It must be programed using special equipment like a Tech II, used by dealers.
You don't, the dealer or repair shop does.
i have an 02 impala and i recently found out my bcm is bad. I found out that this is located on the left hand side of the steering column.... it should be the same in the 01 since the parts can be swapped in both cars. i hope this helps

what does a bcm in a 2000 cavalier control
Because its a chevy!! Agreed. Bad ground from body control module (bcm) kills the relay switch. Around $400 at the dealer 4 years ago.
Where is BCM located on 2001Grand Prix
The best thing to do is to buy a BCM from the GM dealer and he will programme it for your specific vehicle, in your case a 2001 cavalier. I have the exact car, same year and I also need a new BCM. I'm picking one up at my local GM dealership for about $240Can. that includes the BCM and the programming. Hope this helped, and good luck.
