You’re driving home after a long day, and bam! A deer jumps out of nowhere. Thankfully, everyone is okay, but your airbag light is on. Now you’re stuck with that annoying blinking light and a growing sense of dread whenever you start the car. You’ve heard whispers about resetting airbag lights with OBD scanners. Could this be the easy fix you’re hoping for?
Let’s dive in and see if an OBD scanner can be your knight in shining armor (or at least save you a trip to the mechanic).
Understanding the Airbag Light
Before we get into the nitty-gritty of OBD scanners, let’s talk about that little light glaring at you from the dashboard. The airbag light is more than just an annoyance; it’s a critical safety feature. When it illuminates, it signifies there might be an issue with your car’s Supplemental Restraint System (SRS), which includes airbags, seatbelt tensioners, and impact sensors.
Think of it like your car’s nervous system sending you a signal. Ignoring it? Well, that’s like telling your brain to ignore a sprained ankle – not the smartest move.
OBD Scanners: Friend or Foe to the Airbag Light?
OBD scanners are handy tools, like having a mini-mechanic in your glove compartment. They plug into your car’s OBD-II port (usually under the steering wheel) and read diagnostic trouble codes (DTCs). These codes are like your car whispering, “Hey, something’s not right here.”
But here’s the catch: while OBD scanners can read airbag-related codes and give you a clue about the problem, they often can’t reset the light. It’s like reading a restaurant menu – you know what’s wrong (you’re hungry!), but the menu can’t actually cook you a meal.
“Many people believe a simple scan and reset will solve their airbag light issue,” says John Miller, a veteran auto-electrician and author of “Understanding Your Car’s Electrical System.” “However, it’s crucial to remember that the airbag light is a safety feature. Simply erasing the code without addressing the root cause is like putting a band-aid on a broken bone.”
What Can an OBD Scanner Do for Airbag Lights?
While not a magic eraser, an OBD scanner can be a valuable ally in diagnosing airbag issues:
- Identify the Problem: OBD scanners can pinpoint the source of the airbag light, whether it’s a faulty sensor, a wiring issue, or a deployed airbag. This information is gold when you take your car to a mechanic.
- Clear Codes After Repair: Once you’ve fixed the underlying problem, an OBD scanner can clear the codes and turn off the airbag light.

Why You Shouldn’t Ignore the Airbag Light
Ignoring the airbag light is like ignoring a flashing “danger” sign – you’re putting yourself and your passengers at risk. A malfunctioning airbag system can have serious consequences in an accident, leading to:
- Increased risk of injury: If your airbags don’t deploy in a crash, the chances of serious injury increase significantly.
- Malfunctioning during an accident: In rare cases, a faulty airbag system might deploy unnecessarily, causing an accident.
- Legal ramifications: Driving with a known airbag light issue might lead to fines or complications with insurance claims in some areas.
Beyond the OBD Scanner: Next Steps
If your airbag light is on, resist the urge to simply reset it with an OBD scanner. Here’s a better approach:
- Scan for Codes: Use an OBD scanner to identify the problem.
- Research the Codes: Look up the codes online or consult a repair manual to understand the issue.
- Seek Professional Help: Airbag systems are complex. If you’re not comfortable working on them yourself, take your car to a qualified mechanic specializing in SRS repairs.

FAQs About Airbag Lights and OBD Scanners
Can a low battery trigger the airbag light?
Yes, a low battery can sometimes cause the airbag system to malfunction and trigger the warning light.
Will disconnecting the battery reset the airbag light?
While disconnecting the battery might temporarily turn off the airbag light, it’s not a reliable fix and won’t address the underlying issue.
Can I reset the airbag light myself?
While some people attempt DIY fixes, it’s generally not recommended. Airbag systems are complex and potentially dangerous if handled incorrectly.
