I see. When the PCM was replaced, did you have the vehicles VIN written to the PCM? Also, if you have SKIM, (Forgive me if I am replying while tired), did the new PCM get the secret key info transferred from the SKIM module?
IIRC one of the final steps is to either manually program the VIN into the PCM or, perform a routine known as "PCM Replaced" in the SKIM module. If you do the "PCM Replaced" function, it will automatically write the VIN to the new PCM and transfer "Secret Key" Data. I really don't have any details on secret key but, all the training I went through recommends transferring it whenever a PCM or SKIM module is replaced.
