Malfunctioning Idiot (Seatbelt) Chime
 
This afternoon, for no obvious reason, the passenger seatbelt chime has started to malfunction. Its worked perfectly for the last 6 weeks since i bought the car, but today it insists that the non-existant passenger should be wearing their seatbelt. Its a little illogical on the car's part: it knows not to turn the airbag on, because there is no weight on the seat, but is determined to get that passenger seatbelt buckled!

I disabled the chime using the methods described in another forum, so its not going to drive me crazy, but it always concerns me when part of a new car doesn't work. It just doesn't bode well.

I checked all of the connections under the seat, where there is a very elaborate Denso-designed system all running to the "Occupant Control Module". Very sinister sounding, no? But every seems to be plugged in where it should be.

Just wondering if anyone else has has a similar problem.

Thanks.

Really, this sounds very bizarre as we here in Oz dont get the passenger belt chime at all. Believe you me, ONE IS Enough.
Adam.

If you are really concerned, get it back to the dealer and let it be their problem. All the best.

The occupant sensing system in the passenger seat must need recalibrated. It will flash the seatbelt light when *ANY* weight is detected in the seat. If the weight is above the threshold necessary, then the "Airbag ON" light illuminates.

I suppose that makes sense, eamiller. Next oil change I'll complain about it.

I hadn't realized when I bought the car that there were six tiny Japanese engineers under the passenger side seat. Subaru thinks of everything!

Thanks all.

When I first got my Outback, when I would take a corner really fast, I would hear the same warning chime. It was funny, I thought I had some sort of sensor telling me to slow down! Then I realized it was the seatbelt chime. I did some searching and found something about 'resetting' the passenger seat by sliding it all the way back and then forward. I did this and since then haven't heard any chiming around curves... anyway, all very strange.

Just rip the chime out altogether, Easy FIX.

I'm having this same problem too, I have too buckle the passenger side seat belt to keep it from driving me crazy! But i'm gonna try the reset method that boris stated above. If that doesn't work to the dealership it goes.

The weight threshold is 79.1 lbs. You might *think* there isnt a passenger with you:)

Probably a defective seat harness/sensor. We had one come off the transport with the exact same problem you're having. There's like 8 sensors under there, so there's plenty of things that can go wrong.

Well the reset didn't work so I guess I'll have to take it in next week to have them check it out.

Fuji_Heavy 01-11-2005 02:37 PM

Took it in and they reset the system, took about 20 min.

when i got my legacy the salesperson told me that that the airbag would be turned off if the passanger weights less than 85lbs.

I have had two strange things happen.
Putting my roller briefcase into the passenger seat causes the chime, seems simple, I move the bag to the floor. I think it weighs about 25 lbs.

The real strange one was when I started my car, moved it in the driveway, letting it run while warming up. Then my sister drove the car, and the chime went on for 20 minutes. She was not happy. I think it may have detected my weight, then hers. I don't get it. Maybe her purse was on the passenger seat, I dunno.

Mercedes-Benz has the same problem a lot.. the common fix is recalibrating the seat with a special tool that designates a human being (three weights that total up to 130lbs?).. if the recal doesn't work, then the weight sensing control module has to be replaced. But that's mercedes.. i don't know if subaru is as stupid as german engineering

impostor 12-24-2005 10:40 PM

Subaru is aware of the issue and has a "fix" for it. They've determined its a defective hinge spring for the seatback recliner handle. Theres a repair kit which has a new spring, hinge cover, and clips. I dont understand how they've determined that the spring is the culprit, but im no engineer.
