How to Reset the Airbag on a Chevy Avalanche

by Katebo

You can reset the airbag light on your Chevy Avalanche from your home garage, saving yourself money and a trip to the dealership. The airbag light, called an SRS or Supplemental Restraint System light, illuminates when there is a malfunction with the vehicle's airbag system. Do not drive the Avalanche if you see this light because the airbag could accidentally deploy while you are driving or possibly not deploy when you need it during an accident. You need an automotive scan tool, called an OBD scan tool, to reset the computer and shut off the SRS light. This tool can be obtained from any auto parts retailer.

Put the key into the ignition and turn it to the "On" position but don't crank the engine.

Connect the OBD scan tool's data cable to the Chevy's diagnostic port under the dashboard near the steering column. This is a 16-pin port.

Power on the OBD scan tool and find the PCM menu on the face of the scan tool. Use the arrow keys to select "Codes" and then "Clear All Codes." Wait for the scan tool to finish. It will indicate this by either returning to the main menu or displaying the word "OK."

Unplug the scan tool and start the engine. Verify that the SRS light has shut off.

Warning

  • A mechanic should inspect and, if necessary, repair problems with the airbag system before resetting the airbag light.
