VXDIAG VCX NANO Techstream Add New Key to 2018 Lexus LX

Have 2018 Lexus LX to program a new credit card key, VXDIAG VCX Nano for Toyota works great as I and others have confirmed, it comes with a hacked copy of techstream. Programs keys, tpms, etc. no problem….

Access to the TIS (online service manual) is required:

To program keys that the Standard subscription won’t work and that the “Professional“ version is required. The cost for a 2 day access to find out isn’t all that much. I’ll likely try to program other things too while I’m at it.

By the way, with a Professional subscription, there’s access to something that sounded interesting when I checked it out last night. Here’s a quote from the same page the table above came from. “ Professional Subscribers receive complimentary access to Identifix Direct-Hit for Toyota “ Sound like some kind of knowledge base where professional mechanic, whatever that means, share repair and troubleshooting info/stories. Not knocking the help great members here share when someone is looking for answers, but methinks this Identifix thing might be helpful.

Windows XP or Windows 7 or Windows 10?

Windows XP or Windows 7 or Windows 10 are all okay.

Windows 10: most preferred. 

Review 1.

I run Techstream on a Microsoft Surface tablet and 64-bit Win 10 operating system.

And to be clear, the TIS referenced length of subscriptions is access to the online factory service manual. It does not come with Techstream or the OBDII to computer cable.

Review 2.

I run it on windows 10 on a bootcamp
partition and in a Parallels virtual machine on a MacBook.

Question: What happens to Techstream Lite once the first year is up? Need to renew every year or do you ”own” it after the initial purchase?

Answer: It has to be renewed. That is the big advantage of the “alternate” method. They seem to have broken the time limit. The advantage of the “official” method is that it is supposed to run faster.

One more caveat not germane to 2021 or earlier Toyota/Lexus products. Toyota says that future models will not run using the existing computer cables – their product up until (?? Date), or the existing aftermarket versions. My sources imply the future version of Techstream cable connection (in the USA) is being outsourced exclusively through Snap-On Tools (Usually means $$$$). Probably something to do with the new EV models coming out.

VX Manager ” 60 days left” Solution

VX Manager says that the upgrade was successful (60 days left), Techstream still shows that the subscription is expired.

Solution: Sounds like the patch is not getting installed correctly. Try installing the patch with antivirus off. Then open the patch executable file also w antivirus off.
The patch hacks the techstream to have no expiration.

Finally!

I was fortunate that the original installation went very smoothly, based on what I was able to find online. Not everything online was helpful, however, and “solutions“ to “expired“ s/w didn’t take into account my situation, namely how this is supposed to work (how to start Techstream).

I finally realized that I need to run Toyota Launcher instead of simply starting Techstream.

So….success!

Program Toyota TPMS with VXDIAG or Mini VCI

I picked up one VXDIAG VCX NANO for TOYOTA and paired it with Techstream and easily programmed the new TPMS codes.

https://www.vxdiagshop.com/wholesale/vxdiag-vcx-nano-for-toyota-wifi-version.html

Many of the cheap Chinese cables won’t work for TPMS programming.

Mini VCI cable: program the new TPMS codes NO

I learned that it is the Mini VCI cable (2.0.4) that I am using that has a bug and cannot complete this process of writing new TPMS sensor IDs for a 2015 Land Cruiser.

I have a 2011 LX570, I am replacing the wheels (20″) with wheels from a 2008 LC200 (18″). I have a Techstream (s/w and cable) and I have read and have the TPMS ID’s from the new wheels (and the old). When I go to “register IDs” within Techstream, I get the add wizard, I am able to go through adding the 5 ID numbers (reusing the spare) but when it goes to update the ID’s I am getting the error message below. I have also included the DataList for reference.

I have tried like 10 times with the same result. I have tried restarting the laptop, remove/attache the mini VCI cable, restarted Techstream. Always the same result.

Hope it helps!

Program 2014 Land Cruiser TPMS with VXDIAG VCX NANO

Problem:

TPMS question on 2014 LC.

