I went to my dealership today to get my factory radio replaced cause the aux input stopped working..It took them about a month to figure out what to order when I kept telling them what the problem was..They finally replaced the whole radio and when I go to pick up my car the airbag light was on..I take the car back and they tell me there is nothing they can do to bring it back monday..They told me to be careful cause my airbag wouldn't deploy if in an accident cause the light was blinking..After tearing the guy a new one for telling me this a technician decided to look at my car..He cleared the airbag light on my dash by using a computer..On my way home i noticed the passenger airbag light was not on (passenger airbag off light) am not completely sure though..Im pretty sure it used to light up when there was no one in my passenger seat..Now I dont know if they just cleared the airbag light instead of fixing the problem which would be horrible cause they're messing with my life..Any help would be greatly appreciated..

the passenger airbag light is driven by a weight sensor in the seat. the only time it should turn on is when it senses something around the weight of a child seat (or a backpack with some textbooks in it). all other times it should be off (when there's an adult in the seat, AND when there's nothing in the seat.

try putting something in the seat that's not TOO heavy (or just sit in it without putting all your weight on the seat) to verify it still lights up

There was a recall on this as well, what year are you driving? I have an '08 and received a recall notice well over a year ago.

There are a couple of factors that play into the deployment of the passenger airbag . The OCS (occupant classification sensor..a mat with a sensor under the cushion of the passenger seat), the SRS system (seatbelt restraint system ) and the airbag system itself. When you start up the car, the system goes to an 8 sec self check to energize the airbags. During that time, the light for the passenger airbag, located under the 3 center vents lights up then goes off. The OCS uses pressure and weight and takes into consideration if the seatbelt is locked into position to determine whether or not to deploy the airbag in the event of an front end collision.

There's only one way to find out and that's to run into a wall, which I wouldn't advise :chuckle:

In my case, since I installed race seats, once you disconnect any part of the SRS system (denoted by yellow connectors) the system is deactivated thus throwing a a dash light as well as the passenger light under the vents. Since they were able to clear that light, I'm wondering if I can throw my buddy's scanner on the system and clear it as well... :gotme
