Disable Lexus GS400 ABS Light by VXDIAG Techstream
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).
VXDIAG VCX NANO 2014 Chevy Volt Review
Here comes the latest vxdiag vcx nano gm scanner review on Windows 10 system.
“I own a 2014 Chevy Volt Plug-In Hybrid and have had a serious problem with it refusing to charge because my battery coolant sensor is dead and it randomly starts thinking the coolant is empty (it’s full to the max).
There are no mechanics that work on Hybrid’s electrical systems in my town and I will have to take it to the big city ASAP. But I need to be able to charge as this vehicle is actually extremely inefficient in gas only mode with no regen braking as normally any excess fuel that is burned that does not propel the car forward (or backwards) is used to charge the battery. If it doesn’t charge that fuel is just burnt as waste.
So I bought the vxdiag vcx nano gm scanner from vxdiagshop.com.
This device was able to clear my false error codes and get me up and running again.
I paid the freight to get the MDS2 with subscriptions for SPS, GDS2 and Tech2Win. After some study, I repaired my Volt quickly, and moved on to my others. No worries.
The software does in fact work with Windows 10 and although it is detected a a virus, it is not it’s just a false positive. You can add exclusions in Windows Security Center for each piece of software to prevent Windows from cleaning it up the second you’re done with it.
You can find everything you need online with 5 minutes of googling. People take some time to learn. This interface is a perfect replica of the OEM. You just need to install the right stuff on it.
This device requires about 6 different pieces of software (latest version) to work and all the versions of each need to be compatible with one another. It’s actually shocking that this thing actually does work!”
How to Solve VXDIAG PSA Diagbox Load SDK DLL Failed?
Problem:
Got the PSA license activated for the VXDIAG VCX SE device. After installing the PSA VCI driver, it didn’t detect the VCX SE unit. The driver reported an error “Diagbox Load SKL DLL failed”.
Any solution?
Solution:
Uninstall and reinstall the PSA VCI Driver management tool.
PSA uses a separate driver.
Run PSA VCI driver and check if device is connected.
Then run Diagbox software on desktop.
Program Lexus LS460 07-09 TPMS with Techstream
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.

Some users reported they set up VIDA 2014D software for vxdiag
vcx se or vcx nano Volvo device.
Using VX Manager when click
'Update License' they get a message "The license is invalid, please update or

Here are the possible solutions:
1. Uninstall Volvo driver in vx manager and install it again.
2. If you still did not resolve that issue just connect your device, open VX manager and click on DIAGNOSTIC and install PASSTHRU (you must enable internet connection), after successfully installation you should see VXdiag in your VIDA!
3. If still not working, delete vx manager, install again, then install Volvo and passthru drivers.
