AI DamageU0418 code: Invalid Data Received From Brake System Control Module A
Code U0418 is named in 24 US owner complaints, 2 of them (8%) after a crash. Models: 18, model years 2005–9999.
What the code means
Invalid Data Received From Brake System Control Module A. Generic meaning per SAE J2012 (the same for all makes).
How to read U0418: the letter U means network communication between modules; the second digit 0 marks a generic SAE code shared by all makes; the last three characters 418 identify the specific fault.
ABS/ESC codes: wheel speed sensors, the ABS hydraulic unit and pump, brake booster, pressure and yaw sensors. A hit to a wheel or suspension often damages the wheel speed sensor or its wiring, so on a damaged car this code is a reason to inspect the hub, knuckle and control arms, not just swap the sensor.
