U0534Invalid Data Received From Side Obstacle Detection Control Module B
- Generic OBD-II code · Network
- How the car detects it
- Module B is the right-hand rear corner radar in GM and Ford numbering: Saab's 2011 list calls U0233 the right side-object module, and Ford's Expedition/Navigator bulletin 24-2180 pairs U0233 with the right sensor. Toyota uses U0233 for the master sensor of the Tacoma blind spot system, where bulletin T-SB-0063-19 had both sensors replaced and re-aimed with a reflector tool. No manufacturer document cites U0534, so its setting criteria are not public. The code stands for traffic from the right unit that arrives normally but whose payload the receiving module rejects. Typical outcome: the right blind spot indicator stays dark, cross traffic alert is unavailable and a service message appears. A wet or damaged plug at the bumper is a frequent trigger. U0233 means the module is silent; the left unit is U0533.
