Airbag Warning Light reset successfully on 97 Nissan Sentra GXE.
I used the method of turning on the ignition, then immediately pressing the driver's side dome light activator switch on the inside of the door frame. I pressed it seven times then turned off the ignition. I repeated this again. Then I turned on the ignition and the airbag light was no longer flashing.
My thought from reading these posts is that the general idea is to do something which causes the computer to enter diagnostic mode. When it then checks out the airbags, it realizes that the airbag system is OK and turns off the light. There may be many ways to trick the computer into entering diagnostic mode.
Our experience is that the dealer hooks up their diagnostic equipment, comes back with a code, and then if you insist, resets the light. We did this once with the dealer for a charge of $110.
The dealers remarks were: "92285 Connected consult and retrieved bad A Sensor / Diagnostic Unit code. Needs new. In Stock. Est $625.00"
They could not (would not) disassemble the system to see if the airbag sensor was really bad. So we had them reset the light. It did not turn on again for 3 1/2 years.
A friend who is an excellent mechanic says that there are two accelerometers in the system. If they do not agree the computer turns on the light. This can happen by a jolt (or the dealer says: even bad weather). The accelerometers can later agree, but once the computer turns on the light, it stays on until the system is checked. What I think we are doing here is forcing the computer to re-diagnose the system.
Bottom line is it works. If the airbag light keeps coming on then you might have to wonder if there is an actual problem which needs to be fixed. But for us it has happened twice if 7 years.
Hope this works for you, too.
