U0418 on 2022-2024 Ford Maverick — Invalid Data Received From Brake System Control Module 'A'
1 vehicles · 1 makes
Most Reported On
U0418 is an OBD-II diagnostic trouble code meaning “Invalid Data Received From Brake System Control Module 'A'.” This network code means a control module received data from the Brake System Control Module (typically the ABS/electronic stability module) that failed its validity or plausibility checks. The modules in your car constantly exchange information over a communication bus, and the receiving module decided the brake module's messages were corrupt, out of range, or implausible. Because it touches the ABS and stability control system, this can disable those safety features, so it should be diagnosed promptly. This code is most commonly reported on 2022-2024 Ford Maverick.
