Passenger airbag turning off

Here's the situation. When my wife sits in the passengers seat, the "Passenger air bag off" light comes on half the time. It will turn off half of the time (meaning the air bag is on) but the other half of the time the light is on. It turns right off when I sit in the passengers side and stays off, the problem is only when she sits there.

I've had the recall fix on the passengers side seat done already, (before, the light was always on). I don't think it's her size either, she's 5'8" so it's not like she's too small. She's tried sitting in different positions, but we can't figure out what's doing it.

Any ideas? Anyone know what's wrong? Thanks.

I have this issue as well. My wife is ~125 pounds (not sure; it's hard getting a straight answer from her). I thought the passenger air bag was supposed to "lock in" its setting after 30 seconds (per what the manual says), but that doesn't seem to happen. Today, I started the car without her in it, ran it for a minute (the light was on that whole time). Then she got in, and the light went off briefly, but came back on again. Other times, she's in the car when it's started, but the light stays on. Or not.

My car has ~56,000 miles and the warranty ends soon for me, but I haven't bothered bringing it in because I figured I'd be stonewalled.

I've been told my car has no outstanding recalls on it. So, my take is there's no fix and we're SOL.

Negative ---> send me your VIN, let me look at past claims..

In most respects, it comes down to actual occupant torso weight/butt print.. legs dont count toward weight, as they is what we we call in chassis school "unsprung weight"

We were sending the seat cushion back for re-program to change detection parameters or what ever with the pad/module logic.. mostly done on case by case basis.. aisle fella was supposed to go throughw tih customer to evaluate before seat cushion removal.. Occupant Classification System is what it is,, then it inputs to SRSCM the occupant description for PAB discharge.. she as you state may not have enough torso weight or butt print to make system logic respond.

May scan also and verify there is no 1448 code present, and I cant remember if there is a weight calibration or not for the seat, I know WCS we can "ZERO" the seat, dont remember for OCS

Not too long ago, I bought 4-5 lb. bags of rice and placed them in the front seat. Throughout the short ride back home, the Passenger Airbag Off light continuously flashed on and off as the bags of rice shifted around in the seat. I was surprised that such a light load would trigger Passenger Airbag. I figured that one or more of the bags was directly over the sensor(s) and creating just enough force to sporadically close the pressure switch.

rhdins: Check this out. I am printing it out and bringing it to my dealer to have this evaluated and hopefully have the OCS (occupant classification system) reprogrammed so that my wife is correctly "classified" by this thing. (I know that printing it out is not necessary; you can simply mention it to them as "campaign 083".) Advice is to bring the person experiencing the issue, which means I have to bring my wife. I think you should do the same.

Many thanks to sbr711.

Hmmpf. Cover-ups are nothing new to the auto industry. Tonight I hate the whole human race. I'll spend a couple hours of my time this weekend trying to get this squared away. From what I understand, they'll have to ship the seat bottom off to the idiots at the warranty center or whatever it is. Great. I'll plan on driving with one front seat for the next three months.

I do have aftermarket seat covers installed. Do you, rhdins? Just curious, but I don't think mine have anything to do with this problem. This has been happening for longer than I've had the seat covers.

Present the vehicle to dealer service dept in same condition as day it was delivered to retail purchaser.

They will likely send you on your way if presented with coverings over seats,,, Hyundai has TSB about that also, as the covering will prevent side airbag in the upright from deploy proper.. look at it in similar fashion as I wrap you with duct tape.. you can deploy your arms to protect yourself.

Just called two local dealers... First told me they'd have to evaluate the vehicle to determine if there was a problem. Uh... NO, the campaign/TSB explicitly says reprogramming should be done on customer request:

Quote:
If the customer indicates that the "PASSENGER AIR BAG OFF" light has been
illuminating and requests that the reprogramming be conducted, the campaign
should be performed.
This seems pretty unambiguous to me. This dealership could not even find the campaign or TSB, for whatever reason.

Second dealer is saying they need to evaluate this as well, and if there's no OBD codes, it will be done at my own expense. Only problem is that OBD codes have nothing to do with the core problem here.

Apparently I'm the only one who can read.

Contacting Hyundai directly...

Opened a case with Hyundai. Despite many attempts, could not get even the Hyundai rep to understand (or perhaps "agree" is the better word) that this campaign must be performed AT CUSTOMER REQUEST. I kept hearing that the dealership would have to duplicate the problem first. The rep kept telling me the dealership would have to test with my wife or someone her size. That's ridiculous, absolutely ridiculous! From the TSB directly:

Quote:
On AN INDIVIDUAL CUSTOMER BASIS, this OCS reprogramming procedure must be performed if the "PASSENGER AIR BAG OFF" indicator light remains on when small stature adults are seated in the right front passenger position or if the customer has requested that it be performed.
See that word -->OR<-- ? That's a whole lot different than the word "AND".

I'm sure the reason they worded it this way is because (1) This is a serious safety issue; and (2) It's not always easy or even possible to duplicate this issue.

Is it me? Am I nuts? Or is this just stonewalling? Is is possible to interpret this as REQUIRING that a dealership duplicate the problem?
