U052F Invalid Data Received From Object Detection Maintenance Control Module A

Check engine lightUsually off

Limp modeNo

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.

Likely causes

Software or configuration mismatch of maintenance module A
Internal fault of the maintenance module (e.g. moisture ingress)
Wiring or connector fault on the module's data line

Symptoms

  • Sensor blocked or sensor cleaning message
  • Driver assistance features temporarily unavailable
  • Sensor washing or heating not working
