Diagnostic Aids
When DTC C1B00:2F is set, the PSCM will transmit an invalid steering angle message over the HS-CAN bus.
When DTC C1B00:62 is set, the PSCM will remove steering assist, and enter into a manual mode and transmit an invalid steering angle message over the HS-CAN bus. The PSCM will also send a message to the IPC to display the POWER STEERING ASSIST FAULT message in the message center.
