Hey Guys,

I have a 2007 (new model) Sierra 1500 that recently has the "service the airbag" notice show up on the dash. I am guessing there is a sensor in the bumper? Anybody done one before? Is there a link to the service manual for replacing one anywhere?

Thanks in advance,
Brian

 

Your going to have to hook up a scanner to aee what exactly went wrong. Alot can go wrong with airbags.

 

You've got resistance measurements at each bag ignitor (2-5), internal checks on the airbag controllers, resistance checks on the 9 sensors in the system, communications checks between airbag and BCM/PCM/ABS...yeah, you need a Tech II.

The most common fault is a defective ignitor pack. If you are not a professional mechanic, I would HIGHLY HIGHLY HIGHLY discourage self servicing your modern air bag system. A minor mistake like having a static burst go from your hand to the ignitor on a bag can end very badly, regardless of how rare it may be. Each airbag is roughly 225 grams of explosives (a little less than half a pound)- an accidental triggering can sever limbs from a person.

 

Thanks for the info guys, I meant to state that I was planning on getting it scanned. I don't own one, is this the type of scan Autozone can do?

 

No, this is a dealership or other qualified repair center job. A Tech II or equivalent is required, Autozone doesn't equip it's stores with high end multidiagnostic scanners (their most expensive scanner might be able to pull codes from your antilock brake system, can't touch BCM or SRS)

 

Thanks Buddy! I'll have to take it in.

 

My AutoCal read the code on my 03 Silverado. Googled the code and it was a problem with the front right sensor. Replaced that and all is well.
