Service air bag light on. Limits the car to 90 mph

I was told it was a air bag suspention problem. Something to do with the shocks or something about the raising and lowering of the suspension due to speeds and handleling. While driving the dash lights up service air bag, Limited to 90 mph. Is what I was told correct? Thank u for any help and advise. Also when I hit a ridge in the road the front end rattles but mostly just going straight. Is this my struts, tirods ext?

    Thank u. ActuallyI believe this car was in a front end collision so while being fixed it probably messed with the sensor like you informed me. The sensor ight does come on though as soon as I start the car.

HI, First off, it's hard to say what is causing the rattling under your car (for anyone, even a tech driving your car), so the best way to find out is to have it put on a lift and checked. Many service centers that sell shocks adn struts will take a look for you, mostly because it's a potential job for them. Any shop that would charge you to do this is not the place you should be taking it to. Second, in the STS, while there are airbag sensor problems reported occasionally, the sensors are usually the ones behind the front bumper. Is it possible that the person who told you this may be talking about the "shock" (hydrolic piston) that the front bumper is attached to? The sensors are right there, and maybe they mean that a bad piston can create a problem with the airbag sensor. That sounds accurate. As far as while you're driving, the sheer forward air pressure forced against the front bumper may be setting off the faulty sensor warning. It's speculation at this point, but it just may be the problem. You can take care of these individual things in a measured way, and avoid paying for unnecessary repairs.

    Yeah, the part about being in a front end collision pretty much seals my belief that the electronics simply were not installed to factory standards. This is pretty common with cars that have had a front end accident. You can still make the problem go away. But now that you've furnished me with the information, I'm wondering if the airbag works at all - or if it has even been replaced. The sensor that comes on may be informing you that the airbag itself is faulty. If you are relying on the belief that your airbag will deploy in case of an accident, I urge you to have the bag and sensors checked. Take care.

I added air shocks to my 1995 lincoln town car because the air suspension bags died. what pressure should they take and do they lose air so you have to add air?

The Stock Air Bags self Leveled, your new System should have come with PAperwork or is there a Air Nozzle that you have to fill? The Bags should come with a Pressure Window for a Firmer Ride or Softer Ride.

1996 toyota cavalier, air bag light on after battery went flat and new one installed.

That's odd ,better get the code read ,not sure who put the battery in ,
but if it got bumped or hit,it may have set off one of the sensors.
Which means you are sitting in front of a loaded gun.There are several
sensors that have to trigger to set the bag off,but if one gets triggered,
and the bag doesn't go off it will turn the light on.
Check the air bag fuse ,maybe somebody "sparked" something when the battery was changed.

It may be helpful for you to get some idea of the mechanism involved in operating the shock absorbers in your vehicle. Refer this information. It may then be a matter of finding the parts involved if replacement is required

Something is causing the back end of the car to sit several inches lower than the front end.

If the vehicle has air suspention in the rear it may have one of these problems. bad sensor- pump-air line- shock. you should take it to a qualified repair shop.

Service air bag light on. Limits the car to 90 mph!!!

Your air bags are for when you crash, unless youre driving a custom lowrider. An air suspension system problem doesn't have a light, just a fault code in the computer system and will dispaly as a digital message. You'll need to take it to a shop with the proper equipment for diagnosing air bags in ordeer to have the light turned off.
The shaking is likely your half shafts and can usually be identified simply by examining the dust boots. If they're cracked or broken dirt will get inside and the bearings being quite sensitive and under a lot of 'pressure' will grind themselves into oblivion with small amounts of debris.

2003 Lincoln Navigator air suspension

I would recommend going to and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. Airbags and compressors are constantly having to be replaced. Also something alot of people don't know is that theses air suspensions are not meant to be in temperatures above 90 Degrees or below 40 Degrees. That is most of the world. The temperature will cause you to replace alot of bags. and typically when your replacing a bag you are going to have to replace the compressor to because the bag had a hole or small crack in it causing the compressor to over work and it will die. I posted the link below so you can take a look I hope I was of some help Good Luck!!!

Air Suspension Light on - have replaced fuse many times plus new shocks.

your air compressor may not be working, or the air springs (air bag suspensions) may be leaking air.
