U0428 Mercury Code - Invalid Data Received From Steering Angle Sensor Module
Quick Answer
The Steering Angle Sensor Module (SASM) broadcasts the absolute steering angle value to the Power Steering Control Module (PSCM) over the HS-CAN at predefined intervals during every drive cycle from the first ignition ON status. Common causes include Faulty Steering Angle Sensor Module (SASM), Steering Angle Sensor Module harness is open or shorted, Steering Angle Sensor Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
