U0317Software Incompatibility With Park Brake Control Module

  • Generic OBD-II code · Network
How the car detects it
U0317 tells that the park brake control module of an electric parking brake runs software or a calibration another module does not accept. Following GM's generic U03xx logic it is checked at 9-16 V with normal bus traffic, sets when a module is not configured properly and needs no wiring test; the cure is setup or programming. No manufacturer documents this J2012 meaning publicly. Mitsubishi reassigns the number: for the 2017 Outlander (TSB-17-23-001) U0317 stands for a CAN time-out with the EPB ECU, which a wrongly programmed TCM stored as P0317 instead; a TCM reflash corrects it. On such vehicles read U0317 as a communication fault. U0128 means lost contact, U0417 invalid data. Park brake warnings or disabled auto functions are possible; no MIL.
