U022ELost Communication With Object Detection Maintenance Control Module A

U022E is a network communication fault indicating that a control module responsible for object detection maintenance (such as a camera or radar cleaning system) has stopped reporting on the vehicle's Controller Area Network (CAN) bus. The computer has detected that it is no longer receiving the periodic status messages it expects from this specific module, which can disable driver-assist features that rely on a clear sensor view.
