The incomparable issue could have damaged the controller if wiring is different between the two. At minimum there will be trouble codes that may have put the system into a safe locked mode. ( out of operation )

First step is to use a scan tool to check for codes then clear any it has. If the system does not respond, you will need a wiring diagram / factory diagnostic tree to figure out where the problem is.
