Why doesn't Airbag warning light come on when you start up

Hi, on most vehicles, the airbag light should come on for at 6 seconds, and then go off if the system is working properly. If there is a fault or a problem in the system, the light will remain illuminated, or flash continuously. If the airbag light does not work properly, some vehicles have an audible tone that sounds indicating a problem with the airbag light system. When the light is on (or the tone is sounding), the airbag will NOT deploy, even in an accident. <br /> The flashing light on your car is telling there is a problem. <br /> <br /> <b>How to reset AIRBAG SRS Light on 2003 - 2006 Infiniti G35 Coupe </b> <br /> Ignition Key Method: <br /> <ul> <li>Turn IGNITION on (but don't start car).</li> <li>After the AIR BAG warning lamp lights for 7 seconds, turn IGNITION off within 1 second.</li> <li>Wait 4 seconds.</li> <li>Turn IGNITION on (but don't start car).</li> <li>After the AIR BAG warning lamp lights for 7 seconds, turn IGNITION off within 1 second.</li> <li>Wait 4 seconds.</li> <li>Turn IGNITION on (but don't start car).</li> <li>After the AIR BAG warning lamp lights for 7 seconds, turn IGNITION off within 1 second.</li> <li>Wait 4 seconds.</li> <li>Turn IGNITION on (but don't start car).</li> <li>Wait 3 seconds.</li> <li>Turn IGNITION off.</li> <li>Wait 2 seconds.</li> <li>START Car (the light may be blinking slower than before).</li> <li>Wait 3 seconds.</li> <li>Turn IGNITION off.</li> <li>Wait 3 seconds.</li> <li>START Car.</li></ul> <br /> <b>This is a little easier</b> To reset the light simply turn the iginition to the on position, (you dont need to start it). All the lights should stay on for thier diagnostic check. As soon as the airbag light goes off, before it starts flashing, immeditatly turn the car off. Repeat this 3 or 4 times (turning to on then off) and the light should go away
