U022ELost Communication With Object Detection Maintenance Control Module A
- Generic OBD-II code · Network
- How the car detects it
- U022E reports that object detection maintenance control module A has stopped talking on the vehicle network. The J2012 name points to a unit that keeps the detection sensors of the driver assistance system usable, for example by washing or heating camera, radar or lidar covers; patent US11077472B2 describes such a cleaning device for an object detection sensor. No manufacturer documents U022E publicly, so the real job of module A, its bus and its mounting place come from the maker's wiring data. GM's general logic for the U0100-U02FF range applies: a receiving unit misses the periodic status message at 9-16 V and stores the code. U022F is module B, U052F flags implausible data from A. Expect sensor cleaning or assistance warnings; no MIL is known.
