Passenger airbag light

Hey guys.... My passenger airbag light now stays on all the time unless someone is sitting in it, then the light goes off.... It just started doing it this morning.... Anyone have some insight?

Are you sure it just started? My passenger airbag light is on all the time (telling me the airbag is off) unless someone sits in it that weighs enough to activate the airbag.

after reading this thread, I had to check my 2012 Sport.... maybe cause it's a base Sport, no passenger airbag light illuminated.

Nah... It just started doing this.... That light should only come on if nobody is sitting in the seat but an object is on the seat....

For example, if I set my tools or some books on the empty passenger seat, the passenger airbag off light should illuminate.... When nothing at all is on that seat, or someone is sitting in it, it should stay off....

Now it only goes off when someone sits in it.... It stays on at all other times, even with no objects on the seat....

my dog used to set that thing off and on on my JK. depending on how he is sitting there. I think he does it to bug me at times. wont happen anymore since i converted the Jeep to racing seats and 5 point. I wont wheel in a jeep with airbags. Dentist and bone doctors are very expensive. 1st time those things go off when they should not, people will believe like a holly roller church. Like hitting a IED, BOOM.

I had this issue last summer. Just unplug the connector wait 60secs and plug it back in. It fixed it for me hopefully it's just another loose connection.

Took the words out of my mouth, sort of. The sensor in the seat is not all that sophisticated. They sometimes need to be "re-calibrated". Don't know if that is the right word... but basically by unplugging it and then reconnecting it will many times reset it to a base line. If repeated resets don't work see if your dealer will scan the system for you. Since it is part of the SRS system, the dealer's computer system is able to check all the sensors within the system.

Read through this thread again and had to go out to the Lib and check it out. I stand corrected... I usually have my work bag in my passenger seat and, since it doesn't weigh enough to turn the airbag on, I just assumed that the light was always on but it's not. That doesn't make sense to me though. If the seat is empty the airbag will still deploy in a collision - common sense says to me that and empty/too little weight (in the) seat shouldn't cause the airbag to deploy. Hmmmm.....

The idea of it all is that if you have loose objects on the seat, are involved in a front impact and the airbag deploys, it will send your objects flying around the car at dangerous speeds right? So it turns the airbag off if it detects loose objects on the seat....(ie. books, tools, animals) the airbag will deploy if the seat is empty or there is someone in it only.... it knows the difference between a persons weight, an objects weight, and empty.

So this plug is right under the passenger seat right? I wonder if disconnecting the negative terminal on the battery will accomplish the same thing. I'll let you know what happens when I get home and try it.
