How to Reset 2002 Buick Century Airbags

Your 2002 Buick Century, like most modern cars, has a computer system known as the On-Board Diagnostic to identify malfunctions. It also keeps track of the regular maintenance needs of the vehicle. When you see the SRS light illuminate on the instrument panel, this is to alert you to a malfunction with the Supplemental Restraint System or airbag system. Do not drive the vehicle; have it looked at by a professional mechanic as soon as possible. Once the Buick has been repaired, you or your mechanic will need to reset the airbag light. To do this, you need an OBD II scan tool.

Instructions

1

Put the key into the ignition and turn it to the "Run" position, but dont crank the engine.

2

Locate the diagnostic port under the steering column and plug the OBD II scan tools connector into this port. Wait while the scan tool powers on. Some scan tools need to be manually turned on. If so, look for the "on/off" switch and turn it on.

3

Select the "Read Codes" command on the scan tool and then "Clear Codes." Wait while the scan tool clears the SRS code. The scan tool will either return to the main menu or display the word "OK."

4

Unplug the scan tool and start the engine. Verify that the SRS light has shut off of the instrument cluster. If so, the vehicle is safe to drive.
