Default 2022 Icon programming cable

I got this figured out. I will post the pieces here.
https://www.amazon.com/dp/B07TS3GPQ1 will do the trick.
It uses the same drivers as the expensive device for older Icons.

I need to provide a diagram for the 4 individual wires coming out the back end of this thing. You will need to make an adapter cable that goes between these 4 wires and a 2X2 molex connector that goes into the cart.

Will post the diagram soon - got to go now.
Editted:
The link above is what I purchased. Looking carefully at the picture, I hope
they didn't change the device - looks like there is an extra pin...
stay tuned.

So it's straight serial comms then, which makes sense. Do you know if it uses 3.3v or 5v logic? Also what baud rate? Thanks for the info.

I would be cautious to claim it will work with older ICONs using the Toyota NEOS software, but I have no clue on the 2022's.

That's great if you've figured out how to make a cable on the cheap for 2022's. Have you obtained the software?

Talk about a TEASER of a post...😄

I doubt it, looks like they use very different wire protocols. The Toyota NEOS uses CAN, while so far it looks like the newer controllers use Serial. Two very different and incompatible technologies.

Sorry I had to run.
Itís new software, will not work with NEOS.
Iím still out, will provide diagram later.
The software has different access levels which are password protected.
By default, it lets you only look at things.

There is a jumper on the device that you set for either 3.3V or 5 - set it for 5V.

Attached are a couple of pictures of the cable I made.
One shows the pinout on the device, one shows the end of the cable, and one
is a hand drawing of which wire goes to which pin - the labels rx,tx,vcc,gnd match the labels on the circuit board on the device.
The 4 pin ribbon cable that is attached to the device comes with it...
This is the same molex connector that is used on the NEOS cable.

If you get a copy of the software I (and others) would love to take a look at it. I'd try decompiling it and seeing if I could reverse engineer anything.

Being that it's serial and potentially some Chinese controller...I suspect it's written in C/C++ and may have some odd assemblies that might be difficult to reverse engineer but I doubt it has any sort of brute force password protection...but maybe?

Great info though!!

Bob does it have to use this FDI adapter or would a standard Serial to rs232 adapter work with a db9 connected with the mating molex connector?

Thanks for the info and updates! My dealer worked pretty hard on mine since it was his first try at a 2022. Had a hard time saving changes and it would keep going back to default. Still waiting for more details, but he is busy.

I will say he did a pretty nice job. First 2 days I just drove on the roads. Got it up to 36mph on the flats. Takes a while, but gets up to 20mph pretty fast. Rides very comfortably at 30mph. I added spacers and GTW Fusion tires, so much more stable. On the golf course though, it is FAST. Takes off really fast, have to really feather the pedal in areas you need to go slow. I am pretty sure I could play a round of golf in 2 hours if no one was ahead of me. Strange feeling going 30mph down the fairway to your ball. Suspension and brakes are so much better than normal golf carts. I tried to do a little power slide one time and the brakes just shut the cart down so fast, no slide. Lol

Looks like we just need software and a bit more understanding of the best way to program this and we will be good to go!

I'm shocked they let you on the course with your own cart. My local course says the fast ones tear them up. Those GTW tires probably make a difference though.

Your experience sounds the same as my 2021. Fastest I hit is 38 and it's scary. Flats I'm cruising 30.

I'm still wondering their reason for the change? Maybe cheaper?

Excited to hear what everyone finds out though.
