U0141Lost Communication With Body Control Module A
- Generic OBD-II code · Network
- Turns on the check-engine light
- How the car detects it
- U0141 names the first of several body controllers. Unlike U0140, which stands for the single main BCM, the letter suits cars that spread body tasks over more units, and each maker decides which one is A. Mitsubishi uses U0141 for an ETACS timeout: its body controller ETACS-ECU stops sending, and keyless entry, liftgate, airbag, brake and steering units log the loss; bulletin TSB-19-42B-003 revised the procedure for Outlander, Lancer and Outlander Sport up to 2019. FCA labels the module IPM (BCM) or, in older airbag lists, the front control or totally integrated power module; on the 2021 Chrysler 300 a PCM flash cures a MIL that comes with it. On the 2023-24 Audi e-tron the gateway stores U014100 when the ignition will not switch on, cured by a software update of the comfort control unit J393.
