Diagnostic Aids
The PSCM will use the motor inside the EPAS gear to calculate the angle and rotation of the steering wheel and then transmit this information to other modules over the HS-CAN bus.
When one or both of these DTCs are 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 send a message to the IPC to display the POWER STEERING ASSIST FAULT message in the message center.
