VXDIAG Techstream Works on 2023 Lexus GX460

VXDIAG VCX NANO Toyota Techstream cable was confirmed working with latest Lexus GX460.

Here comes the latest review of vcx nano user:

"All the negative reviews have one common thing…user error. Anyone using Techstream knows you need an old junk computer that you disable the anti-virus software and keep it off the internet. Software works perfectly, unit arrived with the most recent firmware.

Software V18 works fine. Upgrade the FW before, if needed.

Worked PERFECT on a 2023 GX460, 2022 GX460, 2017 GX460, 2019 GX460 and a 2007 GX470.

MUCH better than the cheap cable that I previously purchased.

This worked right out of the gate and I reprogrammed my TPMS sensors and I turned off the seatbelt warnings.

This one has my seal of approval."

VXDIAG Techstream Cannot Find Toyota Proace 2020?

Problem:

I have a vxdiag vcx nano Toyota connector with latest techstream V18.00.008 on a Windows 10 64bit pc. I've managed to get the program and the connector to communicate with my van (Toyota Proace City 2020). Techstream does not have proace in vehicle list. Tried mini vci no Proace either.

Solution:

Toyota Proace is based on a PSA platform. Toyota Proace is a Peugeot Expert and Citroen Jumpy. PSA made Proace for Toyota.

For ProAce project TME has decided the adoption of PSA technical documentation and diagnostic tester.

So you will need diagbox to diagnose.

Techstream is for all Toyota and Lexus except Supra and ProAce. Supra needs Toyota ISTA and Proace requires diagbox.

VXDIAG Techstream Register Lexus LS460/ LS600 TPMS

Most cheap USB OBD2 VCI J2534 cables can only read data but can't write data into the ECU. You need a good quality OBD2 VCI connector for Techstream to register the TPMS sensors in the ECU. I bought several cheap USB OBD2 VCI cables but none of them allowed me to register TPMS sensor IDs into ECU (they could read data), until I bought a VXDIAG VCX Nano Toyota cable for approximately $85 (3 years ago). The VCX Nano cable/connector allowed me to use Techstream to write TPMS ID's into ECU. BTW, if you can, use Techstream 15 or newer version, which allows you to enter TPMS sensor ID's all at once on one screen. With earlier versions of Techstream, you need to enter the TPMS ID one at a time/screen within a short allowable time, or it will time out and you'll have to do it all over again. For registering TPMS sensor ID's, Techstream version 15 and above is a big improvement. I'm using Techstream version 17.

Here is an DIY tutorial on replacing and programming TPMS Sensors – 2007-2009 LS460/LS600 with VXDIAG techstream cable.

Symptom of a bad TPMS sensor: After the engine is started, the tire icon on the dash flashes for three seconds and then stays on solid with the message: "Check Tire Pressure System. Have your vehicle checked by a dealer", as shown in the photo below:

Verifying the bad TPMS sensor with Techstream: Connect Techstream to the car, double-click the "Tire Pressure Monitor" button, and then click the "Trouble Codes" button. It shows Code 2125 with the description "Transmitter ID 5 not received", indicating that TPMS sensor ID5 is not working. Double-click the "Data List" on the left-side of Techstream panel, and TPMS senor ID5 shows only 0.4 PSI, indicating a bad sensor. Screenshots of Techstream are attached below:

Identifying the bad TMPS sensor: While still on Techstream "Data List" screen, pump up each tire to 40 PSI. Techstream shows the rise of each tire's pressure as it is pumped up. The tire that does not show a rise of the tire pressure is the tire that contains the bad TPMS sensor. In this case, it is the front driver-side tire.

Choices of replacement TPMS sensors: I am amazed at the long lifespan of TPMS sensors on my LS460. The bad sensor has faithfully been working for 13.5 years on my car, and the remaining 4 original TPMS sensors on my LS460 are still working. For replacement TPMS sensors, there are basically three choices: (1) genuine Lexus/Toyota sensors from Lexus/Toyota dealers, (2) Denso OEM sensors, and (3) no-name replacement sensors on eBay/Amazon. The part number for 2007-2009 LS460/600 TPMS sensors is 42607-33022. At the time of this writing (May 2021), my local Lexus dealer's online website shows $71.47 per TMPS sensor for my LS460, and my local Toyota dealer's website shows $65.92 for the same TPMS sensor. The part number of Denso's OEM TPMS sensors is 550-0103 and RockAuto carries them at $31.79 each. No-name TPMS sensors on eBay/Amazon carry the part numbers of PMV-107J or 42607-33021 and their price runs anywhere from $7 to $15 each. Given the significant difference in prices among the three sourcing options, I decided to gamble a little bit and went with a seller of no-name TPMS sensors on eBay, who had very high ratings and received a lot of positive feedback. The seller guarantees the battery life of his TPMS sensors to be at least five years. This eBay seller's TPMS sensors for LS460/600 have an almost identical look of the original Lexus/Toyota TPMS sensors. I bought a set of 4 TPMS sensors from this eBay seller for $45, including sale tax and shipping. Below is a photo of the new no-name TPMS sensor on the left and the Lexus original TPMS sensor on the right:

Breaking the tire bead and replacing the bad TPMS senor: I used my LS460's jack against the rear towing frame structure of my GX460 SUV to break the tire bead. It worked effortlessly and perfectly. With the open tire bead, I replaced the bad TPMS sensor with a new one in a few seconds and torqued the sensor stem to 4nm. See the photo below:

Registering (programming/relearning) the new TPMS sensor in the tire ECU: Inside Techstream's "Tire Pressure Monitor" screen, double-click the "Utility" button on the left-side panel, and then double-click the "ID Registration" button. Then, follow Techstream screens to complete the registration (programming/relearning) of the new TPMS senor in the tire ECU database, as shown below:

Clearing the trouble code and verifying that the new TPMS sensor is working: Inside Techstream's "Tire Pressure Monitor" screen, double-click the "Trouble Codes" button on the left-side panel and then clear Code C2125. Double-click "Data List" button on the left-side panel to verify that the new TMPS sensor (ID5 54D6465) has been registered (programmed/relearned) and is showing the correct tire pressure (i.e., 33.7 PSI in my case). Please see the illustrating photos below. Turn off the engine ignition and disconnect Techstream from the car. The replacement of the bad TPMS sensor has been completed.

