Your SRS warning light turns on. Your mechanic reads the fault code and names a faulty airbag module. A new part from the dealer costs more than you planned. A used OEM undeployed airbag from a seller such as Use OEM is a lower-cost option, but only when you pick the right part. This guide explains how to do that.

What Does the SRS Warning Light Mean?

Definition

SRS stands for supplemental restraint system. The light turns on when the system detects a fault in the airbags, seat belt pretensioners, sensors, or wiring.

What Happens When the Light Stays On

A lit SRS light means the system is not ready to protect you in a crash. A technician reads the fault code and identifies the failed component before any part is ordered.

When Do You Replace an Airbag?

After Deployment

You replace an airbag after it deploys. A deployed airbag is single use.

After a Fault Code

You replace an airbag when a scan points to a faulty module, a failed inflator circuit, or an open connector in the airbag itself.

After Physical Damage

You replace an airbag when a collision, water, or heat damages the module or its cover.

What Is a Used OEM Undeployed Airbag?

OEM Meaning

OEM stands for original equipment manufacturer. An OEM airbag is the same part installed at the factory. It matches the original design, connector, and mounting points.

Undeployed Meaning

An undeployed airbag never inflated. A seller removes the module from a donor vehicle, inspects it, and lists it with its part number. An undeployed unit keeps its full function.

Which Airbag Positions Exist?

Most vehicles carry several airbag positions. Each position uses a different module.

Front Positions

Driver Airbag

The driver airbag sits in the steering wheel hub. It protects your head and chest in a frontal crash.

Passenger Airbag

The passenger airbag sits in the dashboard. It protects the front seat passenger in a frontal crash.

Lower and Side Positions

Knee Airbag

The knee airbag sits below the steering column or in the lower dash. It protects your legs and holds your body in position.

Curtain Airbag

The curtain airbag runs along the roofline above the side windows. It protects your head in a side impact or rollover.

Seat Airbag

The seat airbag sits in the side of the seat. It protects your torso in a side impact.

Why Do Counterfeit Airbags Matter?

The Risk

The U.S. National Highway Traffic Safety Administration has issued warnings about counterfeit airbags. Some counterfeit units failed to deploy properly or released metal fragments. The NHTSA air bag safety page explains how airbags protect you and why a correct replacement matters.

How to Reduce the Risk

1. Buy from a seller who lists genuine OEM parts only.
2. Ask for photos of the part and its label.
3. Ask where the donor vehicle came from.
4. Match the part number to your vehicle.

How Do You Match an Airbag to Your VIN?

Match Factors

You match an airbag by VIN, make, model, year, trim, and part number. Airbags vary by trim level, steering wheel design, and production date.

Matching Steps

1. Read the VIN on the dashboard near the windshield or on the driver door jamb.
2. Find the part number on the label of your old airbag.
3. Confirm the airbag position, such as driver, passenger, knee, curtain, or seat.
4. Send the VIN to the seller and ask for a match confirmation.

Why Does a Certified Technician Install the Airbag?

An airbag contains an inflator charge and connects to the SRS control module. A certified technician follows the vehicle maker’s procedure. The procedure includes disconnecting the battery and waiting before handling the module.

After installation, the technician scans the SRS system and clears the fault code. The technician then confirms the warning light turns off. Incorrect installation risks a failed deployment.
