U0418 on Ford
Invalid Data Received From Brake System Control Module 'A'
U0418 on Ford vehicles indicates invalid data received from brake system control module 'a'. Au7o has documented this code across 1 Ford model — most commonly on Maverick. 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.
Common Causes of U0418
- •Low or unstable battery/system voltage (common on stop-start vehicles)
- •Faulty ABS / brake control module or its software needing an update
- •Corroded or loose connector at the brake module harness
- •Damaged CAN bus wiring (chafed, pinched, or shorted high/low pair)
- •Poor or high-resistance ground at the module
- •Water intrusion or corrosion in connectors
- •Module reprogramming or configuration error

Ford Maverick(1 issue)
- HPCM Software Forces Vehicle into Neutral While Driving (Recall 24S33 / 24V-330)2022-2024
On affected 2022-2024 Maverick Hybrid trucks, a recent update to the Hybrid Powertrain Control Module (HPCM) software calibration may result in a forced neutral condition while driving, causing the vehicle to coast to a stop and automatically shift to Park, along with a wrench light, multiple warning messages, and an audible chime. After shifting back into Drive the vehicle enters a limp home mode with limited torque at speeds up to 30 mph. Ford's powertrain controls team determined that new Hybrid Transmission Internal Park Module (HTIPM) software released for use in service in January 2024 can result in DTCs U1010 and U1011 shortly after installation, and Ford was aware of 315 warranty claims in North America as of April 15, 2024. The recall covers approximately 8,727 vehicles (Maverick population ~8,369).
