Nissan Repair: AIR BAG WARNING LIGHTS COME ON? BUT NOTHING IS WRONG WITH IT..., nissan frontier, nicoclub

Question
I have a 2004 Nissan Frontier XE King Cab AUTOMATIC... this is how the situation exactly occurred... I was getting the deck for my stereo kit changed at my cousin's house. When he was finished changing my stereo kit, I noticed that the air bag warning lights keeps on flashing. I figured out that the reason that it is flashing is not because there is something wrong with the air bags, but it's because my cousin wasn't suppose to pull the PASSENGER AIR BAG SWITCH OFF while the ignition was on or it will cause the warning lights to flash (according to the owner's manual). Now my question is... how do I make this annoying light stop flashing since there is nothing wrong with the air bags? I already tried disconnecting the battery cables to see if everything will start over, but it didn't work. SUGGESTIONS PLEASE?

Answer
Jenny,

This is how the guys do it from the NICOCLUB on line.  I have not used the on car procedure before so I do not know if this will work.  I use a consult II and it takes a minute to do.  

First, turn on your car (ON key position) and your airbag light stays on for 7 seconds, then starts flashing every half second. (.5 seconds on, .5 seconds off, repeat)
This means either your airbag is malfunctioning, or it malfunctioned in the past. We'll find out exactly what happened in a second.

If your airbag light is on solid the whole time, either your airbag has deployed, the computer thinks its deployed, or your sensor or wire harness is broken. You're going to need a professional to fix this.

If your light never comes on at all, your METER fuse might be blown, or you might have a wiring fault in an airbag circuit. Go directly to Infiniti and have a professional fix this.

OK, so your light is flashing like I explained before. Next, we're going to enter DIAGNOSIS mode. This mode will tell you exactly what’s wrong with your airbag (according to the computer at least) It's a bit tricky, but read carefully.

1. Turn ignition switch “ON”.
2. After “AIR BAG” warning lamp lights for 7 seconds, [i.e. when it stops running solid and starts flashing] turn ignition switch “OFF” within 1 second. [DO NOT SWITCH IT TO LOCK, SWITCH IT TO ACC]
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 two times. (Perform 3 times in total.)
5. Turn ignition switch “ON”.
SRS is now in Diagnosis mode.

Try it a few times. If you can't get it to work, have someone else try. If you STILL can't get it to work, check your battery voltage. It might be low.

In diagnosis mode, you're going to hope the light flashes slowly. 2 seconds off, 3 seconds on, and repeats. If your light does this, this means that the computer detected a previous error that hasn't been erased. This is good.

If you get ANY OTHER result, go directly to Infiniti. You've got a real problem that needs a real fix.

Now, to erase the error from memory.

5. If “AIR BAG” warning lamp operates as [as I said before], turn ignition switch “OFF” to reset from Diagnosis mode
to User mode and to erase the memory of the malfunction.

6. Turn ignition switch “ON”. “AIR BAG” warning lamp operates in
User mode. [it should stay on for 7 seconds, then go off, like normal.]
