Diagnostic Aids

When DTC U0300:00 is set, the PSCM will disable steering assist, and enter into a manual mode and transmit an invalid steering angle message over the HS-CAN bus. The PSCM sends a message to the instrument panel cluster (IPC) to display POWER STEERING ASSIST FAULT in the message center.
