Hi all!
Recently I had to replace a light bulb in the switch trio ( a/c, directional and temp switch) and I did an operational check before I put the dash back
together. I did not plug the harness back in for the passenger airbag "off" indicator when I did the opps check, now I have a flashing red light on the dash that says "airbag". Can the computer that controls the airbag be reset? If so how? Thanks in advance
JLC

One bad thing about the service manual (for me anyway) is that it seems to take forever to find stuff. I'll keep looking for a computer reset, but how about the old fashioned method of disconnecting the battery for a while?

Thanks for the help, I was affraid that if I disconnected the battery some other computer would be affected that would cause the engine to run differently or some other side effect. I can try it tho. Any other ideas??

I have a 1999 Nissan Frontier 4x4 3.3 liter v6 and the a/c in not working and I had it checked and the mechanic said the ecm (computer) is bad, but he hit it and the a/c came back on for a while. Does anyone know how to reset the ecm??????? I am hoping it might work? Any other ideas, a new comp. cost $800.00, I need any other solutions.

Okay, this is gonna sound odd, but this is how you get the warning light to turn off:
turn the ignition key to the on position, but DO NOT start the truck.
Next, open the door and click the dome light switch on and off 7-10 times.
Now, I am unsure if you either turn the key off next then start it immediately, or if you just start it, so try it both ways. I did this on my my bosses 99 Frontier and it worked, and it also worked on my 95 Sentra.

Thanks for the reply, but a few questions. I tried it but I have a dome light in the back of the king cab near the sliding glass window, and 2 map lights near the rear view mirror, which one do I use to turn off and on? Also, do I do it quickly or slow? One more, There is the switch on the door that turns on and off the back dome light, do I use that to push to turn on and off the light? Thanks again for the help, I hope this makes sense.

If you have the airbag light, it will show steady for a few seconds (the manual says 7 secs) after you turn the key from off to on (but not start) and then start to flash. Here is how to reset it:

1. Turn the key from off to on.

2. Watch the airbag light closely. It will stay on for a few secs. and then as soon as it blinks off (the start of the flashing), turn the key off instantly.

3. Count to 5 (1 Mississippi, 2 Mississippi . . . .)

4. Repeat steps 1-3 two more times until you have done the cycle three times.

5. Now turn the key on and watch the light. It will start blinking in a different, slower manner. This is diagnostic mode. You can watch this for a little while, no hurry.

6. Now turn the key off again, Count to 5 like in step 3 again, and turn back on. If the procedure worked, the airbag light will not be flashing.

If it does not work the first time, just repeat the steps again.

By dome light switch, I meant the one on the door frame, below the latch, NOT the one on the roof. Sorry I didn't get back to you sooner, but I have no internet and have to bum computer time off friends....

I used the key on/off to reset my blinking airbag light in my 05 frontier except I counted to 7 mississippi. When the light starts blinkning slow (diagnostic mode) start the truck, the light will then go off.

Thank you Guys, this is a great forum, I am new here, but it saved me $95.00+, which my Nissan Dealer up here in NYC had quoted me to reset the Airbag Warning Light. I have a Nissan Sentra 1998 GXE, all I had to do was to open the door, turn the key to the ON position (not start the car) then tap the door ajar (on the driver's side) button about 7 times in quick succession, before the Airbag light starts flashing, then turn the key off, and repeat the whole process again one more time, it went to the slow diagnostic mode flashing second time around, and the third time when I turned the key OFF and back ON again, the flash was gone :-) ..... Thank you ALL, worked like a CHARM :-D. God Bless You All and this Forum!

This method worked for me on my 2006 Frontier. Thanks for posting this info. Saved me $93 at the Nissan dealership.

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.
