DTC U0428: Invalid Data Received from the Steering Angle Sensor Module: Description

WARNING: This page is about a different car, the 2015 Ford Special Service Police Sedan and 2015 Ford Police Interceptor Sedan. However, it is still accessible from the selected car via links, so may be relevant.

The PSCM monitors the HS-CAN when the ignition has been on for more than 5 seconds, the voltage to the PSCM is greater than 9 volts and there are no DTCs present inhibiting PSCM operation. The SASM is attached to the SCCM and sends steering angle information directly to the SCCM. The SCCM then sends the information as messages to the PSCM over the HS-CAN.

DTC U0428:00 (Invalid Data Received from Steering Angle Sensor Module: No Sub Type Information) - This DTC sets if the PSCM receives an invalid or unknown message from the SCCM instead of the actual steering angle data.
