1. Toyota Techstream – Best for Laptop

Mini VCI toyota OBD2 cable

Toyota Techstream software is the best value for money. You will get dealership-level software for a one-time payment of $30-60, depending on the store and your location. Having an advanced diagnostic tool like this without subscription costs is rare, and I advise every Toyota/Lexus owner to get this.

Pros

  • Full scan
  • Full live data
  • Service procedures
  • Bi-Directional
  • ECU coding
  • NO subscription cost
  • Cheap

Cons

  • Annoying installation process
  • No live data graphs
  • You need laptop

My experience with MINI-VCI J2534 cable

IMG 1425

The diagnostic software is top-level if there is a full scan, live data, and bi-directional features. The only missing thing was live data graphs, but you can still read them as a text value. I also did many customizations with ECU coding, like disabling seatbelt warnings, learning my keyfob to open windows, etc…

I tried this cable on my Toyota Corolla 2022 and was very happy with its ability. I dont have much use for the diagnostic and service functions since my car is almost new, and I dont have any issues yet. Read the full Toyota Techstream scan tool review here.

2. Thinkdiag2 – Works with all other car brands

Thinkdiag2 adapter

This is my favorite Bluetooth OBD2 scanner. It is made by Launch, so it is packed with professional OBD2 software. There is everything that Techstream can do, and you can use it with Android/iOS devices.

If you don’t own a laptop or want a tool that can work with Toyota and all other car brands, the Thinkdiag2 is the best choice.

Remember that Thinkdiag2 comes with a paid yearly subscription, so if you need a diagnostic tool just for Toyota, you should buy a cheap refurbished laptop and get Techstream. It will save you money.

Pros

  • Full scan
  • Full live data (with graphs)
  • Service procedures
  • Bi-Directional
  • ECU coding
  • Works on other 115+ car brands
  • Works on smartphone

Cons

  • Yearly subscription fee

My experience with Thinkdiag2

best scanners

Thinkdiag2 is a professional handheld scan tool packed in a little Bluetooth package. This is the scanner that I choose to always carry around in my car because it is so versatile.

This scanner is a perfect choice when someone asks me for help to diagnose a problem, read fault codes, or do a used car check.

It also does customizations with ECU coding, and that is what you are asked the most when your friends know you as the “OBD2 scanner guy” :D.

3. Veepeak + Car Scanner/Carista (low-budget pick)

Veepeak OBD2 adapter

This is the best budget tool you can get for your Toyota. Veepeak is the best cheap Bluetooth OBD2 adapter, and using it with 2 OBD2 apps will give you a lot of functionality for its price.

Those apps are Car Scanner ELM 327 for diagnosing problems, reading live data, and doing many other things.

And there is a Carista app for advanced ECU coding and some service functions that work with the Veepeak adapter.

Pros

  • Read codes from all modules
  • Engine live data (with graphs)
  • Service procedures (Carista)
  • ECU coding (Carista)
  • Cheap
  • Works on smartphone

Cons

  • No full live data
  • No Bi-directional testing

My experience with Veepeak

Bluetooth OBD2 scanner in smartphone.

If you don’t want to spend much on an OBD2 scanner, you will love the Car Scanner ELM 327 app. It is free, but you can buy an extension for only $5/lifetime.

It does a lot for being a simple Bluetooth adapter. It can read fault codes from all control units, which these adapters usually can’t.

This free app is enough to diagnose problems by reading fault codes and watching the live data in the engine control unit. It does have some ECU coding; I taught my Toyota the open/close windows from my keyfob.

But there can be no coding options for other Toyota models. That’s why you can do the coding with the Carista app.

There is a solution if you want to customize your Toyota, and the Car Scanner does not support coding for your model. You have to pay $10 for a 1-month Carista subscription, but you can cancel after the month is over, and your customizations will stay. Check these mods, I did with Carista for my 2022 Corolla.

OBD2 for Toyota FAQ:

Featured scan tools Techstream and Thinkdiag are best for all Toyota vehicles. They work flawlessly with Hybrid models, but you can expand the data monitoring with the smartphone app Dr.Hybrid which will tell you more about your EV battery.

For Toyotas, a simple Bluetooth scanner is often better than old code readers. It offers convenience, compatibility with mobile devices, and easy access to diagnostic information. Code readers are old technology and won’t provide as much information and functionality as a simple wireless dongle.

Yes, Toyota vehicles generally support OBD2 (On-Board Diagnostics 2) standard, allowing standardized access to diagnostic information. OBD2 started being implemented into Toyota vehicles in 1996 with their gasoline models first.
