U0428 — Invalid Data Received from Steering Angle Control Module

About U0428

U0428 is a generic (obd-ii standard) network communication diagnostic trouble code. It belongs to the U-prefix family of codes, which covers inter-module network communication (CAN, LIN, FlexRay, or similar) faults.

Scanning & clearing: Network (U) codes report communication faults between modules. When diagnosing U-codes, checking the vehicle's CAN bus integrity, supply/ground at each module, and reading all modules for related faults is usually the first step.

Because U0428 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The receiving control module, commonly the ABS and stability control module, the PCM, or the BCM, monitors the steering angle data sent over the CAN network by the Steering Angle Control Module or steering angle sensor. DTC U0428 sets when the receiving module finds that the steering angle data is present but invalid, implausible, or outside the expected range for the current driving conditions. This is a data integrity or plausibility problem rather than a complete loss of communication, so messages are arriving but cannot be trusted for stability control and other steering related calculatio...
