Tmps
Just picked up a low mileage 2014 GX Ultra Premium (I'm in Canada) from a IS350
My factory rims are currently on winter tires and I will be purchasing a new set of aftermarket rims for my summer tires.
For the TPMS, does the GX recognize two sets of TPMS? I'm hoping it does so that I don't have to get it programmed every time I swap over the wheel set.
Will it recognize aftermarket TMPS (the factory ones are CAD$300 vs CAD$200 for aftermarket)?
Thanks

It does not ...although I recall that early years '10 or '11 in other markets outside of North America may have had the 2nd set capability. They will have to be reprogrammed on each swap.

I was able to have a local tire shop clone my OEM TPMS sensors. It wasn't without effort, but the owner of the tire shop was a good sport and agreed to the "science experiment". The programming device required an update that meant the programmer had to be flashed. We had initial problems with first set of TPMS sensors since the TPMS programmer company had split into two and we required sensors from the other company. In the end, we were able to clone the sensors and it works like a charm. I am now able to swap tires (winter set/summer set) without the need to reprogram the TPMS sensor IDs using Techstream. The only potential downside is the reliability/life of the cloned TPMS sensors. My previous vehicle was a 2006 IS250 and I had bought sensors with winter tires when I purchased the car. Eleven years later (prior to selling the car), all sensors still worked. Time will tell if the cloned sensors will last as long, but overall I am extremely pleased. Would highly recommend!
Thanks,

I believe it was an ITM TPMS sensors. Initially, I was trying to go to a Schrader product without the help of a tire dealer but I had trouble locating a used programming tool in my area. The other alternative is purchase the TPM sensors already programmed but you will need to have the current TPMS IDs read or pulled via Techstream. In the end, I chose a tire dealer that I was willing to deal with versus going out on my own.
In terms of how it is going, I will always clone my second set of tires unless the vehicle supports multiple sets of tires. I have has no problems and a couple months ago, swapped my winter tires for summer tires. I didn't miss having to mess around and reload the TPM sensor IDs. The one drawback is that your spare has TPMS sensor. I have no plans of rotating in the spare tire, so it just lives under my truck. If it was rotated in and you did a tire swap out after, your TPMS sensor id's would not match.
Hope this helps!

Just installed TechStream so I could program a couple of new keys for my rig. (BTY, worked great, 2 key fobs programmed first time, first try.)
So my question is: are there any tips or tricks that TechStream can do for a GX 460?
Maybe fold mirrors when shutting off ignition? Or anything else?
FYI, mine is a 2013 Premium, in case any of the tips or tricks are specific to year or trim level.

I saw this thread wasn't that old and I'm trying to find a techstream so that I can do is zero point calibration after doing the crawl control install. I'm worried about doing the paperclip calibration and not having 10 second of straight road right after I do it. Can you send me a link to where you got working cable and if it has techstream then that's okay otherwise I saw a post with a current version. There's so many options on Amazon and I thought it was weird that the sellers mention needing to remote into my computer to get it to work. That seems like a really easy way for people to gain access to my computer.
I just don't understand the zpc.

I dont think the poster was referring to car windows down. It was more about remote desktop access into your current windows pc to install and work with techstream.

Techstream?
I have spent the past hour looking on here and Ih8mud and can't find the two links I saw. They are to the current and next to last version of techstream that I read in a post. Got the crawl control installed and have to do a zero point calibration and the cable is in the mail 
I don't see them in a sticky either, even the FAQ/mods/etc sticky
Does anyone know what thread that was in? Sorry

I wanted to share some information I learned about TPMS ID’s the other night.
There are two different kinds of TPMS ID’s and most of the handheld readers are able to show both. A few button presses and it converts to either ID.
Toyota and Lexus uses the hexadecimal format for programming.
I had a different set of wheels read at a local shop and snapped pics so I could do the programming. I didn’t realize that they had it in decimal format and was given all numbers. There are online converters that can take a decimal and change it to hexadecimal for you. Once i did that, TPMS programming was no issue.
note: if the converter gives you less than 7 digits in hexadecimal format, just add the number 0 as a placeholder at the beginning of the ID code.
Here is the website I used.

- There is a “decimal” ID which only shows numbers (mostly 9 digits long, sometimes shorter).
- The other is the “hexadecimal” which shows the ID as Letters and Numbers (usually 7 characters long).

Hex vs Dec is just the view. The TPMS ECU always stores in hex, and almost every ECU will use Hex.
I guess if you have a tool that only works in Hex and you get ID's that are in Dec, then you must manually convert it before use. My Autel selects the correct base for the vehicle chosen in the tool.
