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:

[ul][*]Front sensors[*]Brain Box.[*]Location of side door sensors[/ul]

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 thedoors have anysensors 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.
