Anybody know of a quick (and reversible) way to disable the drivers seat belt buzzer?

Let me clarify. I always wear my seat belt when actually driving anywhere (I feel naked without it).

However, I don't enjoy the buzzer going off when I undo the seat belt to get my wallet out of my pocket at the airport parking garage, or when I use my car to drive super short distances in parking lots, etc at super low speeds.

Suggestions, methods?

Read the above link.

 

I have done that multiple times... did absolutely nothing even though it said "b off" afterward. I will probably pull the piezo at some point

 

that's all wrong go to this website.. it's better for everything...

thats actually the process I used. It gives you the "b-off" indication, but makes no change otherwise on my car.

 

Or you can bring it to a dealer and have them hook up the scanner and turn it off. Not sure how much they charge to do it.

 

Look under the drivers seat from the front floor board. Attatched to the seat underneath you will notice a white molex plug on the right and a smaller 2-pin white molex plug to the left of the bigger one (consol side). This 2-pin plug is the seat belt indicator circuit, simply unplugging it from the snap-in harness used when removing the seat will disable your warning chime and dash indicator. For those that are still unsure, your looking for the plug with a blue and a white/black stripe wires in it. My car is an 07. I imagine wiring is the same for all years though.

 

Disconnecting the seatbelt in use switch and seat position sensor for the drivers seat (by unplugging them) may also prevent the seatbelt pre-tensioner and the Supplemental Restraint System (SRS, airbag) from operating in a crash.

In other words you may be saved from a few moments of being annoyed by the warning when you undo your seatbelt, but in turn, the airbags may not operate when you need them to.

Potentially much safer to learn to live with the minor annoyance of the alarm doing it's job or to just silence the sounder itself.

Your choice...

Seat belt tensioners are a manual operating system built into the seat belt release its self. The seat belts operating properly do not rely on a electrical systemto keep them in order. Hence if you grab your seat belt and jerk it rapidly it locks, same as in a wreck.

Airbag systems are generaly very tempremental (sp?) in that if the seat belt circuit being unplugged affected the airbag system it would pop the air bag light, indicating a problem in turn the computer would turn off the airbags. Unplugging this molex plug does not turn on the airbag light so I would say, but not promise that your safe. There is always a risk involved with disabling safelty system functions. So do so at your own risk always.

No, *sigh* the seatbelt pretensioners are a sensor activated system tied in with the SRS system. They have explosive squibs that fire on sensing an impact and wind the seatbelts tighter...

See: http://tijil.org/Scion_Docs/05_tC_Sh.../141%20SRS.pdf

 

Holding the trip meter switch in for 10 secs, and then buckling the drivers seat belt did indeed disable the buzzer for me (ah...silence is golden).

When I got the "b_off" indicator, I turned the ignition back to off. Then I started the car as normal, and drove and the buzzer didn't come on without the seat belt buckled.

Just curious the number of tC's that this "easter egg" works for. Several people said it didn't work...could this be year model related?

 

That feature could have changed when the tC went to a two-stage airbag system tied into seat position.

 

thanks for bringing this topic up... it made me remeber to get mine turned off again.. ahhh nice and quiet now... Thanks Guys!!

 

I have heard of it not working on the 07 model.
But i do have it done on my 08.

 

It worked on my 08!

 

It worked on my 07

 

I have an '09 and it worked on mine.

The only thing that I have to say about unplugging the seat belt sensor is that I believe that most, if not all, modern cars have the 'black box' and I am assuming that the tC has it also. So if by chance you are the unlucky person that gets their 'black box' pulled after an accident, and the seat belt sensor is unplugged it may record it as unbuckled. I would assume that this would be a question that an insurance company would ask you about.

 

Had no problem doing this, worked on the first attempt

 

why worry about the beep?? just have your belt buckled. you ALWAYS should have it buckled. lolz.

 

This is directly from the introduction of the tC Owner's Manual...



(IIRC, the airbags will not deploy if the seatbelts are not in use.)

Insurance companies and increasingly law enforcement are interested in what the "black box" (Event Data Recorder) has to say about the last 5 seconds of driving...
