This is most probably one of two problems, if the light goes on and off whilst turning the steering wheel, it is most probably is the slip rimg which sends the neccesary signals to the steering wheel components. it could possibly have a break in it causing eratic contact.

However, these cars are known to give problems with the passanger and driver seat occupation sensors. these are pads within the seat that detects whether someone is sitting there in order to know which airbags to deplyoy in the event it would be neccesary.

The only way to determine wich component is faulty the vehicle will have to be tested with diagnostic equipment.

It may be related to a window regulator malfuntion. If your winsdow needs to be or has been replaced they may need to also replace the sensor. It senses when the window is malfuntioning and triggers the airbag light. In the event of a crash the airbags are deployed then the windows are to automatically roll down for easy escape if need be little swanky safety features that BMW has placed in their cars.

On a 2000 3 series once an airbag or sensor triggers a fault the light does not go out until it is reset if the airbag light looks half light up and other electrical problems have been experienced such as with radio i would replace ignition switch elec trical component if not i would bet you have a bat mrs control module

Why would airbag light go on


The airbag system on many cars is supposed to have a "test" feature.
This means the light will come on temporarily every time you start the car, as a "computer-start-up feature".
You would have a problem is it stays on.

Airbag light


Obviously the computer in you car does not sense the airbag. It could be something simple like a bad connection or something major where the propellent or gas generator in the old airbag is faulty. In any event your system will not deploy so you should recheck your wiring and if that doesn't fix the problem, the airbag should be replaced.

2004 jeep liberty limited 4x4 airbag light goes on when you start the car then goes off for a few seconds then comes back on . both dash light and grab handle lights do this


The most probable reason for the code is the battery being dead for a while, there is a capacitor in the airbag circuit to make sure the airbag can go off in a collision even if the battery disconnects itself in the process. There is a slim chance it might be something else but either way the shop should be able to tell you what the problem is, and get it fixed; sometimes, scanner reader could helpfull to know exactly what fault code is stored there. keep in mind that this isnt an OBD codes reader, this is more specific for Airbag Systems.

Also, isnt rare to know that the airbag warning light is indicating the airbag(s) may not be functionig. As it says in the manual, "Ignoring the AIRBAG warning light in your instrument panel could mean you won't have the airbags to protect you, (or your passangers), in a collision...have the airbag system checked right away". Always wear your seatbelt. On 2004 there is a light on the passanger grab bar that indicates the passanger airbag is off. This happens when a child is in the seat to protect the child from the sudden force of an airbag. It can also be fooled by a package or briefcase on the seat. This is normal. When an adult sits on the passanger side the light should go off. This information was an addition to the 2004 manual.

Check THIS ARTICLE for additional details.

Hope this helps.

My airbag light blinks 7 times when i startmy car


{: ) If the airbag light goes off after that 7 blinks (some are 6 or 8), that will be normal. The airbag module will blink the airbag warning light on the cluster while performing self-test during initial start-ups. After the self-test and the airbag module did not detect any fault within the airbag system, it will turn the warning light off. If the airbag warning light continuously blink or stayed lit after the expected elapse time, then there is really a concern and you need to double check the airbag system with a scan tool.

What does it mean when the airbag light comes on?


Either the sensor in the bumper has lost communication with the airbag module, or the airbag module is bad, or the airbag package itself is damaged somehow.

Airbag light goes off when passanger seat in use, & on when not


even with exchanging the sensor the calibration could be off. without pulling codes from the airbag system it would be hard to guess for sure but id say you need to have the dealership do a recalibration on the seat

Airbag indicator light


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
