How to Reset the Airbag Light on your car
You can reset the airbag light on your car while working from home, saving yourself a trip to the now infamous kawaya. If you turn the ignition key on while you are installing a radio but you forget to plug in the airbag components, you will cause the airbag or SRS (Supplemental Restraint System) light to flash even after plugging it back in. You can reset the light easily in a few minutes without using any special tools.
Put the key into the ignition and turn it to the "On" position.
Wait for the SRS light to illuminate on the instrument panel. As soon as the light turns off, switch the ignition key to the "Off" position within one second.
Repeat Steps 1 and 2 two more times.
Turn the key in the ignition back on again and the light should now be reset. Start the engine to verify that the SRS light illuminates on the instrument panel for seven seconds, then shuts off for good.
