Ok, I've done the 'hack' from FocusHacks on previous Focus's and friends, and it works great. I've attempted in multiple times on my current ZX3 and it just wont shut off! I see the light blink 12 times, meaning its off, but it isnt. So i try it again, and it blinks 12 times, pauses, then does it 12 more times to signal that it has been turned back ON. So I've turned it OFF and ON, again, and again. Neither time will it silence the noise, and its [censored] pissing me off!!!!!!!

What else can I do? Cut a wire?

How about just always wear your seatbelt?
And I wouldn't unplug anything from under the seat either. There is a sensor in the seat to tell the SRS that there is an occupant in the seat (sometimes, even multi stage deployment, depending on the weight)
You might not have an airbag deploy for you if you get into an accident...
Then again, if your not wearing your seatbelt, you REALLY don't want the airbag going off.
And if your not wearing your belt, and the airbag deploys in a head-on, it'll probably mean certain death anyways...

I just reached under the seat and unpluged it

Have fun flying through the windshield there buddy.

The seatbelt plug under your seat functions in both tensioning and airbag deployment. In the event of a crash your ass is going right into the steering wheel or even the window.

Unless you feel like becoming another Darwin Award winner, I'd plug that back in. If not, well I won't feel sorry for you.

Dayyum. This seat replacement/airbag light thing becomes increasingly complicated every time I open a related thread!

I'm not looking at it right now, but that connector has about 6 different plugs. One is for a sensor that detects the driver (and I'd guess determines weight for airbag deployment velocity purposes). Another is related to the seat belt being engaged. I've read here that another detects the airbag. I suspect the tensioning sensing is down in the seat-belt retractor. It provides tension when jerked. Or is it more complicated than that? I'm just speculating. Does it only tension when someone is sensed in the seat?

Any experts out there know for sure what all is going on with that multi-plug connector under the seat? In my case it's in an SVT.

Should I be asking this question in a different forum. I could ask my SVT dealer I guess.

Thanks!

If ours is like most cars. The spool the seatbelt winds onto has gears on both sides. Under the side gears in a plate that connects under the spool and has a weight pendulum attached. When you jerk the belt, the intertia from the pull causes the gears to catch the plate as it is swung forward. The plate locks into the gears and stays put. Or when you slam on your brakes the weight intertia keeps going swinging the plate and catching the gears, then locking the belt in place.

This makes sense to me. My car is in this shop right now, but we tested the tensioning by tugging on the belt and it locked as expected despite the seat being removed and the connector completely disconnected.

So, I take it that the following is a misrepresentation of the situation:

...The seatbelt plug under your seat functions in both tensioning...

Re: Question related to unplugging that seat harness!

The tensioning mechanism is completely mechanical. But do we have pre-tensioners in our cars??
Also, I have side airbags in the sides of my front seats...pulling the plug under there will certainly cause these to stop functioning as well.
Here is what you do...get in your car...do up your belt...THEN start the engine...
No more warning chimes!

The mechanical lock on the seat belt spool that you described is the Inertial Lock (Hence in England at least, they are called Inertia Reel Seat Belts)... the Focus also has a Pre-Tensioner system. In a collision, if the crash sensors detect a frontal impact within (I think) 30 degrees of head-on, it fires small charges (or releases a tensioned spring, can't remember which!!) in the cylinders on the inside (i.e. E-Brake side) of each seat rail, which will yank the buckle part down a few inches and so keep you in place firmer and quicker than just via the mechanical means, which will take a few milliseconds to react to the inertial change. Unplugging the pre-tensioner system will mean in an impact you will be further forward than the Airbag system expects you to be, and you will receive a greater force from the deploying airbag than intended (Assuming the Airbags are still operative with the pretensioner system disabled).

As for whoever it was saying they'd rather not hit the airbag if they weren't wearing a belt (WuNgUn I think?): Later Focus have a dual-stage firing system for the Airbag inflation, intended to take into account severity of the crash, speed, and occupant weight. They are intended to cushion you and prevent you from exiting via the windshield, and not just blow your head off like some of the early US Airbags could do to small women etc.

In Europe, the Airbags are smaller in size, but that is due to the fact that Seatbelt use is much higher there than here, and so the Airbags are merely supplemental to the Seatbelt restraint system, and protect your face from injury due to impact on the wheel/dash etc. The US Airbags have to take into account people who don't wear seatbelts, and so are larger, to hold the occupants in place better.

There is a Ford tool you can install on the Pre-Tensioner system when working on or around it and/or the seat, which temporarily prevents it from operating.

Re: Question related to unplugging that seat harness!

Ok, I always wear my seatbelt as well. The reason I want to disable the chime is because sometimes I sit in my car with it running to organize my stuff or to figure out where I need to go next, etc etc. Whatever it may be, I want my AC/Heat on w/ tunes if I'm not on the phone and I don't want to be restrained by my seatbelt, and if the car is on and the belt not buckled, it chimes every 30 seconds and is really annoying. So what can I do?

Thanks

Re: Question related to unplugging that seat harness!

I always wear my seatbelt. Always.

However, say that a freind and I or myself are working on my car, adding something or what not we turn on the car, its in the driveway hood open, doors open we might be looking in the fuse box or something, that damn sounds annoying we end up shoving pens in the door.

Then, when we close the door, the pens die because we forget to take them out and they break lol. So which is it? Would you rather me disable that annoying sound or more pens have to die? I don't need a reminder to put my seatbelt on since I always do it.

You are describing the "Keys are in the Ignition and you've opened the door" chime, not the "Seat Belt not worn" chime, if it is silenced by closing the door switch

There is something quirky with your car if you can't disable the Seatbelt Minder system (but I guess you know that already!

)

How about taking it on a quick trip to a Dealer and telling them about it? If the Dash lamp is flashing correctly, to inform you it's activated/deactivated, yet is still chiming... sounds like a fault.

Sorry I can't come up with a "real" answer for you

Hmm lol, yeah I posted that and realized wow thats not the seatbelt chime. :

Anyways yeah, dumb post for me.
