Help me, I need to locate airbag items.

Tonight I'm teaching an AIR bag training for the firefighters and I pulled my Tahoe in the bay to go over the equipment and what it looks like. I need to locate:
 

• Front sensors
  
• Brain Box.
  
• Location of side door sensors

 
Already have a photo of the head curtain air cylinder from when I pulled the remote control wire out for more range. Any other info or photo's of the Tahoe system would help. I know it has sensors in the tunnel that trigger side curtain in the event of a rollover. Thanks in advance for helping to train our firefighters.

The Front End Sensor is located underneather the radiator support brace.

The Brain box called the Sensing and Diagnostic Module is located underneath the drivers seat.

The side impact sensor is located just slightly to the aft of dead center in the front doors underneath the door trim panel and the water deflector.

I was hoping you would reply...

2 boxes under the seat, is the airbag brain the one labeled BOSCH?

Do the doors have any sensors in them?
 
Does the side curtain use 1 gas inflator or 2? I know there is one in the rear, I am guessing there is another in the front A-Post?

Is the vehicle equipped with seat belt pretensioners?

Are the front sensors the ones clipped on the radiator brace. Small and black? One has a yellow wire the other blue?

Correct the box labeled Bosch is your baby.


The front doors each have a sensor in them if your Tahoe is equipped with the roof and side rail inflatable restraints (see my paragraph 3 above).


And yes there are two SIR inflator modules on each side for a total of 4 (forward and rear) that activate the side rail bags.


The front seat belts are equipped with pretensioners that are operated by a small explosive charge called a Cad.

You have described precisely the front sensors.

Thank you so much. Sorry about the door question, I thought I read in the door sill.
 
By chance you don't have a diagram or picture of the Rollover sensor located in the tunnel do you?

I can't thank you enough. This training will actually get forwarded on to some other fire departments.
 
Thanks for helping!

Great!
Glad I could help out one of the most respected professions on the planet IMHO.

+1000!!!!!!!  he is a great asset to have here.

Ditto here and second his comment about firefighters.

o.k., well since you did so much for the firefighters ZX, I think it's only right that I come back and tell you how it went. We went through every component of new airbag and safety device technology and things to look out for. It was about a 2 1/2 hour powerpoint presentation that included online video's and animations. When it was all said and done we had a hybrid for the guys to check out and go over. After that we went over to my Tahoe which had every piece of safety equipment labeled. They commented quite a bit about the new guys who cut the D post without stripping plastic and in this case the side curtain cylinder was directly in the cut zone. We also demonstrated the smart airbags that turn off and on depending on weight. There also was a great deal of discussion about how the side curtain airbag could deploy when we are in the process of removing a door, especially if a cell phone or laptop is backfeeding power into the vehicle through the cigarette lighter. It went 40 minutes longer than scheduled but not because I held them, they stayed walking around discussing everything. Comments I received today were great. You rarely hear these guys compliment any training since they can become boring and mundane but they thought it was great. Many, many compliments.

The training has been requested on CD by some of our part time people who are full time on other departments. These trainings seem to travel around us pretty fast if people like them.

Thanks again and thanks everyone for the great comments about firefighters. We love our jobs and most of the people we protect (except the ones that come at me with baseball bats).
