Good Morning All

I have just purchased 2 Heated Seat Control Modules P/N 13502042.
I have already changed the heated seat pads on both seats and enormous costs, and still not working, based on this I presume its the Heated Seat Control Modules.
When they arrive and I re-fit the new modules, do I have to get them coded in ?

Thanks
