Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Normal Operation
The PSCM receives vehicle configuration information from the IPC and stores the information for later use. When the ignition is set to ON, the PSCM compares the ECU configuration stored in memory to the configuration message sent from the IPC. If the stored data does not match the received data, a DTC is set. This is most likely due to a new module not being programmed correctly or the programming was interrupted.
