- Generic OBD-II code · Network
- How the car detects it
- U0232 means side obstacle detection control module A, one of the rear corner radars for blind spot and cross traffic warning, is missing from the network. Saab's 2011 list puts A on the left; Toyota bulletin T-SB-0063-19 (Tacoma 2016-2018) calls U0232 loss of the blind spot slave module. Volvo journal TJ 30858 (XC90, S90, 2016-2018) has the right unit log U023292 for its partner and prescribes new software. Ford TSB 24-2180 (Expedition, Navigator 2022-2024) finds U0232 in the IPMA when mud, snow or ice packs behind the bumper and adds shields. A Chrysler STAR case (Durango 2020) traced it to an open fuse 95 and a pinched circuit in the liftgate. Blind spot alerts go dark; no MIL.
