2010-2011 Subaru Outback Air Bag Control Module: Replacement, Resets, and Recalls
This guide clarifies the critical difference between the Air Bag Module and the Body Control Module, and details the essential programming and reset procedures required after a collision.
- This part (98221AJ07A) is the Air Bag Control Module, NOT the Body Control Module (BCM).
- After any accident that deploys airbags or locks seatbelts, the module stores crash data and must be professionally reset or replaced; it cannot be cleared with a normal scanner.
- Resetting your vehicle's original module is the most cost-effective option and is plug-and-play upon reinstallation.
- A new or used module from a different vehicle requires expensive dealer programming to match your car's VIN.
Is This a Body Control Module?
No. A common point of confusion for owners and mechanics is the difference between the Body Control Module (BCM) — which Subaru often calls the Body Integrated Unit (BIU) — and the Air Bag Control Module. The part number 98221AJ07A is exclusively for the Air Bag Control Module. The BIU controls convenience features like power windows, door locks, and interior lights. This Air Bag Control Module is a dedicated safety computer for the Supplemental Restraint System (SRS) and has no other function.
Symptoms of a Bad Air Bag Control Module
The signs of a faulty Air Bag Control Module are serious and directly impact vehicle safety.
- SRS Airbag Warning Light: The most common symptom is a constantly illuminated airbag warning light on the instrument cluster. This indicates the SRS system has detected a fault and has been disabled. The airbags will not deploy in a crash while this light is on.
- Failure of Airbags to Deploy: The most dangerous symptom is being in a collision where the airbags should have deployed but did not. This indicates a total failure of the module or its related sensors.
- Locked Seat Belts After a Collision: After an accident, even a minor one, the module may trigger the seat belt pretensioners. This causes the belts to lock up and become unusable, and is a sign that the module has stored crash data.
Pro Tip: An SRS-capable OBD-II scanner is required to read the specific trouble codes from the airbag system. Standard code readers typically only access powertrain (P-codes) and cannot communicate with the SRS module.

NHTSA Recall: Takata Airbag Inflator
The 2010-2011 Subaru Outback is included in the massive Takata airbag recall, the largest in automotive history. This recall does not pertain to the Air Bag Control Module itself, but to the passenger-side front airbag inflator. These inflators can degrade over time, especially with exposure to heat and humidity, and may rupture during deployment, sending dangerous metal fragments into the cabin.
Subaru dealers will replace the front passenger airbag inflator free of charge. Until this repair is performed, it is strongly recommended that no one sits in the front passenger seat. You can check if your vehicle is affected by entering your VIN on the NHTSA or Subaru recall websites.
Programming and Replacement Requirements
Replacing an Air Bag Control Module is not a simple plug-and-play repair unless you are reinstalling the vehicle's original, reset module.
Warning: After any collision that is severe enough to deploy the airbags or lock the seat belts, the module stores permanent "crash data." This data cannot be cleared with a standard diagnostic scanner, even at a dealership.
Option 1: Resetting Your Original Module
The most cost-effective and straightforward solution after a collision is to remove your vehicle's original module and send it to a specialized third-party service. These services can erase the stored crash data, effectively resetting the module to its factory state. When you receive the reset module back and reinstall it in the same vehicle, it is plug-and-play and does not require any additional programming. This is because it retains the original VIN and configuration data.
Option 2: Installing a New or Used Module
If you install a different module (either brand new or used from a donor car), it must be programmed to your vehicle's specific VIN and options. This procedure typically requires a Subaru dealership and their proprietary diagnostic tools. A used module from a salvage vehicle will likely contain crash data from the donor car, which would still need to be cleared before it can be programmed and function correctly.
Buying a Used Air Bag Control Module
Purchasing a used Air Bag Control Module can be a good value, but it comes with significant risks if you are not careful. This is a critical safety component, and cutting corners is not advised.
- Verify the Part Number: For the 2010-2011 Outback, you must match the part number 98221AJ07A exactly. Subaru used different modules, and they are not interchangeable.
- Assume It Has Crash Data: Unless the seller explicitly guarantees the module has been professionally reset and cleared of crash data, you should assume it has it. Factor in the cost of a reset service (around $50-$100) to your total purchase price.
- Inspect for Damage: Never buy a module with any signs of physical damage, corrosion, or water intrusion. Water damage can cause hidden corrosion on the circuit board, leading to intermittent faults or complete failure.
- Why Used OEM is the Only Option: Aftermarket companies do not manufacture new replacement Air Bag Control Modules due to the safety-critical nature and complex programming. A used, reset OEM module is a reliable and common repair solution.
Replacement Cost Breakdown
The cost to resolve an Air Bag Control Module issue can vary dramatically based on the path you choose.
| Part / Service | Estimated Cost | Notes |
|---|---|---|
| New OEM Module | $340 - $510 | Part only. Does not include dealer programming and labor. |
| Used OEM Module | $40 - $100 | Part only. Assumes it will need a reset service. |
| Reset Service | $50 - $150 | Mail-in service to clear crash data from your original module. |
| Shop Labor (Replacement) | $150 - $300 | To physically remove and reinstall the module, which is located under the center console. | 🎬 Watch: How to locate and remove your SRS module for reset.
| Shop Labor (Programming) | $100 - $250 | Dealer-only service required for new or used modules. |
Frequently Asked Questions (FAQ)
Do I have to replace the module after an accident if the airbags didn't deploy?
It depends. Even in a minor fender-bender, the crash sensors can be activated and store fault codes that turn on the SRS light. In many cases, these "soft codes" can be cleared with a capable scanner. However, if the seat belt pretensioners fired, "hard codes" and crash data are stored, requiring the module to be reset or replaced.
Can I reset the airbag light myself?
You cannot reset the airbag light if it's on due to stored crash data (hard codes) just by disconnecting the battery. This requires a professional reset service. If the light is on due to a simple fault (like a loose connector or faulty sensor that has since been fixed), a specialized SRS-capable OBD-II scanner can clear the code.
Where is the Air Bag Control Module located on a 2010-2011 Outback?
The module is located under the center console, behind the gear shifter assembly and below the radio/climate controls. Access requires removing the center console side trim, the shifter trim, and other surrounding panels.

No. It is critical to match the part number exactly. While a part may look identical, the internal programming and sensor configurations can be different between model years, making it incompatible. For 2010-2011 models, ensure the part is 98221AJ07A.
