Carista OBD2 Bluetooth Adapter and App

Carista OBD2 Bluetooth Adapter and App
4.24.2 / 5
It’s ideal for mechanics, professionals, and DIYers as well. Carista is one of the most affordable options.

OBDII Functions

Carista provides free access to all OBD2 modes and protocols. This includes reading Toyota engine codes as well as generic trouble codes. Carista doesn’t just give you the codes, either. You can also look-up their meanings, helping you identify the true root of your problem. 

System Diagnosis

The Carista adapter gives you access to more advanced diagnostics than what you get in OBD2 for many vehicles. Toyota is one of those brands, making Carista a great Toyota diagnostic tool for reading airbag codes, ABS codes, and other specific systems.

There is a caveat to this diagnostic power, however. To access and read advanced diagnostics, you’ll either need a paid app subscription or to use a different third-party app. Keep that in mind if you’re eying this up because of its low price. 

Special Service Functions

The range of special functions in the Carista app is impressive. It goes beyond diagnostics and gives you access to personalization modules, sometimes even features you didn’t know your car had. From the window controls to reprogramming your lights, you can do a lot with Carista—if you’re willing to pay for it. Again, these features are only available with a paid subscription.

The Actron CP9690 is a powerful OBD2 scanner Toyota owners will love. It can also diagnose OBD1 vehicles, making it the most widely-compatible Toyota diagnostic tool on the list.

OBDII Functions

Finding an OBDII scanner that will work with older vehicles can be tricky. That’s the biggest advantage of the Actron CP9690 compared to the other scanners we’ve looked at. This is the best Toyota scan tool for older vehicles, since it can read both OBDII and OBDI trouble codes. 

Along with the compatibility, the Actron CP9690 is comprehensive in its OBDII functionality, as well. All data can be viewed in real-time, displayed graphically, or recorded and viewed later. 

System Diagnosis

Special Service Functions

As powerful as the Actron CP9690 is for diagnostics, its service functions are limited. You can reset the basic functions, like the oil and battery light, but don’t expect to do any customizing or ECU reprogramming.

The Autophix OM500 is the best Toyota code reader for buyers on a budget. While its diagnostic functions are more limited, it’s the most affordable way to quickly and accurately read and clear trouble codes.

OBDII Functions

For running OBDII tests and reading DTCs, the Autophix OM500 definitely outperforms its price point. Even if you’re not a car expert, it’s easy to check, read, and clear the codes. You’ll also see if the code is generic or specific to your Toyota. 

Unfortunately, the Autophix OM500 doesn’t support all the OBD2 modes. You can’t check the freeze frame data or run oxygen sensor tests, for example.

System Diagnosis

We love that the trouble code definitions come right up when you read a trouble code with the Autophix OM500. This is a nice time and effort saver. As a Toyota scan tool, the emphasis on Japanese-made vehicles makes the Autophix OM500 both comprehensive and accurate. It reads all Toyota-specific codes in addition to generic ones.

Special Service Functions

Here’s where you see how they keep the Autophix OM500 so affordable. You can’t check on all your car’s systems using this Toyota scanner. For resetting other warning lights, you’ll need to look at a higher price point.

4.44.4 / 5
As a diagnostic tool, the Autel MaxiLink ML619 provides fast, easy to read reports on all OBD2 tests. Beyond that, though, its features are a bit limited.

OBDII Functions

The Autel MaxiLink ML619 has wide OBD2 compatibility. Every protocol is supported, and it will read codes that are specific to Toyota as well as the general ones. That comprehensive diagnosis is its strongest feature.

You can run all 10 modes of OBD2 with the Autel ML619, as well. Live data streams and freeze frame reports can be displayed with text or graphs. The MaxiLink ML619 also makes it easy to save and print your data.

As a diagnostic tool, the Autel MaxiLink ML619 provides fast, easy to read reports on all OBD2 tests. Beyond that, though, its features are a bit limited.

Final Thoughts

The first question you need to ask yourself when you’re looking for a Toyota scan tool is what year your vehicle was made. Most vehicles made after 1996 are easy to find scanners for, but your options are more limited if your vehicle was made pre-OBD2.

Beyond this, it comes down to form and function. Something like the Carista tool can give you the most functions for your money—if you’re willing to work with the free compatible apps. Most people will find it easier to use a hand-held scanner.

Think about which systems you want to diagnose and repair at home, as well. If your main concern is reading and clearing codes to turn off the check engine light, an affordable option like the Autophix OM500 might be all you need. For advanced electronic system diagnosis or resetting other warning lights, expect to spend a bit more.

If pressed to pick one winner, our money has to be on the Foxwell NT510 for its wide compatibility and functions. These are all excellent Toyota tools, however, that will make home diagnostics a breeze.
