Where is 2006 Ford Focus airbag module?

The airbag module (also called the Airbag Control Module or ACM) in a 2006 Ford Focus is located under the dashboard, on the passenger side. It's usually near the passenger's feet, but its precise location can vary slightly depending on trim level and options. You'll likely need to remove some trim panels to access it.

Important Note: Working with the airbag system is extremely dangerous. If you're not a trained professional, you should absolutely not attempt to access or repair the airbag module yourself. Disconnecting the battery does *not* fully discharge the system, and accidental deployment can cause serious injury or death. If you need work done on the airbag system, take your vehicle to a qualified mechanic or dealership.
