Deactivating the seatbelt chime

The seat belt chime in my truck drives me nuts at times, and I have been interested in a reversible, easy DIY way of stopping it.

I had my seats out of the cab to wash my seat covers, so I decided to do some investigation.

To accomplish this task, you must understand how a seat belt chimer knows to chime. Inside the seat belt housing there is a plunger that your belt presses in. It actually pretty simple when you look at it. So how do we make this plunger permanently pressed?

You need to remove your seats to access the seat belt housing


Using a socket, remove the belt attachment housing from the seat.


Using a small screw driver push in the tab to allow the sensor to be removed


You can now slide the sensor out of the large grey housing for the buckle.


Using your small screw driver push in the tabs to remove the sensor cover.


I chose to remove the small circuit board to make sure there was no way to damage it.


Looking at the plunger.....The white part is pushed in by the metal of your buckle. The top left section contains a small magnet that is sensed when in the buckled postion by the circuit board I popped off before.


Here you can see the plunger pressed in all the way. On the non magnet side of the plunger, figure out how far in the plunger slides.


Based off your looking at how far the plunger goes, drill a small hole in the outside of the plunger housing.


Slide a small zip tie through the hole, with the plunger depressed. It will prevent the plunger from moving outward.


Another view...


I didn't get a non blurry pic unfortunately, but using a set of wire dikes, cut off the zip tie where it comes out of the housing on the outside. There is no need to actually put the zip tie through its end and tighten. There is not enough room for this, and you basically made a pin through the hole to keep the plunger back.

Since the zip tie slightly sticks out of the housing I needed to trim a small spot in the side of the housing.


Slide the plunger back into the seat belt housing, and snap the cover back on.


Bolt the seat belt housing back on and reinstall your seats.

My seat belt chimer no longer goes off. Please don't tell me to just wear my seat belt, sometimes people have reasons for not wearing one. For instance I quite often have a gallon water jug on my passenger seat. That is enough weight for the seat to think there is a person and set off the passengers alarm....

 

There are easier ways posted on here that involve just removing the spring. I just disconnected the plug under the seat on my driver side. This does not work on passenger side because it also disables air bag.

 

I just had the dealer disable mine in the cpu at my first service.

 

Any way this mod might affect the air bag system?

 

I wanted it to be without the dealer. That require me to pay them, and I didn't feel like going there.

 

The ways that I saw was have the dealer do it with the computer, or remove the speaker from the dash. I didn't see anything on removing the spring anywhere. My way can be undone with needle nose pliers in a minute.

 

does the trick with the odometer no longer work on those? ive been chime free since 2011... takes like 15 seconds total.

 

As did I. As I understand it if you ever reset, battery change or something like that, the chime would come back. Would be nice if we could get into program from home and change chime.

 

With the odometer? What is that technique?

I realize this is for a 2011 soooo things may have changed. but hey, if it helps one person, im happy lol

 

It does not work with newer trucks.

Now it's either Tech Stream, dealer, or janky modding.

 

well shit. good to know. damn kids and their fancy newer cars.

 

I just yanked the buzzer out. Dont have to listen to beeping when I open the door now either

 

This my favorite fix!

 

2012+ are ecu based as far as controls for seatbelt chime.

the way described above might affect airbag deployment etc. Have the dealer do it or do it yourself.... i can turn mine on or off in about 2 minutes with my laptop

 

do tell...

 

Laptop with techstream cable, and techstream software.

Or you can do it with the proper commands over a bluetooth OBD reader + telnet on a laptop / android phone

 

mine were jerks and refused to do it. I refuse to go back to them for anything

 

guess ill be looking into this now. cool thanks!

 

Doing this makes the truck think the seat is always occupied. How would that effect the air bag? If the truck is driving, I am in the driver seat so its correct....
