How do I reset the service tire monitor light? on 2007 Chevrolet Trailblazer

My service tire monitor light is on. Everything appears and sounds fine with the right front tire which it indicates is the problem. How do I fix or reset this?

check the tire pressures and make sure they all match according to the drivers door placard.
if the light persists, there may be a malfunction with the sensor itself.

This might be a problem with the TPMS sensor itself. Take your vehicle to a reputable tire store and have them try to reset the system for you. If the TPMS system will not reset per the reset procedure, a sensor may have failed and need replaced.
