On most vehicles, the airbag light should come on for @6 seconds, and then go off if the system is working properly. If there is a fault or a problem in the system, the light will remain illuminated, or flash continuously. If the airbag light does not work properly, some vehicles have an audible tone that sounds indicating a problem with the airbag light system. When the light is on (or the tone is sounding), the airbag will NOT deploy, even in an accident.

The flashing light on your car is telling there is a problem. On some vehicles, the light is flashing a two digit code. Your vehicle will require a scan tool for the proper diagnosis, (and not the scanner at Auto Zone…airbag systems cannot be ready by that scanner) but here's a site that will explain everything you need to know about airbag lights and resetting the system. Once you know the code, you can most likely repair it yourself. There are fairly easy procedures that most people are capable of repairing.
Airbagsolutions.com has the fault code charts to tell you what is wrong! Although it’s a pay site ($14.95/day), it’s a lot cheaper than going to the dealer.

Some vehicle manufacturers accommodate systems without a scanner (like Toyota, Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) . Most all other vehicles require a scan tool for the diagnosis. Here is a link to the list of vehicle and scanner requirements.
Check out these websites also for more info on airbag systems and the light.
Lastly, check your vehicle for recalls through this link.

Did you turn it OFF before jacking it up?

1. The back of your car is low and the air suspension light is on. Check your fuse first. If its not the fuse check the air suspension switch in your truck, and make sure it is on.

2. You took it in for service and it was put on a lift or jacked up. And now the bags are full, and the car rides rough. Well you should have shut the switch in the trunk off before lifting the car. Now you will need to bleed the air out of each bag manual and reset your system.

3. You suspension is all the way down. This could be caused by a leaking or stuck valve or a leaking air bag. If it is a leaking airbag, they will all go down, as the car attempts to level itself. So you will need to watch for the one that goes down first as that should be the one with the leak.

4. Your car goes down overnight, but comes up when started. This could be something electronic or could be a leaking bag. Which will soon cause the compressor to go out.

I have a 1996 Lincoln that presented a "Check Ride Control" warning one morning. After driving it for about 10 minutes I could tell it was handling differently. By the time I got to work (50 miles) the front of the car had sunk such that the tires would scrape the inside of the fender when I made a turn. When I left work 10 hours later, the drive home was scary - I probably should have had it towed. The car over-reacted to every bump and each flaw in the road felt like a canyon.

After reviewing it for an hour or so, my mechanic said that the air system itself was mechanically OK but the computer was telling it the ride control to empty the cylinders. He talked to a local dealer and they said they wanted no part of it and that if they were to address the problem I could expect at least $1200 in charges.

Thankfully my mechanic isloated a flawed sensor - it cost me $168 for the part and $230 for labor. I was happy to get away with the $398.

My understanding is that these systems are really problematic and owners with the time and inclination often replace the air system with a spring suspension system.

- From my friend

It can be but I do not think you should because your ride will not be the same and you will not save any money. You can buy either the coil spring conversion or a new *pair* of air springs here >> I have bought from them many times. >> www.Strutmasters.com

Yes you can but it will change the feel of the ride. I replaced my whole system; bags, driers, hoses and compressor for less than a thousand dollars and it feels real good.

You have to remove and inspect the a/c compressor to inspect it. Try the AutomD Negotiator ( http://www.automd.com/negotiator/) feature on this site it is free. They will call local shops for the repair that you needed and send the multiple quotes from your local shops. So you can compare job prices within your area.

you can use the obd2 can bus air bag reset tool to reset it.

Find the relay first, unplug it, clean it the plug it back in. Try this before buying a compressor or a new relay. I remember in a car my friend was working on, it was on the RH (Passenger side) between the bumper and headlight. This happened ages ago so i cant recall what car that was. if that doesnt work

Air Leaks

Fill the water bottle with water and then put a few drops of soap in the bottle.

Squirt the soapy water onto the air fittings to test for leaks. If the fitting bubbles up, then you have a leak in that corner. In that case, tighten the fitting with a wrench, or remove and reinstall the fitting with thread sealant.

Undo the fitting with a wrench. Apply two wraps of Teflon tape around the fitting, then tighten the fitting and test again.

If the fitting still leaks, you may have a cracked fitting. Replace the fitting and reinstall, then test again.

Pressure Switch
Check the pressure switch in the air system. Often if the pressure switch isn't working, the air supply isn't being filled, and therefore your vehicle won't lift. Test by jacking up the vehicle in the air and setting on jack stands.

Drain the air tank. Generally there is a drain plug at the bottom of the tank.

Turn on the vehicle so that pressure switch should activate. Place a test light on the wiring. It should show a light on both connections. If it doesn't, check the fuse. Replace if necessary

Replace the pressure switch if the fuse is functioning properly but the switch still doesn't turn on.
Testing the Compressor

Test the compressor for power if the pressure switch is working but the tank is not filling up with air.

Place the test light on the power lead to the compressor(s). If it doesn't get power, check the relay running power to the compressor or the fuse running to the compressor.

If the fuse is bad, replace it and test again. If it's good, test the relay with the test light. If it doesn't work, replace it.

Check the air ride switch in the trunk, if u had car worked on recently, the tech may not have shut switch off before lifting vehicle which could blow out the rear air suspension. try flipping the switch to on position, listen to see if pump engages and if car lifts...

It is likely that the air bags are leaking and need replacing. I have replaced many of these with the same exact symptoms. Unless you tell me in response that the air bags have been replaced already (you would not have left out that detail I don't think) then the cause of the problem is the air bags leaking at the part of the bag that rolls over on to it self. There will be cracking on the surface that will foam up with very tiny air leaks if you spray the bags with Windex. Probability is greater than 90%.

My summary on this is to replace the air springs because you know you need them no matter. See what happens. It's not like you changed air springs that were good.

The only place I have used to buy air springs cheap and the valves are separate by the way (because just about everyone else except the Ford dealer does not even list them) is this place >> strutmasters.com

Yes, as long as the fluid states Mercon ATF - it can be interchanged in the power steering system.

sounds like cv joint boot is broken
