I have a 2005 silverado 2500hd 4x4 that is giving me the "service airbag system" message. I have checked the fuse (it's fine) and I don't get any codes when I use a scan tool from NAPA. Any suggestions? Thanks in advance.

 

you may have a broken wire under the drivers seat, under the carpet, that was my problem, worth checking out. good luck!

 

You need to go somewhere where they can scan the Air Bag computer. Most parts stores can only scan the PCM. Too many parts to GUESS without codes. I have a fleet account that uses Silverados and Express vans, I have replaced many crash sensors. The Express only has 1 in the front but Silverado has one on the left and one on the right. You need the codes
