DTC U053B: Invalid Data Received from Image Processing Module A: Action
WARNING: This page is about a different car, the 2018 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
CARRY OUT a self-test of the IPM-A. If the diagnostic scan tool indicates the module is not responding, REFER to COMMUNICATIONS NETWORK to diagnose the network communication concern. If IPM-A DTCs are present, REFER to REAR VIEW MIRRORS to diagnose the IPM-A system fault. If there are no DTCs in the IPM-A, SET the ignition to OFF. DISCONNECT and INSPECT all IPM-A electrical connectors and related in-line connectors for corrosion, bent pins, pushed-out pins and spread terminals. REPAIR as necessary.
