If your airbag or SRS light stays on after startup, your vehicle detected a fault in the restraint system that can affect how airbags, seat belt pretensioners or sensors perform in a crash. We recommend treating it as a safety issue, not a maintenance reminder: limit driving, watch for other warning signs and get a diagnostic scan as soon as you can.
TL;DR:
- A low-voltage battery or recent electrical disturbance can trigger the airbag warning light without any actual system fault.
- Corroded wiring, faulty sensors, or control modules often cause the warning, but a diagnostic scan is necessary to identify the exact part.
- Recalling and repairing system faults early, especially through VIN-based checks for open recalls, can save money and prevent safety risks.
- Driving with the airbag light on is generally safe for short trips unless warning signs like smoke, collision damage, or multiple dashboard lights appear.
- Repairs typically involve wiring corrections, replacing sensors like the clock spring, or control modules, with recall remedies often covered under manufacturer warranties.

Common causes that make the airbag light turn on
The airbag light doesn’t tell you which part failed, only that the system found something it doesn’t like. That’s part of what makes guessing so risky: a lot of different components feed into the same warning lamp, and swapping parts without knowing the actual cause wastes money and time.
Here’s what tends to set it off:
- A damaged or corroded crash sensor, often near the front bumper or along a wiring harness
- A worn clock spring, the coiled wiring behind your steering wheel that lets signals reach the driver’s airbag
- A faulty seat belt pretensioner or seat occupancy sensor
- A control module issue or a communication fault across the vehicle’s network, which can trigger an SRS message even when the real problem lives elsewhere
- Corroded or moisture-damaged wiring connectors, or a low-voltage event after a drained or recently replaced battery
One more thing worth knowing: the passenger “airbag off” indicator and the SRS warning lamp are not the same signal. NHTSA explains that advanced occupant classification systems can change passenger-airbag status based on sensed seat loading, so that indicator switching off isn’t automatically a system malfunction. If the red SRS light stays lit, though, that’s the one that needs attention.
Is it safe to drive with the airbag light on?
Your car will probably drive just fine with the light on, which is exactly what makes this tricky. The issue isn’t how the car feels today. It’s whether the airbags, pretensioners and sensors will do their job if you’re ever in a collision.
Some signs mean stop driving and arrange a tow right away: smoke or a burning smell, multiple warning lights appearing together, visible collision damage, or any sign of electrical trouble like flickering dash lights. Short of those red flags, it’s reasonable to drive cautiously to a shop. Stick to lower speeds, skip long highway trips, and keep heavy items off the passenger seat since that can confuse occupant sensors even further.
How to diagnose an airbag light: owner checks, battery test and VIN recall lookup
Before you call a shop, a few quick checks can save time:
- Confirm both front seat belts are buckled correctly, since an unlatched belt can sometimes trigger a warning.
- Clear heavy bags or objects off the passenger seat, since weight affects occupant sensors.
- Note whether the passenger airbag-off light is on, since that’s a separate indicator from the SRS lamp.
- Check when the battery was last replaced or jumped, since low-voltage events are a known trigger.
A low or recently disrupted battery is one of the more overlooked causes of an SRS warning, and our battery light guidance walks through why a proper battery and charging test should come before any part gets swapped.
From there, the real diagnosis happens with a scan tool that reads SRS, body control, and ABS modules, since AAA notes that a fault in one module’s network communication can throw a warning that looks like an airbag problem but isn’t. It’s also worth running your VIN through the NHTSA recall lookup, a free tool that screens for open safety recalls going back 15 calendar years. It’s a smart first step, but it won’t replace an actual scan.
Common airbag light repairs and what they involve
Once a scan points to the actual fault, repairs usually fall into a few categories:
- Wiring or connector repair, often a cleaning or splice job rather than a full part swap
- Clock spring replacement, which involves careful work inside the steering column
- Control module repair or replacement, sometimes requiring programming to match the vehicle
- Seat belt pretensioner replacement, especially after a prior deployment or fault code
Pro Tip: Ask for your VIN-based recall results in writing before paying for a repair, since recall-related fixes are typically handled by the manufacturer at no cost to you.
Recalls are worth ruling out early for exactly that reason. If a documented recall covers the part in question, that repair path looks very different from an out-of-pocket fix.
When to tow instead of drive
A few warning signs mean you shouldn’t keep driving at all: smoke or a burning smell, several dashboard warnings lighting up together, a sudden change in how the car handles, visible crash damage, or sparks near the dash — which are explained in detail in Why Is My Car’s Dashboard Showing Warning Lights?. If you notice any of these, pull over safely, shut off the engine, write down your VIN and which lights are on, and call for a tow rather than risking the drive.
What to expect when we diagnose an airbag light
Our ASE-certified technicians start with a full diagnostic scan across the SRS, body control and related modules, paired with a visual inspection of wiring, connectors and seat belt hardware, plus a battery and charging check since low voltage is such a common trigger. We also run a digital inspection with photos, so you can see exactly what we found instead of taking our word for it.
A few things that help us move faster:
- Your VIN, so we can check for open recalls before touching anything
- A description of when the light came on and whether anything unusual happened first
- Photos of your dashboard if multiple lights are involved
We offer no-appointment walk-ins and same-day service when our schedule allows, and qualifying repairs come with a warranty.
Schedule an airbag light diagnostic with Express Lube & Car Care

Our ASE-certified technicians document everything with a digital inspection report, so you know what’s wrong and why before you approve a fix.
If you’re dealing with an airbag or SRS light in Richland Hills, we’re set up for walk-ins or appointments, and qualifying repairs are backed by a warranty. A few ways to get started:
- Browse our full list of services to see what we cover beyond SRS diagnostics
- Call us at (817) 284-8478 to describe your warning light and ask about availability
- Bring your VIN so we can screen for open recalls as part of your visit
Reach out and we’ll get your airbag system checked properly, not guessed at.
FAQ
What causes an airbag light to come on?
An airbag light usually points to a fault somewhere in the restraint system, which can include crash sensors, the steering wheel’s clock spring, seat belt pretensioners, wiring, or a control module. A low-voltage event, like a drained or recently replaced battery, is also a common trigger.
How do you fix the airbag light?
The fix depends on what a diagnostic scan finds, since the same warning light can mean a wiring issue, a sensor fault, or a module problem. A professional scan of the SRS and related modules identifies the actual cause before any repair or part replacement happens.
Can I still drive if my airbag light is on?
Short, cautious trips to a repair shop are generally reasonable unless you notice smoke, a burning smell, multiple warning lights, or signs of collision damage, in which case you should stop and arrange a tow. Even if the car drives normally, the restraint system may not perform correctly in a crash until the fault is fixed.
Is an airbag light expensive to fix?
Cost depends entirely on the cause, since a wiring repair is a very different job from a clock spring or control module replacement. A diagnostic scan narrows down the actual problem first, which helps avoid paying for parts that were never the issue, and we’re happy to go over cost once we know what your car needs.
What’s the difference between the passenger airbag-off light and the SRS warning light?
The passenger airbag-off indicator reflects occupant sensing, meaning it can turn on or off based on seat weight rather than a system fault, according to NHTSA. The SRS or airbag warning light, on the other hand, signals an actual detected problem in the restraint system and should be checked promptly.
