I keep getting a service air bag message. How much does a dealer charge to "service an airbag"

Also, what do they do when it is serviced? reset the sensor to flash message after 10,000 miles perhaps

David, I think you're more likely to get an answer for this if you post it in the forum specific to your model Cadillac. The Northstar forum is more related to engine/drivetrain issues than airbags. Electrical info forums might help, too. Hope you get an answer.

Good luck...
