots is shown by U024B/U024C for its seat modules G and H. Lost contact with module D gives U0211.
