<!-- from fixya rte -->2004 aveo airbag light on,how can I fix - 2004 Chevrolet Aveo

If the light is on, a code is stored. PERIOD. If you can read the code, then you're not using a professional grade scan tool. Cheap scan tools only read generic codes and don't read B, U, or C codes. And, you cannot turn off an airbag code. You must fix the problem.

have the code retreived using an airbag hand held scanner this will tell you if a sensor is bad or wiring or the airbag control module is bad.

I have a 2008 Aveo and my airbag light has been on for almost a year. I refuse to pay dealer $80 just to tell me why it's on then have to pay them again to fix it. I heard that the sensors under the pass. seat can come unplugged, so my husband unplugged them and plugged them back in and it still the light is on. This is sooo frustrating....I really just want to reset it...anyone know how??

you can watch this vedio, it teaches you how to reset the airbag light.

You use the SRS (air bag) code or any codes, to refer
to a trouble chart,to follow to diagnose any vehicle
system malfunctions.

2005 Chevy Aveo.The horn button acts as a ground for the horn.The ground goes from the button through the airbag clockspring which is where i lost ground on my Aveo.Most likely need to replace the clockspring or rewire the ground,which is what i did! Hope this helps!

Have a dealer service the airbag system as they have a shelf life and most likely that is causing it to trigger (alot like service lights on newer cars).

Hey,
take a look at www.airbagmodul.com

They're working in Airbag-Simulators and Occupancy Sensor-Simulators.

No it needs to be re-set by a dealer laptop with the right software

check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.
