Chevy Airbag Light Stays On Troubleshooting Guide

Is your airbag light illuminated on your Chevrolet dashboard? Learn how to fix it by following the procedures below.

If the Chevrolet airbag light stays on and won’t turn off, it is because the Safety Restraint System (SRS) has detected a problem with one of the airbag components. Two possibilities include damaged wires or low voltage.

While the airbag light stays on, the SRS system will not function, and no airbag will deploy in case of an accident. Don’t ignore the airbag light. Get the airbag system diagnosed as soon as possible.

What Causes Chevy Airbag Light to Come On?

Chevrolet airbag light may come on due to several possible issues such as:

  • Low battery voltage caused by a dead battery
  • Passenger weight sensor defective
  • Previous accident
  • Deployed airbags
  • Faulty seat belts
  • Damaged crash sensor
  • Bad clock spring
  • Wiring harness damaged

How to Reset Airbag Light on a Chevy

Below you will find instructions on how to read codes from the airbag module and clear them appropriately.

For this procedure, you will need a Chevrolet Airbag Scan Tool. A generic OBD-II scanner will show no fault codes, even though airbag codes are present and the airbag light is on.

  1. Under your Chevrolet dashboard, you will find the Onboard Diagnostic port, also known as the OBD-II port.obd2 port location All 1996 and newer Chevrolet have this port.
  2. Plug your Chevrolet Airbag Scan Tool into the 16-pin OBD2 port. The trapezoid port allows the scanner to plug only in one direction.Connecting OBD-II Scanner

  5. Follow the prompting on the diagnostic scanner to select your model. Next, manually select the AIRBAG SYSTEM. Scroll down to read codes and scan your Chevrolet for airbag fault codes. If the codes you retrieve are PRESENT or CURRENT status, you will need to fix that problem before you can clear the airbag light.
  6. If the status of the codes is STORED or PAST, it is ok to clear the code. For example, an airbag fault code triggered by battery voltage can be erased once the battery has been recharged. After you clear, the Chevrolet airbag light, turn off the ignition, then back on to determine if the airbag light has been reset.
  7. Go back to the Airbag / SRS control unit.
  8. Scroll down to Clear / Erase Fault Codes and press enter.

If the problem hasn’t been fixed, the airbag light will return immediately or immediately after the problem is detected.

These instructions apply to Chevy Spark, Sonic, Bolt, Volt, Cruze, Malibu, Impala, Camaro, Corvette, City Express, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado, Sonic, Blazer, Astro, HHR, Uplander, Avalanche, etc.

Recall

Chevrolet has issued several airbag recalls over the years.

Find your VIN at the lower-left corner of the windshield and call any Chevy dealer to check if any recalls are open.

If there is an open recall for your Chevy airbag system, the dealer may fix that problem-free charge if related to the recall. The dealer will need to diagnose the vehicle and verify that the airbag light is on because of the recall.

Dealers are not responsible for fixing all airbag problems free of charge—only those related to the recall.

    If you have replaced the sensor.. has the problem been fixed?
    Sometimes, you might just see an error for a while.

    If the ACTUAL problem still remains remember that the B0091 code can mean 3 things

    1. Faulty Left Front Side Air Bag Satellite Sensor
    2. Left Front Side Air Bag Satellite Sensor harness is open or shorted
    3.Left Front Side Air Bag Satellite Sensor circuit poor electrical connection

    If you solved the 1st problem, check for the other two

    The airbag light on my chevy impala has been on for a few months. The dealer wanted $90 for diagnostics. And there are no open recalls for that car. So I knew I would have to pay for diagnostics plus the price of the repir who knew how much. I ended up getting Launch creader and scanned for the codes. It came with a code for passenger seat sensor. I was looking under the seat on the passenger side and found the connector disconnected. Pluged it back on and reset the airbag code with the scanner. Light is gone. Plus I have a scanner that I can use again on this and othe rcars. Thank you for this tutorial
