My airbag warning light isn't coming on and it wont pass the nct.

Try going to an Autozone, Advance, or Oreilys autoparts store for a free scan. They may have a scanner which will read this warning and actually tell you what part is bad.

You may have a dirty bumper sensor(First try wd40 on it) or a problem with the airbag triggers inside the dash. Do not fool with the dash. It can deploy the airbags and then you are looking at injury and hundreds of $ to replace them.

Also, do not ignore the warning.

Change your airbag bit under stearing wheel light on dash does not come into effect on an mot

The light is on because of a code stored and will not reset till the code is cleared.The problem is ifsomething is damaged or a part has failed in the airbag system the light will come back on and you will need to make the repair in orderto keep the light off.

if the airbag light is on then its not a fuse ,most likely cause is the wiring under the seat or the serpentine winding under the steering wheel airbag ,try disconnecting the battery then cleaning the connection under the seat and also the plug into the pyrotechnic device on the seat belt anchorage.If you still cannot get it right then use a diesel preheater timer relay and connect the airbag light through this so the light goes out after a few seconds then vehicle will pass its vehicle mechanical inspection test

I have the same problem and it's not the rely or fuse... that would be too easy.

2000 Dodge Caravan ABS Light Question: 2000 Dodge Caravan. The other day my light for my air bag came on, but I noticed when it came on my cruise control stopped working and my horn doesn't work when I push on it. However the horn does work when you set off the alarm. Is it a fuse that's gone bad and if so which one is it.
Thanks for all your help.Christy
Answer: There is a device inside the steering wheel called a Clockspring. Basically it looks like the main spring of a watch. It's purpose is to insure perfect electrical contact with the airbag module in the steering wheel. Wiring for the horn and cruise control also go through the Clockspring. When the Clockspring goes bad you lose horn, cruise control and the airbag light comes on.
On 10/5/2004 a Motor Vehicle Recall, number 04V480000 was issued on this vehicle for this problem. From the recall bulletin:
Summary:
ON CERTAIN MINIVANS, THE DRIVER'S AIR BAG MAY BECOME DISABLED DUE TO A FAILURE OF THE CLOCKSPRING, WHICH IS LOCATED IN THE HUB OF THE STEERING WHEEL.
Consequence:
THIS CONDITION WILL MANIFEST ITSELF THROUGH ILLUMINATION OF THE AIR BAG WARNING LAMP, AND COULD EVENTUALLY RESULT IN A DRIVER'S AIR BAG OPEN CIRCUIT, IF THE PART IS NOT REPLACED IN A REASONABLE AMOUNT OF TIME.
Remedy:
DEALERS WILL REPLACE THE CLOCKSPRING ASSEMBLY ON ALL COVERED VEHICLES WITH 70,000 MILES OR LESS. FOR THOSE VEHICLES WITH MORE THAN 70,000 MILES, DAIMLERCHRYSLER WILL OFFER AN EXTENDED LIFETIME WARRANTY UNDER WHICH IT WILL REPLACE THE CLOCKSPRING AT NO CHARGE IF IT FAILS. DAIMLERCHRYSLER WILL ALSO REIMBURSE OWNERS WHO HAVE PAID TO HAVE THE CLOCKSPRING REPLACED ON THEIR VEHICLES. THE RECALL BEGAN ON OCTOBER 12, 2004. OWNERS SHOULD CONTACT DAIMLERCHRYSLER AT 1-800-853-1403.
So at this point you should call your Dodge Dealer and make an appointment to have the recall performed on your vehicle.

If the light is on, there's a fault stored in the computer. You have to get the trouble code to know what's going on. No way to guess your way out of this. Read this post on airbag lights

In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to follow factory Airbag disarming protocol can result in an unexpected Airbag deployment and possible serious personnel injury or death.

i dont know of any state that fails a vehicle for an airbag light but it would be wise to get the system checked out. it means there is a problem with the airbag system and itis possible it will not deploy during an accident or it may deploy without warning. the most likely cause would be a bad clockspring

Te airbag warning is on to alert u to the fact that there is a problem in the airbag system and that it is disabled, it will not turn off until the problem is fixed and the in some cases the diagnostic module reset. The most common cause of airbag warning lites is the rotoating contact under the steering, it has an open circuit.
