Godiag j2534 is an affordable J2534 based passthru interface for various software programs, HDS, ODIS, ELM327, Forscan, Techstream, GDS etc.
Here comes some unbiased reviews of the godiag j2534 cable.
Godiag J2534 or VNCI Mini it’s the same hardware built by ROKWY.
I buy it and made a little review :
FIRST: Use Godiag drivers: it provide a little software that provide firmwares updates, HDS pin Tool and TECHSTREAM keygen (v12 to v17)
THEN: Windows 7 and olders are not supported (recognized as N32G43x Port but no usable drivers).
You need to use Windows 8, 8.1, 10 or 11.
Meanwhile, driver works with Win 11 22h2 you can use third party softs.
Works fine with Scanmaster ELM: reconized as ELM 1.2 device
Works with ODIS 9.1 and Techstream.
Not tested with others software at this time.
The godiag j2534 USB cable is a good length and works like a charm one. The key for me was to plug it in to my car first then hook up to the laptop and then it downloaded and extracted the zip file and worked flawlessly. I was able to read the abs code my crown Vic had for a faulty abs module. Also please be sure to save a file of your OEM settings before making any changes or you’ll regret it if you make a mistake.
I ran Toyota’s Techstream with this godiag j2534 dongle and it worked just fine. Just be careful when downloading files from godiag’s website as I detected malware. For example when I downloaded Techstream archive, there was a drivers folder containing malware. Ignore that drivers folder as the only driver you need is Godiag J2534 Nano Device Driver from godiag.com tech support page.
This cable is exactly what I needed to connect my usb vag com obd-II interface to my Lincoln’s connector. all is right and good in the diagnostic world now. Well worth the money for the hardware. Durable and small enough to wrap up and put in the glovebox or tool case.
Tested with FORScan Windows version. 2015 F250 and 2020 Explorer, it worked with both. Solid connection at a reasonable price. I would guess that the seller is correct and it will work with other software and vehicle combinations that also use ELM327. The device appears to be well constructed and works as stated.
I tinker with working on cars and was looking for something better than the cheap wireless models you can find all over the place. But I didn’t want to spend hundreds to get a professional tool. This fits the bill. Included in the packaging is a link to download the application they recommend using with this tool. There are others as well if you search. This works great for a basic reader and can clear codes. It also allows a few more features than a standard scanner, with the right software. I wanted something that I could read with my old eyes. This connects to a laptop to use the tool. I have several older laptops that I use specifically for my auto repairs in my workshop. I have a rolling cart to keep the laptop on and I can just roll it out to the car, then use this to connect and sit down to review everything on a bigger screen. So far I have used it with a Windows 10 x64 system and it works good. I am not sure about other operating systems.
I have used several Bluetooth and wireless ODB II connectors in the past. They work well but you have to worry about the connection dropping. Using this practically eliminates that issue.
I only had to use the drivers from the website to get this up and running on my laptop. I use other 3rd party software to interface and it worked flawlessly for me.
For the average DIYer, this is everything you should need to get any codes so you can diagnose your vehicle problems. Also, you are able to clear any stored trouble codes. Another thing you can do is, is the proper software, view live data being streamed from your car.
ForScan is quite powerful and if you don’t know what you are doing, or you don’t pay attention, you can screw up your vehicle. You will need to scan your vehicle for the various modules, highlight the one you wish to update, and then press the programming button (a small triangle pointing to the right at the bottom of ForScan) to generate the setting codes which you will then be able to modify and write. When you do click the button to perform the data write it will tell you the checksum is not correct. Continue anyway and it will reset the checksum to the proper value.
