You’re driving to work, everything feels normal, and then it hits you — that little airbag light pops on. Maybe it’s steady. Maybe it flickers. Either way, your stomach drops.
We get it. At L&D Solutions, we work on airbag modules, seat belts, and SRS systems every single day. And one thing we know for sure: that light never comes on “just because.”
There’s always a reason.
Sometimes it’s minor.
Sometimes it’s serious.
What you don’t want to do is ignore it.
Here’s the thing: when your airbag light is on, it means your car’s safety system has disabled itself. If you get into a crash right now, the airbags may not deploy. And if they do, they might deploy at the wrong time.
So let’s walk through this the way we would if you were standing in our shop asking, “Why is my airbag light on, and how do I reset it?”
We’ll break down the top five causes, how you can diagnose it, and when to let our team handle it, safely and correctly, without the dealership markup.
Understanding What the Airbag Light Really Means
Your car’s airbag system is part of a bigger package called the Supplemental Restraint System, or SRS. Think of the SRS like the brain and nerves of the safety system — airbags, seat belts, crash sensors, and the control module all talking to each other.
When anything inside that network isn’t working right, the system throws a code.
That code turns on the airbag light.
Here’s what that really means:
- The system detected a fault.
- It shut itself off to prevent damage or accidental airbag deployment.
- Airbags will likely not deploy until the problem is fixed.
- You can’t “just clear it” until the underlying issue is gone.
We see a lot of folks try the cheap OBD scanner trick. It might clear the light for a minute, but if the issue is still there, that light comes right back.
Let’s get into the real causes.
The Top 5 Reasons Your Airbag Light Is On
1. A Faulty or Locked Airbag Control Module
This is the big one.
We see it daily.
The airbag control module is the brain of the whole SRS system. When your car is in a crash, even a small one, that module records crash data. Once it does, it usually locks itself.
Here’s a story we hear often:
Someone comes to us after a fender bender. No airbags deployed, but during the insurance repair, the light comes on. They think it’s a sensor or loose connector. Turns out the module stored crash data and won’t reset itself unless you send it in.
That’s where our team steps in.
We specialize in airbag module resets.
Typical signs it’s the module:
- Airbag light won’t turn off even after repairs
- Trouble codes like B1193, B0101, or “crash data stored”
- Airbags didn’t deploy, but the light came on afterward
Dealerships will quote you $900–$1,800+ for a new module.
We reset the original unit safely — and fast.
2. Bad or Stuck Seat Belt Pretensioners
This one surprises people.
Modern cars don’t just rely on airbags. The seat belts have built-in pyrotechnic devices called pretensioners. They tighten the belt instantly during a crash.
When a pretensioner fires, or even partially triggers, it sends a code to the SRS system. That code keeps your airbag light on until the pretensioner is repaired or rebuilt.
We see this a lot after low-speed collisions.
The seat belts “lock up,” the light comes on, and the dealership says you need a whole new belt setup.
Not true.
We rebuild seat belt pretensioners and retractors every day:
If you hear clicking, no movement, or the belt won’t retract, that’s your culprit.
3. Faulty Crash Sensors or Impact Sensors
Airbag sensors sit behind the bumper, under the hood, and sometimes inside the cabin. They’re constantly waiting for impact.
Here’s the tricky part:
They can fail without a crash.
Common causes:
- Water intrusion
- Corrosion
- Bumper impact (like hitting a parking post)
- Old age
- Loose wiring
We had a customer whose airbag light came on right after a car wash. The impact sensor behind the bumper had rusted, and the pressure from the wash finished it off.
A bad sensor will always trigger the airbag warning light — and yes, it will disable the whole system.
4. Loose or Damaged Wiring Under the Seats
This is the one that drives people nuts.
Under your front seats, you have wiring harnesses for:
- Occupancy detection
- Seat belt sensors
- Airbag connectors
- Pretensioner wiring
Move the seat back and forth enough times, and something can loosen.
A lot of airbag lights start here:
- Kids kicking the wires
- Pets riding under the seat
- Sliding seats back aggressively
- Installing aftermarket heated seats
- Spilled drinks
We’ve seen spilled coffee short out a passenger-side occupancy mat and keep the airbag light on for months.
This is an easy fix sometimes.
Other times, the sensor pad in the seat goes bad and needs replacement.
5. Dead or Weak Battery (or Recent Jump Start)
This is the “sleeper cause” that gets overlooked.
When your battery:
- Dies
- Gets disconnected
- Gets replaced
- Gets jump-started wrong
…the SRS module may lose its stable voltage.
That can easily trigger the airbag warning light.
We see this all the time after winter — cold weather kills the battery, customer replaces it, and boom, the airbag light turns on.
The system needs consistent voltage.
A voltage drop can make the module think something failed.
Sometimes clearing the codes fixes it.
Sometimes the module flags internal errors that need a professional reset.
How to Reset Your Airbag Light Safely
Here’s where a lot of drivers get stuck. They try “DIY resets” they find online. Some of those tricks work — temporarily. But the light always comes back.
I’ll walk you through how we diagnose it properly.
Step-by-Step: What You Can Check Yourself
1. Check the battery voltage
Weak batteries cause false SRS codes.
If your battery is under 12.4 volts, charge it and see if the light goes away.
2. Inspect wiring under the seats
Slide both seats forward and back.
Gently push wiring connectors into place.
If the light flickers, you found your issue.
3. Scan the SRS system
You need a scanner that reads airbag/SRS codes, not just OBD codes.
Look for codes like:
- B0010 (driver airbag fault)
- B0020 (passenger airbag fault)
- Crash data stored
- Pretensioner faults
- Occupancy sensor faults
Take a picture of the codes — they matter.
4. Try clearing the code once
If it comes back immediately, the issue is real.
If it stays off but returns days later, something is intermittent.
When You Should Stop DIY and Call a Pro
Here’s the truth: you cannot safely “reset” an airbag light if the cause is still there.
And you absolutely should not try to bypass or trick the SRS system.
Call a professional when:
- You see crash data stored
- Your seat belts won’t retract
- Your module was in a collision
- The same code keeps returning
- You replaced the battery and the light stayed on
- You don’t want airbags disabled while driving
This is where we come in.

Why Ignoring Your Airbag Light Is Dangerous
We see it all the time — people driving for months with the light on, thinking it’s “just a sensor.”
But here’s what they don’t realize:
When that light is on, your entire SRS system is shut off.
That means:
- No airbags
- No pretensioners
- No safety deployment
- No crash-time protection
Your car is basically driving without a safety net.
Even a 10 mph collision can cause injuries without airbags or proper belt tension.
We’re mechanics. We see the aftermath.
We’ve worked on modules pulled from cars that should’ve protected the driver — but didn’t — because that light was ignored.

FAQ: Airbag Light Questions People Ask Us All the Time
Can I drive with my airbag light on?
You can, but you really shouldn’t. When the light is on, the airbags and pretensioners are usually disabled. In a collision, they won’t deploy.
Will disconnecting the battery reset the airbag light?
No. The SRS module stores crash data and faults. Disconnecting power doesn’t erase stored issues.
Can an OBD2 scanner reset the airbag light?
Only if the underlying issue is fixed. If crash data is stored, or a sensor is bad, the light will stay on.
Is it cheaper to repair or replace the module?
Repair/resetting is almost always cheaper. Dealerships replace modules. We restore them.
How long does it take to reset an airbag module?
Most customers get their module back in 24–48 hours once we receive it.
