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.

1. CE1: CHECK THE IPC CONFIGURATION 
   • Review the vehicle repair history for recent service actions related to the IPC.
   • Have there been any recent service actions with the IPC? 

     Yes	No
     REPEAT the PMI procedure as directed by the diagnostic scan tool.	REFER to the Instrumentation, Message Center and Warning Chimes article and DIAGNOSE any IPC concerns.
