U052FInvalid Data Received From Object Detection Maintenance Control Module A
- Generic OBD-II code · Network
- How the car detects it
- Object detection maintenance control modules appear in the generic code list, but no manufacturer has published what they do or when this fault sets. The name points to a unit that keeps cameras, radar or lidar used for object detection usable, for example by running washers, air jets or heaters. Ford's patent US10569746 describes such logic for a roof-mounted lidar: a contactless cleaner runs first, and a wiping cleaner follows only if the window is still too opaque. U052F means a receiver, most likely the driver-assist controller, gets messages from maintenance module A that are corrupt or implausible, so it cannot rely on the reported cleaning or blockage status. Assistance features may report a blocked sensor or switch off. Loss of the module is U022E; module B is U0530.