Hope it helps.

Program 2020 Tacoma TPMS by VXDIAG Techstream

Which is a better Techstream cable to register/program TPMS IDs on a 2020 Toyota Tacoma? Here's the user unbiased review.

Background:

I recently installed a 3″ lift, and naturally, got bigger tires (285/70/17) and new wheels. After a month long, painstaking experience with my local 4WP shop, I opted to not let them work on my truck and decided to do everything myself (minus the alignment and tire mount/balance).

One of the many problems I had with 4WP, including waiting 4 days for my tires to be mounted and balanced, was that I had asked them to scan the new TPMS sensors that they installed so I could program the ECU w/techstream. I was told that's not how the TPMS (system) works and that "the truck will learn the TPMS sensor IDs itself". As a former diesel mechanic, I knew this to be bullshit, despite my very limited interaction w/the TPMS. This issue is what would be solely responsible for the rabbit hole that I would be diving down…that and my spitefulness.

So. Now begins the fun.

I found the model of the TPMS sensors that 4WP installed (Oro-Tek PDQ) and purchased a scanner/programmer that was compatible w/them (ATEQ VT37). Now, this part isn't technically needed if you were able to obtain the sensor ID's from the physical sensor itself or by asking a COMPETENT tire shop to write them down for you when they mount/balance.
I then, like many others, purchased a Mini-VCI cable. It's just a cable right? Ha. No.

So I install the drivers for the cable and select the appropriate VIM on techsteam. I then connect to my truck via techstream and noticed that the vehicle information doesn't auto-populate like on the Mac/Volvo/Hino/Mitsu software I've used in the past. So, I manually inputted it, not thinking much of it.

I then go into the Tire Pressure Monitoring System and open the Utility to program the new TPMS sensor IDs input the IDs which I scanned off the sensors…and get this error:

At this point, I tried changing and reverting other settings from within techstream. They all worked fine. I then tried 3-4 other releases of techstream. Still won't work. After a crap ton of searching I saw the TSB about jumping pins on the OBDII plug, but noticed that one of the spots didn't even have a pin in it, so that was useless. I saw a few "your cable is bad" comments and several "I tried multiple of the same Mini-VCI cables" responses.

I then found someone who had posted something about a "VXDIAG VCX Nano Toyota cable" claiming that it worked for them. I then found a VCX Nano for Toyota (it appears each manufacturer has it's own model) on vxdiagshop.com for $95. I figured if this is what it costs to have something that actually works then I'll try it.

It arrived today and I once again found myself installing drivers and setting the VIM to what I now see as "Toyota J2534". This is beginning to look promising. I launch techstream and connect the truck and the first thing I notice is that it has auto-populated my VIN, model code, and vehicle spec. It also loaded much faster than the Mini-VCI cable.

Jump over to the TPMS menu again, try changing the sensor IDs and…

Well hot dang…it actually worked. Proof below if you need more convincing to spend the money on a better cable:

As you can see, using a very scientific numbering scheme for my new sensors, it worked.

Morale of the story. I spent way too much time and money, purely out of spite for my local 4WP shop and for the future of tire changing freedom. But I hope that this post will help someone else who is struggling to figure out why they cannot program their TPMS sensor IDs with techstream.

Total cost:

$95 for the VCX Nano
$153.67 for the VT37
$32.99 for the Mini-VCI cable

So yea, less than $300 purely out of spite/anger. But I'm also slowly gathering everything I need to do my own tire installs and alignments. And like I said, you don't necessarily NEED the TPMS programmer/scanner. The important thing in that list is the VCX Nano Techstream cable. Without it, you will not be able to program the TPMS ECU (at least w/3rd gens). Don't waste your money on the Mini-VCI. There are other brands out there as well, but from my research, they were far more expensive. The other option is to buy a $300+ TPMS programmer/scanner that comes with an OBDII cable. Should be able to program everything there.

The link to the VXDiag Drivers/Software has both V16 and V17. Also, I don't recommend installing it on a computer you use everyday. You'll need to disable the windows virus protection or it'll delete files it marks as malware. I use an old lenovo thinkpad that I had bought on eBay 2 years ago for use in my garage.

You can probably get away with a scanner that just reads the IDs, or see if a tire shop can scan them for you real quick and write them down. They're a simple 7 digit hexadecimal code. You'll need to know the sensor brand before you buy a programmer, as not all programmers are compatible with all brands (such as the Autel programmers). However, as just a scanner tool, I believe all scanners can read any sensor. I could be wrong, but they all work off the same frequency (315mhz) so I don't see why not. Also, reprogramming the physical sensors only works on reprogrammable sensors. It will not work on OEM ones. So, you don't necessarily need to drop $150 on the VT37. I bought it because I plan on doing all of my own tire/alignment work in the future because I don't trust most of the shops in my area and the good ones are always backed up.
