why would the idiot light for airbag come on?

  • Sponsors (?)


This just came up a little while back. I believe the conclusion was that the air bag light will come on when an air bag sensor is not working. This means that the air bag will not deploy in a collision.
 
Be careful with those sensors. You don't want it going off while you're playing with them. If that turns up nothing that power supply might be bad. It's located underneath the dash on the passenger side. Let me know if you want help finding it. I have my dash apart and can take a pic showing it...
 
There's a diagnostic monitor system for the airbag that controls everything located behind the heater/AC control panel. It completes a self test everytime the ignition is turned on. If there is a fault in the system the Air Bag light will stay on and the system is disabled until the problem is fixed. There are 4 sensors. 1 behind each headlight, 1 behind the grille bolted to the radiator support and the 4th one is in the passenger compartment behind the trim panel in the left side B-pillar.

My air bag light used to flash constantly. After a while it stopped (bulb burned out probably) and than a beeping noise started coming from the dash. It's pretty annoying.

I have the same problem on my 91 coupe. When I turn the car on, a beeping noise comes from the dash. It beeps four or five pulses at a time for about two or three sets. Then about twenty minutes later, it happens again. I thought it was from the stereo being that it seems to be coming from that area. Anybody know what that is from? My airbag light goes on when I start the car but then goes off. The beep is pretty loud.
 
The beeping is one of the fault signals for the airbag. Not sure which fault. There is a bunch of faults. The "AIR BAG" light will stay on or it will flash or the beeping will happen. They all represent different faults with the airbag sysem.

Thanks for the help. What exactly does this mean and how do I fix it? As I said earlier, my air bag light does not stay on. I really appreciate you shedding some light on this problem.
 
Thank god I am not the only one driving around with a flashing airbag light. Does anyone know how much the local dealer charges for airbag diagnostics? If its more than the cost of a new Grant steering wheel...
 
The other day on the drive home from work, I took one of the corner's in a "spirited" fashion. It was raining so the rear end swung out a bit on me. About 5 seconds later after I straightened the car out, the Air Bag idiot light starts flashing at me. It does this for about 10 seconds and then stays on steady! Now I'm saying WTF!?!? :shrug:

At the next traffic light, I shut the car off to see if that would reset the light. Sure enough the light stayed out after I started the car again. It hasn't flashed at me since then, so obviously it was the minor skid that caused it to flash initially.

Has anyone else experienced anything like that before? If so, do you know why the air bag light was flashing at me and then stayed on?
 
Reviving an old post...mine came on yesterday, did the flashing crap, then pause, flashing, pause...I was on an open road with no one around, cut the car off, turned back on, light still doing it.

Did anyone ever find out the cost to have it looked at/fixed by Ford stealership?

I remember reading something about being careful abut touching the airbag fuse - is it something you can safely take out, inspect and replace without making the bag go off and break your neck?
 
probably a bad clockspring , its a piece that goes on the steering column that is common to wear out on these cars , cost close to 100 bucks at the dealer , installs easily behind the airbag and steering wheel
 
Air bag codes can't be rear with a code scanner. You have to count the number of times it flashes to get the code. Mine has a code 34 right now. 3 flashes, a short pause, then 4 more flashes. Then it starts over. Most common cause for the airbag light is a bad clockspring, located behind the steering wheel. Usually it will flash a code 32 when the clockspring is bad. Mine is showing driver side airbag circuit shorted or low resistance, haven't got around to fixing it yet...
