U023ALost Communication With Image Processing Module A
- Generic OBD-II code · Network
- How the car detects it
- U023A reports loss of image processing module A, usually the windscreen camera feeding lane keeping, auto high beam and collision warning. Ford calls it IPMA: Mustang 2024 (SSM 52077) logs U023A in the SCCM after a remote start with Pre-Collision Assist unavailable, and F-150 2021-2023 (TSB 24-2267) shows U023A:08 after SCCM programming, fixed by IPMA software. GM PIT5482 (2016 Tahoe, Escalade, Silverado and others) forbids replacing the front camera for a history U023A with Service Front Camera; PIC5814 (2013 ATS, XTS, SRX) says the short range radars log it at every shutdown, no repair needed. Toyota T-TT-0352-15: Highlander meters swapped from cars without LDA keep it for good. Ford's 2014 list: no MIL.
