Best OBD2 scanner for Toyota & Lexus
Finding the best OBD2 scanner for Toyota and Lexus can be a challenge. With hundreds of code readers and diagnostic scanners, we understand that it can be overwhelming for car owners to choose the best scanner for Toyota vehicles.
This article provides expert knowledge and research to help you identify the best OBD2 scanner for Toyota and Lexus vehicles.
1. YOUCANIC Full System Scanner
We tested a lot of scanners, trying to find the best scanner to use in our garage. What we found is that:
- Many scanner manufacturers make scanners that require a yearly subscription.
- It can diagnose one make but doesn’t work on all different car makes. You will have to pay more to cover other vehicle makes.
- Can’t diagnose all vehicle systems. May only diagnose the engine, airbag, transmission, and ABS problems. That’s only 4 systems. Modern cars can have up to 40+ systems.
- Don’t support bi-direction support for sensor testing and activation.
If you want a scanner that can do all these, you must spend thousands of dollars and most likely pay a yearly subscription.
So we decided to launch the YOUCANIC full system scanner that works on all makes and models.
The YOUCANIC full system scanner:
- Works on all makes.
- Can read and clear codes from all vehicle control units.
- View live data from any sensor.
- Bi-direction support to activate and test sensors and motors.
- Reset functions depending on the model.
If that is not enough, remember that the YOUCANIC scanner does not require a yearly subscription like other professional-level scanners. We believe that the YOUCANIC scanner offers the best OBD2 for the money for auto mechanics and DIYers.
Don’t want to buy a scanner? We still want to help you economically fix your vehicle. We created a scanner rental program that allows you to use the scanner for a few days on as many cars as you like.
We have many how-to videos showing you how to troubleshoot car problems. Once you get the codes, the YOUCANIC technicians can help you with any questions.
2. iCarsoft Toyota / Lexus / Scion / Isuzu Scanner

The iCarsoft TYT II scanner is a unique scanner that allows in-depth diagnostics on your Toyota, Scion, Isuzu, and Lexus vehicles. It provides coverage for all the systems on your car.

We have tested lots of OBD2 scanners. If you are looking for the best OBD2 scanner that is affordable and covers all systems on Toyota and Lexus vehicles, the iCarsoft TYT II Scanner is our top pick. You can recover this scanner’s cost the first time you use it to diagnose the check engine light on your vehicle.

3. Autel Maxisys Professional Diagnostic Scanner

The Autel Maxisys All System Professional Scanner is one of our favorite diagnostic scanners. It offers capabilities similar to those of the diagnostic scanners offered by Toyota dealers. Independent auto repair shops often use this scanner.
It cannot only diagnose multiple vehicle brands but also code the ECU and access all systems in all cars, including Toyotas and Lexus. It is also one of the most advanced Autel scanners you can use to diagnose Toyota and Lexus vehicles.
In addition to performing ECU programming, it can activate sensors and look at live data for any system installed in your car. It also offers bi-directional communication. This is the only scanner with similar capabilities to the official dealer scanner, the Techmaster, and Snap-On Solus.
The Autel Maxisys is the best professional diagnostic scanner for Toyota and Lexus and one of the least expensive. If you still want a professional diagnostic scanner for your Toyota but are on a tight budget, consider the Autel MaxiCOM or the older generation Autel DS708, which has come down in price significantly.
4. Autolink AL619 ABS/SRS Scanner

The Autolink AL619 scanner is a handheld scanner that will allow you to diagnose the Check Engine Light / Malfunction Indicator Light (MIL) and read, clear, and reset codes from the Anti-lock Brake System (ABS) and SRS/airbag.

This scanner is a cable for diagnosing Toyota vehicles with a CAN network. The AutoLink AL619 software can be updated via the internet to allow coverage of newer vehicles. It has limited system coverage compared to the other Toyota scanners in this list, but AutoLink AL619 is one of the best Toyota scanners under $100.
5. Techstream Technical Information System (TIS)
The primary diagnostic scan tool used at Toyota dealerships is Techstream. Until 2008, dealers used the Mastertech scanner. Toyota and Lexus dealers now use Techstream, which is backward compatible with older cars.
The Techstream scanner allows you to view and analyze vehicle data. Techstream 2.0 replaced the previous Techstream 1.0 scanner and will work on all of them.
The Techstream diagnostic scanner consists of three parts:
