If the light is flashing there is no resetting it. One or more of the pressure sensors has failed. Replace the faulty sensor, set the correct tire pressure on all 4 tires. Take it for a short drive and the light will reset itself. If the sensors are 4-5 years old the batteries are probably dead or going to die soon. Replace all the sensors and be done with it.
