Where is the assist airbag module located?
In most vehicles there isn't a universal component called an "assist airbag module." The relevant hardware for deployment is the airbag control module (ACM) and the individual airbag units. The ACM is usually tucked away behind the glove box or under the center console, while the driver airbag sits inside the steering wheel and the passenger airbag inside the dashboard. Exact locations vary by make, model, and year.
Below is a guide to the typical placements you may encounter across many modern cars. This information is intended for understanding what parts are where; do not attempt to access or modify airbag components yourself. If you have a concern about a deployed or faulting airbag, seek a qualified technician or your dealer.
Common locations for the airbag control module (ACM)
ACM locations are chosen to protect sensitive electronics and to minimize impact risk. The following placements are among the most common across different brands.
- Behind the glove box on the passenger side (a frequent location in many mid- to late- model vehicles).
- Under the center console or along the transmission tunnel in some sedans and SUVs.
- Behind the lower dash near the passenger footwell or kick panel in select models.
These locations are representative but not universal; some vehicles place the ACM in less obvious spots or within the dash assembly itself. Always verify with the service manual for your specific vehicle.
Where the airbag modules themselves are housed
The physical airbag modules—the driver and front passenger airbags—are integrated into the structures you interact with daily. Knee or side airbags expand in different regions depending on the design.
- Driver airbag module: built into the center of the steering wheel, behind the horn pad.
- Front passenger airbag module: mounted in the upper portion of the dashboard on the passenger side.
- Knee and side airbags: located lower in the dash, under the steering column, in the lower dash panels, seat backs, or door panels depending on the model.
Again, exact placement varies by model and trim. For precise locations, consult the owner's manual or service documentation for your vehicle.
Summary
Airbag system layouts vary widely by vehicle. The common pattern is an airbag control module placed behind the glove box or under the center console, driver airbags in the steering wheel, and passenger airbags in the dashboard. Always refer to the specific documentation for your car and avoid attempting any disassembly of airbag components yourself.
