DTC U0429: Invalid Data Received from the Steering Column Control Module: Description

The PSCM monitors the HS-CAN messages 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 that are inhibiting PSCM operation.

The SCCM uses input from several sensors and components to gather vehicle data, then sends this data to the PSCM. If the data is corrupted or invalid, the SCCM sends out "invalid", "fault" or "unknown" instead of the actual sensor data. For a list of the messages sent to the PSCM from the SCCM, refer to the Network Message List in Description and Operation in the Power Steering article.

• DTC U0429:00 (Invalid Data Received from Steering Column Control 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.
