Seat belt chime bypass / disable

[dre99gsx]

Those of you who don't know, our seat buckle receptacles use a two wire hall effect switch. Basically, it senses the seat belt blade via magnetism. Once there is interruption in gauss, the sensor either allows current to flow, or doesn't.

If you need to bypass the chime, in effect fooling the system that a seat belt is always plugged in, simply open up your seat connector under your seat (big yellow connector), and pull the seat belt receptacle connector out. It will most likely have a black and red wire on it.

On the yellow connector itself, insert a 274ohm resistor (1/4w is fine). This allows just the right amount of current to flow through the loop. You can probably use 100 ohm, I just had none laying around.

The system pulses voltage to the seat belt at about every 400ms to check that it is plugged in, not plugged in, shorted or open.

Thanks, useful info indeed

Any idea on how to make the car STFU when I have the key on and the door open? You'll be my hero

DIY? :/ that's too much if tech speak for me unfortunately. and i reallly want to get rid of this chime.

I hope this is for your aftermarket seats, and not because you don't like wearing a seatbelt

This works! I used a 320 ohm resistor. I always wear seat belt while driving, dont worry

I would like to disable the beeper for all functions (seat belt, door open, lights, etc.) and keep the warning light. Anyone?

You have to be very careful here and do a little risk management.

The Safety Information Module (SIM) of the Advance Safety Electronics (ASE) system evaluates the severity of each crash into four levels:

CS=Crash Severity
CS 0: no crash (parking damage)
CS 1: light crash
CS 2: crash of medium severity
CS 3: severe crash

For example, in the event of a front-end crash, a distinction is made between crash severity "light to medium collision" (CS 1/CS 2) or "severe collision" (CS 3).
In the case of crash severity from light to medium collision, the driver's/front passenger's airbag are not triggered if it is detected that the occupants are wearing seatbelts.

If the occupants are not wearing seatbelts, the driver's and front passenger's airbag would be triggered.
The seatbelt tensioners are triggered in all cases.

If you do bypass the Hall-Effect sensors and forget to put the belt on and have a mishap above a 'parking damage' (CS 0), then you as the driver will have NO active or passive protection since the air bags will NOT deploy exposing you to potentially bad injuries. If you do this to your passenger seat belt, you really must be diligent.

Now you also have to also evaluate the legal aspects. I don't know the actual data/law, but I would be willing to bet that if you had a mishap and were injured and the insurance company found out you were not wearing a seatbelt, then did some more investigation and then discovered that you had disabled some of the 'airbag interlocks', you may open yourself up to having the insurance company disallow your medical claim. You can take this even further and forget to tell your passenger and this happens, they could sue the crap out of you and you are definitely liable with no insurance backup..

I am not saying not to do this mod, but you have to do some careful thinking on this.

As long as you wear the seat belt, nothing to worry about. Disarming the chime itself may be another option.

AWW YEAH, totally doing this next chance I get... Door chime drives me nuts everyday. Thanks.

I'm with Shipkiller on this. It's just plain nuts to disable this system in anyway. You open yourself to expensive liability/lawsuits. If the chime bothers you that much find out where the chime is located and disable the chime.... Doing that has to be less likely to bite you in the butt....

Thanks for this! The car chimes incessantly any time I put a backpack in the passenger seat. I've been looking for a fix. And no, removing the backpack is not a fix.
