U0541Invalid Data Received From Entrapment Control Module B
- Generic OBD-II code · Network
- How the car detects it
- Entrapment control module B is the second slot for a separate pinch-protection unit. Some designs detect a person before contact: a capacitive strip changes its electric field as a hand approaches, and the attached electronics pass the result to the closure controller either as a switched output or as LIN or SAE J2602 data, as a review of tailgate anti-pinch approaches explains; patent US20030151382 likewise combines a capacitive field with a position sensor. U0541 is stored when frames from such a unit B are malformed or implausible. No manufacturer publishes the code. FCA's case S2208000106 shows how confusing two-sided sensing can be: its left and right liftgate pinch sensor codes may point to the wrong side, so check both connectors. U0240 covers complete loss of module B.
