this is the code for the frontier, may work for you, i'm not sure.
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 ti
