How do you reset a air bag light on a 2004 Chevy silverado?

To reset the airbag light on a 2004 Chevy Silverado, first ensure that the vehicle is turned off. Then, disconnect the negative battery cable and wait for about 10-15 minutes to allow any residual power to dissipate. Reconnect the battery cable and start the vehicle; the airbag light should ideally turn off. If the light remains on, there may be a persistent issue that needs to be diagnosed with a scan tool.
