I should point out many times the srs light comes on after driving over bumps in the road. Parking lots with speed bumps sometimes flash srs light for a second only. The connector under the dash gets shaken in these bumps and can cause the light to come on. Keep in mind that if the reset does not work you need to track the problem down. In many instances, it is the seatbelt mechanism. These get dirty as dirt dust falls into the slot and collects. This becomes an issue over time and can interfere with the button inside preventing it from depressing when a seatbelt is clicked into the mechanism. Sometimes blowing compressed air into the seatbelt receiver portion will dislodge the build-up or obstruction other times you have to open it up and clean it out with soft toothbrush so the button can depress and make the electrical contact to prevent dash light coming on.
