U120C: Understanding The Mysterious Lost Communication With Steering Angle Sensor
The u120c fault code is a Diagnostic Trouble Code (DTC). It sets when the Powertrain Control Module (PCM) doesn’t receive a brake booster vacuum signal from the Anti-lock Brake System (ABS) Module. This happens over the Controller Area Network (CAN) C bus.
The code is specifically known as the Lost Brake Booster Signal.
FAQ
