Airbag / SRS light

Airbag / SRS Light

Get this looked at soon. The car will drive fine, and that's the problem: nothing about how it handles will tell you the airbags are unreliable, so it's easy to put off. Don't put it off.

This light means the airbag control module has run its self-check and found a fault somewhere in the system. That could be an actual airbag, a seatbelt pretensioner, or one of the sensors and wiring that tell the system when to fire. When the module sees a fault, it usually disables the system rather than risk deploying it wrong. So a car with this light on may not deploy any airbags at all in a crash, or may deploy them incorrectly. There's no safe assumption to make here.

The common causes, roughly in order:

A seat occupancy sensor or seatbelt buckle switch acting up, especially on the passenger side. A loose or corroded connector under a seat, often from seat covers, kids' seats, or water getting in from a spilled drink or a wet floor mat. Sometimes it's the clock spring, the coil behind the steering wheel that lets the wheel turn while keeping the airbag wired in. Less often, it's the airbag control module itself, or damage from a previous minor collision that never got the airbag system reset or inspected afterward.

Fixing it starts with pulling the fault codes from the airbag module, which point to the specific circuit or sensor involved. From there it's usually a matter of checking connectors and wiring for corrosion or a bad connection, testing the seat sensors and buckle switches, and replacing whatever's actually faulted. If it turns out to be the clock spring or the module itself, that's a bigger job, but the diagnosis is what tells you which one you're dealing with. It's not a light where you can guess from a list and skip the diagnostic step. This isn't a job to skip: work like this touches whether the system fires correctly if you're ever in a crash, and we're not going to sell you a part swap without confirming what's actually wrong first.

Warning-light symbols and meanings vary by vehicle — always check your owner’s manual. This is general guidance based on what the light indicates, not a physical inspection, and a light on its own never names a failed part.
