VXDIAG VCX NANO, VCX SE, VCX Plus, VCX DoIP multi diagnostic tool software and hardware support from vxdiagshop.com
Problem:
Got the Techstream 18.00.008 software installed and vxdiag vcx nano Toyota interface connected to vehicle, but cannot find 2021 Tacoma (US model) option. Any idea?
Solution:
Techstream since version 15.00.026 does have Tacoma 2021 option.
Select the America region.
Then select the vehicle model.
Problem:
There is a problem with VXDIAG VCX NANO Toyote techstream v18 software and 2015 Toyota Avalon. The VCX will connect withthe vehicle, diagnose and test CAN BUS communication, but
cannot read live data.
Error “Select system is not responding or not available.”
Solution:
Ensure the correct vehicle model manufactured region is selected.
Only by selecting the correct region in the software will the live data be displayed.
Question:
Cannot find Toyota Aygo 2023 in vxdiag vcx nano Toyota techstream 18.00.008 software. Does it support Aygo 2023?
Here is the clue.
Toyota Aygo is based on a PSA platform. Toyota Proace is a Peugeot 106 and Citroen C1. The Toyota Aygo was reincarnated into the Peugeot 106 and Citroen C1. So in common, all these shared mostly the same ECUs so had a better chance of talking to most systems.
So you will need PSA diagbox to diagnose.
Techstream v18 cannot diagnose this model.
Use diagbox or universal scanners, Launch X431 or Autel etc.
How to use Toyota ISTA to diagnose latest Toyota Supra J29 vehicles?
Step 1: Download Toyota ISTA from the official Toyota website. You don’t need to sign up or pay for anything.
Step 2: Install Toyota Techstream and activate it.
Step 3: After activation of Techstream, install ISTA. Toyota’s ISTA checks for an activated Techstream install. Due to that, there is no need for additional activation in ISTA.
That’s all you need. If you want to use the psdzdata from the ISTA install for ESYS, type this command into CMD as administrator:
MKLINK /d “C:\Data\psdzdata” “C:\Program Files (x86)\ISTA4J29\PSdZ\psdzdata”
I was able to successfully do flashing using ESYS 3.30.1. I was unable to test coding as I was using a VM and launcher pro won’t activate in a VM.
NOTE:
If open ISTA J29 and get a window titled: “Toyota ISTA usage notes” and there’s an “X” to close it. But if close it the entire software closes as well.
How to bypass this message screen or how to go to the ISTA menu?
Switched resolution to 1280×1024 and is able to see the agreement acceptance button. That window is gone.
Problem:
Received the vxdiag vcx nano Toyota cable and set up Techstream 18.00.008 software on Win10 laptop. Tried to program a spare smart key on a 2022 Lexus NX350h. Techstream software asks for a pass-code.
Here is the clue.
The newer Toyota’s have an extra security component even adding keys diagnostically will be a problem unless you have the special password.
These rolling code changes every time you plug in. You can buy code online directly or have other tools to bypass the pin code.
Best bet is Techstream subscription with NASTF.
It’s the $65 security professional script. If you have a yearly subscription there is no cost. The yearly subscription costs $1,295.
You can purchase a 2 day subscription at a cost of 65 dollars. Then you have to wait for email ( up to half hours) then you can re-log back in to site and get 1 free key code. It’s much quicker to just pull out the drivers door lock cylinder and get the key code. It’s stamped right on it!
If bypass the seed code, there is no option for all keys lost or generate smart key, only add key, then add the key.
Once you have reset immo, you go back and add key.
Customer question:
It is a 2021 Toyota RAV4 Prime. When choose a vehicle in Techstream V15 software it does not list the Prime as an option. Just the normal Rav4, Rav4 EV and Rav4 HV. Which option should I choose?
Here is the clue.
The early V15 didn’t cover all 2021 vehicles like the Rav4 Prime and the Venza HV, V15.20.021 was the first to include them.
So you need version 15.20.021 and later. Choose either 2021 Rav4 or Rav4 HV.
Also have to choose a proper cable.
User feedback:
I updated Techstream to V15.30.026 and it gives the option of a Rav4 PHV and it works (using the vxdiag vcx nano toyota cable). I was able to address and clear the code and now all is good electronically with the car!
FYI:
Our customers also tested version 18.00.008 and it knows about the 2023 RAV4 Prime. V18 is what people use and works on anything upto 2023.
Here we post the troubleshooting steps below for the ABS Light always on condition as they are in the manual.
You will need a vxdiag vcx nano Toyota cable with Techstream software. You can also rent Techstream for like $10/day from Toyota, after you get the OBDII VCX to USB/WiFi device.
DI-459 (page): ABS Warning Light Circuit
1. LEXUS hand-held tester: Check if the ABS “ON” and “OFF” are shown on the tester. OK: Check and replace ABS & BA & TRAC & VSC ECU. [Techstream will check the ECU’s, and report out their condition]
2. Repair the bulb or combination meter assembly
3. Check ABS solenoid relay: Shows pin-outs and continuity checks
4. Check the ECU connectors are securely connected to ECU
5. Check operation of the ABS warning light (See Step 1) [redundant check]
6. Is DTC output? Yes -> repair circuit indicated by the output code
7. Does ABS warning light go off if short pin is removed?
No: Check for short circuit in harness and connector between warning light and DLC1 and ECU (see page IN-31).
Yes: then proceed to 8
Page IN-31: Several pages describing standard troubleshooting techniques for connectors and ECU’s
8. Check ABS solenoid relay (See step 3). Bad: replace relay
Good: Check for short circuit in harness and connector between warning light and DLC1 and ECU (see page IN-31).
Tutorial: How to replace and program TPMS sensors on 2007-2009 Lexus LS460 or LS600.
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.
*Cheap mini vci cable won’t work TPMS. You will need vxdiag vcx nano Toyota or Mongoose cables.
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 my case, it is the front driver-side tire.
Choices of replacement TPMS sensors:
For replacement TPMS sensors, there are basically three choices:
(1) genuine Lexus/Toyota sensors from Lexus/Toyota dealers,
(2) Denso OEM sensors
(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:
If you have budget, better get original TPMS sensors.
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.
Done.
