Looking for the Airbag Module on 09 Tahoe

Front impact sensor? I replaced one on my car, recently.

Jon, I’m confused. You swapped the front impact sensors (accelerometer sensing modules)?
“I have a B0083 code and swapped the sensors underneath.”

Now you are looking for the Airbag Sensing and Diagnostic Module Replacement?
My information shows it located under the driver’s seat.

The service information says to remove the seat and reposition the carpet to access it. You’ll see the electrical connectors. When replacing, the arrow on the module must point forward.

If you’re installing a new replacement part it needs to be programmed.

Addition: **Inflatable Restraint Side Impact Sensor Module**s are located, one each, behind the door trim panels (and water deflectors under the trim panels). 2 screws hold them into keyhole slots. Take the screws out and slide them to remove.

All standard cautionary and safety practices must be observed when working on the SIR air bag system.

I’m not sure what you’re looking for at this point.
