Taco Programming
 
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:

Step one: Open the drivers door and insert the key into the ignition

step two: Remove the key from the ignition and, within 5 seconds,
reinsert the key back into the ignition and switch to the on position.

Step three: After 10 seconds, the system enters the answer-back mode

step four: Within 10 of the answer-back beep the switching mode is
started, press the remote twice and teh system will turn off
or on based upon which the system is set.

1) Turn the Car 'ON', but do not start the engine (Leave your foot off the brake). Cycle your trip reset knob until it reads ODO. Turn the ignition back off. Wait a couple of seconds.
2) Make sure seat belt is not fastened
3) Turn the ignition back on, do not start the car (Leave you foot off the break) As soon as you see everything light up, press and hold the trip reset knob and do a long 12 second count.
4) Keep your finger on the trip reset knob. Fasten your seat belt, as soon as you fasten your seat belt, you should see the ODO display go from XXXX miles to "b-on". At that time take your finger off the trip reset knob and press it again. It should cycle to "b-off". You should be all set and turn the ignition off and unfasten your seat belt.
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.

Disabling seat belt alarm 12-13
 
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.
