My Snap On MT2500 does airbag stuff up to 2009, but what I noticed is anything newer than 02 I can't communicate with. I can scan and clear codes on vehicles older than 02, on my 04' Colorado it is linked with the serial 2 data wire BUT I still can't communicate with it. For what it's worth my dealer charged me $85.00 to scan the airbag, and put the light out. Mine came on because I removed the drivers side seat not thinking about the connector on the bottom of the seat.
