To reset the service engine light on a 2003 Chevy Trailblazer, you can use an OBD-II scanner to clear the trouble codes. Alternatively, you can disconnect the negative battery cable for about 15 minutes to reset the system. After reconnecting, ensure that the light is off; however, if it reappears, it indicates an underlying issue that needs addressing. Always consult a mechanic if you're unsure about the cause of the light.
