The problem is the new PCM you installed does not have the correct VIN number of your car.
You may be able to relearn the VIN using the preceedure below, however, there is no gaurentee it will work. You may have to have a dealer reset the VIN for you by way of a scan tool.
1) Instert key into ignition and rotate to run position (do not try to start engine)
2) Leave the key in the run position for 10 minutes until security light stops flashing.
3) Turn ignition key to off position for 10 seconds ( no more, no less)
4) Turn ignition to run position again for 10 minutes until security light stops flashing and repeat step 3 and 4 for (1) more cycle.
The process is a security verification step for the VTD system. ( Vehicle Theft Deterent)
Give it a try, let me know.
