U0417Invalid Data Received From Park Brake Control Module
- Generic OBD-II code · Network
- How the car detects it
- U0417 covers implausible data from the park brake control module, the controller of an electric parking brake that clamps the rear calipers by motor and reports apply state and faults on the bus. A receiver stores it when these frames arrive with a bad counter, checksum or an invalid value. No manufacturer explains U0417 in public documents. GM lists it only among history codes of the 2014 Cadillac ELR (PIC5988) that should not lead to replaced or reprogrammed parts unless they can be reproduced. GM's 2025 tables also show that the park brake apply status may be judged under U0418 instead: the front camera module counts it among brake signals whose protection may fail in 3 of 4 messages. U0128 is lost contact, U0317 software. Expect a park brake warning, disabled auto-apply or hill-hold functions and no MIL.
