Hello,

This body processor module (this is what Jaguar calls the BCM) needs to the synchronized with the vehicle.
Without synchronizing (programming) this will not be recognized by the vehicle and it will not function.
In order to do the synchronizing you will need a Jaguar PDU (portable diagnostic unit).

Please let me know of any questions.
Thank you.
