Ok, my wifes alero died today so I checked it out n the bcm was bad, I swapped it out and did the relearn. Started right up, but now the airbag light is on and the radio is locked. Obd 2 says no codes, I may have to have the radio flashed but I never removed it ne ideas?

Sounds like a trip to the dealer and their tech II is in order, the bcm vin is not correct.

Try this procedure before you pay the stealership.

Can only guess at the air bag. Maybe a bad connection or a problem with the new BCM.

Is the replacement BCM from a same-year Alero? Might be a databus compatibilty issue.
