U0553Invalid Data Received From Lighting Control Module — Rear B
- Generic OBD-II code · Network
- How the car detects it
- Rear lighting control module B is a second controller for the rear lamps. U0553 is set when its messages are received but their content is implausible. No manufacturer documents U0553 publicly, yet the partner code U0252 hints at what the module often is: GM's list for the Saab 9-5 calls U0252 the trailer interface control module, and Ford links U0252 and U0137 on 2021–2024 F-150, Expedition, Navigator and the 2024 Ranger to a trailer module that dropped off the CAN bus, fixed by disconnecting and reprogramming it. On 2023–2025 Super Duty trucks, a badly tightened ground G201 set U0252 among other codes. U0484 is the same fault for rear module A. Trailer or rear lamp functions may fail; no MIL.
