U053AInvalid Data Received From Entrapment Control Module A
- Generic OBD-II code · Network
- How the car detects it
- Entrapment control modules handle pinch protection for powered closures where it is not built into the drive, typically sliding doors, liftgates or roofs with sensing edges. For windows, roof panels and partitions FMVSS 118 sets the goal: stop and reverse before 100 N act on the test rod. Chinese patent CN102923068B shows a dedicated anti-pinch module for a back door that drives the motor, reads a Hall sensor and exchanges commands and diagnostic messages with the body controller over CAN. U053A means such a module A is transmitting, but its data are rejected. No manufacturer documents the code or what module A protects. Expect the affected closure to refuse automatic closing or to reverse unexpectedly; U0239 is the lost-communication counterpart.
- What you may notice
- Power closure will not close automatically
- Closure reverses without an obstacle
- Likely causes

- RareBus wiring to the module damaged, e.g. in a liftgate or door hinge
