Disconnect the "hot" wire on your battery for about an hour, or two, and the computer should reset itself and go to the proper settings, recognizing your new equipment.
if the light is on the airbags are off-line (not working)
Its a warning showing the airbags are at risk of deploying. The light is on because the computer has detected a malfunction.
The best choice is to REPLACE the airbags!The SRS airbag is a safety device which can save your life in case of an accident!
The airbag light indicates that the system has detected a fault with the airbag system. You'll need to take the vehicle to an authorized repair facility and have the airbag system diagnosed. I highly recommend that you NOT attempt this work yourself. Airbags are extremely sensitive, and even a small static discharge can cause release of the airbag. Airbags are expensive and untimely discharges are potentially dangerous.
i installed a radio w/ harness and the airbag light is on, how do i turn it off or reset it?
You will not pass inspection in NJ with an airbag light ON. If you owned the car when the light came ON and your airbags have not previously deployed, this could be a sensor or wiring problem. If you need new Airbags, the repair could be as much as $1000. Most mechanics will charge 1 hour labor for diagnostics.
To reset the airbag warning light on a Volvo V40, you must take the vehicle to the dealer. The dealer will check the airbags and turn off the light using a specific tool.
It means you should probably check your airbags
It means the small computer that runs the airbag system has detected a problem with the airbag sensors and firing circuits. So your airbags will not work in an accident. Get it checked.
replace airbag sensors, or fix the damage around them (front end damage i would assume)
Check the plug to your airbags, it may be loose or poorly connected. This light is an indicator that there is a problem with your airbag system.
Problem with the SRS. Take it to a dealer for repair. the airbags may or may not be working.