I leave my winter tires on my stock wheels with stock TPMS sensors. I purchased the Carista reader and pulled the stock TPMS codes, all 7 digit codes.

I bought a set of Tundra Wheels that came with new TPMS sensors and had my AT tires mounted and had the foresight to right down the codes. However they are all 8 digit codes.  I was hoping Tech Stream or another program could get the 8 digit code entered.

Am I out of luck with getting an 8 digit TPMS sensor programmed to my LC?

Worst case, I will pull the tires, pop a bead and install new TPMS sensors but was hoping to avoid that.

Answer to ” I bought a set of Tundra Wheels that came with new TPMS sensors…”

Tundra uses different TPMS sensors, so they won’t work. I believe they are 325hertz vs 315. You can get programmable ones to “clone” the stock ones you have, or buy another set of 200 compatible sensors and program those.

I had some of the same issues and ended up going to Discount Tire where I have purchased tires for years. They were able to knock it out in 5 mins, after I tried for hours on Carista. they had an extra digit. I don’t think they were the same ones you have but not sure what the difference would have been.

These are the ones I bought:

Toyota TPMS Sensor Replaces OE # 42607-33011 315 mhz

One more question: Is Mini VCI the current best link to purchase TechStream? any replacement?

I’ve used Mini VCI J2534 OBD2 scanner for Toyota /Lexus and other automotive software for years on MacBook pros in a virtual machine running windows (or in bootcamp). I had a cheap version of the cable for a while but it didn’t let me do things like change TPMS sensor values. I have a VXDiag cable now and it works great.

This one is what I have.

I also have a mini vci cable, but found it limited in what I could do. I haven’t used it once since I got the VXDiag vcx nano version. I had purchased it directly from the VXDIAG website last year because it wasn’t available on Amazon at the time.

I purchased the VXDIAG VCX Nano with Techstream V15.00.026 for $70. It works great. I had a spare copy & license of Windows 7 laying around that I wasn’t using, so I installed it on a virtual machine (using Virtual Box). It all worked without a hiccup. Going through screens in Techstream is pretty quick, too, especially compared to what people describe in all the other threads that use the older non-Nano cables.

After I got it all set up, I noticed that VXDIAG also offers a VMWare Player image, but I haven’t tried it out.

Here are some applicable links from their website that were helpful, but weren’t obvious at first:

VMWare Player image, and
VX Manager download (the driver that allows the USB device to be identified and work):

Installation instructions:

The USB-only version (this is what I got):

https://www.vxdiagshop.com/wholesale/vxdiag-vcx-nano-for-toyota-compatible-with-sae-j2534.html

They also have a VXDIAG Nano Toyota WIFI version, but that seems like security problem in my opinion, making my laptop connect to the device WIFI. You can find it on their website if you’re interested in it.

Hope it helps!

VXDIAG VCX NANO test on Land Cruiser LX200

I believe Toyota Techstream software can see what all the sensors are reading.  I need to troubleshoot a seat heater malfunction on my Land Cruiser LX200.

Alright, Techstream cable arrived.  I’d get the newer VXDiag VCX Nano Toyota cable. You can buy it from their website (vxdiagshop.com) if that feels safer. The reports are that it’s much faster and can do more things within TechStream. They send a newer version of Techstream, not that the newer version will buy you anything. I suggest trying this one because using Techstream with the J2534 adapter takes quite a bit of patience.

I was able to diagnose a seat heater malfunction to a faulty sensor. It turned out the sensor had been unplugged by the previous owner/dealer in the seat. Techstream was able to tell me specifically that the temp sensor in the driver’s seat was malfunctioning.

I have been able to program Key fobs and diagnose systems with it for everything I’ve needed so far.

For anyone looking to buy, I highly recommend the vxdiag cable instead. Those cheap Chinese mini vci cables are fine for some functions, but won’t do others (tire sensor reprogram, etc.).
