The Airbag Control Module (ACM), sometimes referred to as the Airbag Electronic Control Unit (ECU) or the Supplemental Restraint System (SRS) module, is the central computer responsible for monitoring, managing, and deploying the vehicle's airbags and sometimes the seatbelt pre-tensioners in the event of a collision. It functions by processing data from various crash sensors located throughout the vehicle. If the ACM determines that the crash dynamics meet the criteria for airbag deployment, it will activate the appropriate airbags.

In addition to deployment criteria, the ACM often logs crash data, sometimes called "black box" data, which can provide valuable information about the events leading up to and during a crash.
The location of the ACM can vary depending on the make, model, and year of the vehicle. Common locations include:
-
Under the center console: This is a frequent location in many vehicles. Removing the center console might reveal the ACM beneath it.
-
Under the dashboard: Sometimes it's located on the driver's side, sometimes on the passenger's side, either near the center or more towards the sides.
-
Inside the kick panel: The kick panels are the areas beneath the dashboard where the driver's or passenger's feet rest. The ACM can sometimes be found behind these panels.
-
Under the front seats: Some vehicles have the ACM located beneath one of the front seats, often secured to the floor or the seat frame.
If you provide the specific make, model, and year of a vehicle, I can attempt to give a more precise location. Otherwise, the best way to determine its location would be to refer to the vehicle's service manual or consult with a professional mechanic or technician familiar with that particular vehicle.
