Not unless you can get someone from a dealer to make a house call with a WDS, NGS+ or equivalent.
The PATS Module and PCM share security data when first installed together, making them a matched pair. After the security data sharing, these modules will not function in other vehicles unless reprogrammed. There is a special procedure that must be carried out using the dealer tool if either the PATS Module or PCM is replaced.
