DTC U045A: Invalid Data Received From Parking Assist Control Module A: Description

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 10 volts and there are no DTCs present inhibiting PSCM operation.

The PAM 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 PAM sends out "invalid", "fault" or "unknown" instead of the actual sensor data. For a list of the messages sent to the PSCM from the PAM, refer to the Network Message List in Description and Operation in the Power Steering article.
