Where is my airbag module located?

The airbag control module (ACM) is usually tucked away inside the vehicle, not in a clearly visible spot. The actual airbags themselves sit in the steering wheel (driver) and in the dash area for the passenger, while the ACM is typically hidden near the passenger side dashboard, under the center console, or in the kick panel depending on the make and model. For your exact location, check the owner's manual or ask your dealer or a qualified technician.

Understanding the airbag system

Airbag systems consist of two main parts: the airbags (the physical bags that deploy) and the airbag control module (ACM) that detects a crash and triggers deployment. Some vehicles also use an occupant classification module (OCM) to help decide whether to deploy airbags based on seat occupancy, weight, and position. The precise locations of these components vary by manufacturer and model year.

Common locations for the airbag control module (ACM)

ACM location varies by vehicle, but the following spots are among the most common starting points. If you need to locate it for service, consult your vehicle’s service manual for the exact diagram.

• Behind the glove box on the passenger-side dashboard (the most typical location in many cars).


• Under the center console or near the transmission tunnel (a popular spot in newer sedans and crossovers).


• In the right front kick panel or under the front passenger seat area in some models.


• In a few larger vehicles, the ACM may be placed toward the rear area or within a rear compartment depending on the airbag layout.

Note that ACMs are part of high‑voltage and sensitive safety systems and are typically accessible to technicians trained in airbag service.

Where the airbags themselves are located

The physical airbags are positioned at key protection points corresponding to common crash scenarios. Here are the typical placements you’ll find in most cars.

• Driver front airbag: housed inside the steering wheel hub.


• Passenger front airbag: located in the dash area in front of the passenger seat, usually above or near the glove box.


• Side airbags: mounted in the seat sides or door panels to protect the torso in a side impact.


• Curtain/roof airbags: installed along the interior roofline to shield heads during a rollover or side impact.

Airbag placements can vary by design and model year, but these are the standard locations in most modern vehicles.

Safety and service considerations

Never attempt to disassemble or tamper with airbag components yourself. If you suspect a fault or need to locate the ACM, contact a certified mechanic or your dealership. Always disconnect the vehicle battery and wait an appropriate amount of time (as specified in the manual) before working around airbag systems. Improper handling can cause unintended deployment or injury.

Model-specific guidance

To find the precise ACM location for your exact model, use the official service manual, manufacturer portals, or VIN-based parts databases. These resources provide model- and year-specific diagrams that remove guesswork and help ensure you’re looking in the correct place.

How to verify the ACM location for your car

Before attempting any search or inspection, review model-specific resources. If you’re unsure, rely on professional support.

• Consult the vehicle’s owner’s manual or a factory service manual for the diagram of the airbag system.


• Enter your VIN into a manufacturer’s parts database or service portal to pull exact location details.


• Ask a dealership or certified repair shop to confirm the ACM location and handling procedures before any work.

Having model-specific information minimizes risk and ensures proper handling of safety components.

Summary

Airbag components are designed to be discreetly tucked away. The airbag control module is commonly found behind the glove box, under the center console, or in the passenger kick panel, while the airbags themselves reside in the steering wheel, dash, seats, doors, and roofline. Always rely on trained technicians for any inspection or service involving airbag systems, and consult your vehicle’s documentation for model-specific layouts.

How do I know if my airbag control module is bad?

You can tell if your airbag module is bad by looking for the airbag warning light to stay on, which indicates a fault in the Supplemental Restraint System (SRS). Other signs include the airbag light flashing, a module that has been exposed to water or a crash, or diagnostic trouble codes related to internal faults or communication issues after a scan.

Signs of a bad airbag module

• The airbag light stays on: The airbag warning light should come on for a few seconds when you turn the key and then turn off. If it stays on, there is a problem with the SRS. 
• The airbag light flashes: A flashing airbag light can indicate a specific code or a disabled airbag. The pattern of the flashing can correspond to a diagnostic code, which you can look up in your owner's manual. 
• Diagnostic trouble codes (DTCs): A professional scan with an SRS-capable scanner can reveal codes that point to a faulty module, such as "B1000" for an internal fault or codes related to crash sensors. 
• After a crash: The airbag light may stay on after an accident. This can mean the module has stored crash data and needs to be reset or replaced, even if the accident seemed minor. 
• Water damage: If the module has been exposed to water, corrosion can damage the internal electronics and trigger the warning light. 
• Physical damage: Visible damage to the module itself can indicate it's faulty.

What to do

1. Don't ignore the light: A constantly lit airbag light means the system may not deploy correctly in an accident, so it's crucial to get it checked. 
2. Get a professional scan: Use an SRS-specific scan tool to read the diagnostic codes for a more precise diagnosis. 
3. Inspect the wiring: Check for any visible damage or corrosion in the wiring and connectors. This can be a cause of a faulty system. 
4. Seek professional help: A qualified mechanic can accurately diagnose the issue. They will know how to safely check the module, its connections, and other components like the clock spring. 

Where is the airbag module located?

The location of the airbag module can vary based on the make and model of the vehicle. However, it is commonly found in the center console, beneath the front seats, behind the steering wheel, or within the dashboard.

Can you reset an airbag control module?

Using a Diagnostic Scan Tool: Connect the diagnostic scan tool to your vehicle's OBD-II port, usually located under the dashboard. Follow the tool's instructions to navigate to the airbag system and perform a reset. This method is quick and can be done at home if you have the right equipment.

What happens if you unplug an airbag module?

If you accidentally disconnect an airbag connector, the airbag system will likely detect a fault, and the airbag warning light will illuminate. This could prevent the airbag from deploying in an accident. The connector should be reconnected, and the system reset by a professional technician.
