    Hey All,

    I was searching the forums this morning looking for a way to get rid of that annoying seatbelt chime when I have 'heavy' items sitting on the passenger seat, and for that annoying beep when unlocking and locking the doors with the key fob. I came across these 2 links:

    http://www.tacomaworld.com/forum/2n...-stop-beeps-when-i-lock-unlock-my-taco-3.html

    http://www.tacomaworld.com/forum/2nd-gen-tacomas/20501-chimes.html

    Does anyone know if they work for 2013MY? I have a DCLB TRDsport and tried for 15 minutes this morning and couldn't get either of them to work. Has anyone gotten it to work on the 2013 or is there a detail that's missing from the steps?

    Those steps don't work on the 2012-13 models. I had the dealer disable the seatbelt chimes.

    How much did they charge you to do that?

    I think you can get a fake buckle to put in the passenger seat belt receiver. There is a post about them on here somewhere. People use them for 4 wheelin when they need to see out a window and such, but don't want to listen to the chiming of the seatbelt reminder.

    It's an option in the techstream software. Takes about 20 seconds.

    Alternatively, you could buy the cable and acquire the software and do it yourself for about 35 bucks.

    Ok everyone, after a while searching I have a legit confirmed working solution to this problem.

    First of all, the owners manual lists the seat belt alarm warning as 'customizable' indicating its possible to be normally turned off. it gives no instruction on how to do so, and presumably the dealer can do it for you. methods from earlier model years don't work.

    i did not discover this solution, someone from a scion board posted these instructions which were originally from a prius. but they are confirmed working on the 2013 taco.

    Step one is buy a elm327 obd reader. mine was about 20 bucks, they are all over amazon. you can also use this in the future with your smartphone if you buy a bluetooth model to do all kinds of cool things.

    2nd, plug it in, power up and get a bluetooth laptop/computer something to talk to it. do a normal bluetooth connect, password is 1234. open up hyperterminal, or putty or any basic terminal program. change the com port to your bluetooth serial (mine was com40 as it told me when my bluetooth connected). Connection set to 9600/N/8/1.

    Then basically just plug in the commands below, and your seatbelt alarm will be permanently off. This is basically what the dealer will do if you bring it in, although they may have some fancy tool to do it from toyota.

    Direct Connect CDT
    >LM327 v1.5
    ?

    >ath1
    OK
    * Turn on all headers so I can see it

    >atl1
    OK
    * Turn on linefeed so I can read it

    >at sp 6
    OK
    * Set the protocol to ISO 15765-4 CAN 11/500

    >at dp
    ISO 15765-4 (CAN 11/500)
    * Display the protocol (make sure it took it)

    >at caf1
    OK
    * Set auto formatting on so I can read it

    >at sh 7c0
    OK
    * Set header to 7c0, that's where I'm going to send the command to

    >21a7
    7C8 03 61 A7 C0
    * me - What's your seat belt setting?
    * Taco - My seat belt setting is set to annoy you, C0.

    >3ba700
    7C8 03 7F 3B 78
    7C8 02 7B A7
    * me - don't annoy me anymore
    * Taco - processing

    >21a7
    7C8 03 61 A7 00
    * me - did you get that?
    * Taco - yeah I turned it off, don't you see the 00?

    Enjoy.
