Airbag light in 1999 Nissan maxima kept flashing?

There are two solutions for this problem, that either is resulting from a harness ground or a loose connection between the airbag sensor plugs.

Try these the steps below

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 this doesnt work try

1. Turn ignition off.

2. Open drivers side door.

3. Locate the driver door switch (located on door post)

4. Turn Ignition on and press the door switch at lease 5 times within 7 seconds.

5. If light starts flashing quickly in a marker sequence you have an existing fault code.

if light continues to flash slowly, you have an itermittent problem.

Once you turn key off and restart vehicle the system will be reset.

It is very common to have the seat belt restraints lose their ground. Beware of replacing many of these components yourself, unless they are done properly you could set the airbag off.
