U0530 Invalid Data Received From Object Detection Maintenance Control Module B

Module B of this family is a second maintenance controller for object detection sensors, for instance one serving another sensor group or the other side of the vehicle. The generic definition offers no public explanation, and no manufacturer document names U0530. Denso's patent US11451765 illustrates the kind of decision such a unit supports: two sensors sharing a field of view are compared, and when they disagree about the objects they see, one of them is judged dirty and marked for cleaning. U0530 is stored when a receiving module gets frames from module B that fail checks such as range, counter or checksum. The outcome is usually a message that a sensor or assistance feature is unavailable, not any effect on drivability. Total loss of B is U022F; the A unit is U052F.

Likely causes

Software level of module B not matching the receiving controller
Module B internal fault, e.g. after water or road salt exposure
Intermittent contact in the data line or connector to module B

Symptoms

  • Message that a sensor or assistance function is unavailable
  • Automatic sensor cleaning on one side or sensor group not working
