Step 2: What Type of Toyota Scan Tool is Suitable for You? 

OBD1 or OBD2 Scanner

So what you need to specify here is knowing if your vehicle runs on an OBD1 or OBD2 system. While some code readers will not be able to read OBD1 systems as it could be seen as an old or slightly outdated system, most scan tools on the market today are made for OBD2 vehicles. 

Not many OBD2 scanners can diagnose vehicles before 1996 and 80’s models. If your vehicle is running an OBD1 system, then Actron CP9690 Elite is built for you as this diagnostic tool covers both OBD2 and OBD1 cars. Also, it comes with OBDI Cables for 1984-1995 GM and Ford vehicles and 1989-1995 Chrysler and Toyota.

For OBD2 systemized vehicles, Autel AutoLink AL319 or Carista is an excellent choice.

Wired or Wireless Tool

Suppose you prefer turning your smartphone or tablet into a scanner and moving around while diagnosing the car. In that case, my advice is to buy a cheap Bluetooth or WIFI scanner like BAFX Products or Foseal WIFI adapter for iPhone iPad and Android. Otherwise, an affordable car code reader like Autel AL319 is just perfect for you.

Step 3: Compatibility and Vehicle Coverage

On the compatibility side, it is essential to know which vehicles each scanner is compatible with. For example, Carista only supports Tire Pressure Monitoring Sensors (TPMS), ABS/VSC/TRAC inspections, and Detailed ECU information. Unfortunately, Carista can only support these advanced systems on your Toyota, Lexus, or Scion. It is dependent on each car make and model as to which different features Carista supports.

Actron CP9690 Elite meets both OBD1 & OBD2 systems for Toyota. For OBD1 cars, you are a little limited as far as functions go, as you can only check codes and read LIVE engine data. For OBD2 vehicles, you can access and read enhanced codes such as SRS (Airbag), ABS (Anti-lock Braking System), RPM, Fuel Pressure, Coolant Temperature, etc.

Step 4: Pricing 

If you are a newcomer to car scanning tools and vehicle diagnostics, don’t worry, you do not have to spend too much. You would pay from 25 – 50 Dollars. Toyota Diagnostic Scanners surpassing this cost have increased advanced features that you simply will not use. Don’t waste your money on a more complex scanner; you may just get confused by all the additional functions.

For someone in the motor trade or an experienced DIYer, you will need something that can get into those functions and systems of further advancement, so you can expect to spend a little more. A scan tool will cost you anywhere between 50 and 200 dollars, depending on the diagnostics level you wish to achieve.

You should only pay from $25 – $50 Dollars for a Toyota Scanner like Foseal WIFI code reader if you are a newcomer to car scanning tools and vehicle diagnostics.

Step 5: Other Considerations

Is there anything else I should take into contemplation before deciding to buy one of these scanners?

* Why can Toyota, Lexus, and Scion all Use The Same Scanner?

This is because Toyota, an automotive provider, produces vehicles of five different brands. These brands include Toyota, Ranz, Lexus, Hino, and Daihatsu, and Scion is a discontinued marque of Toyota that debuted in 2003. On February 3, 2016, Toyota announced that it would cease the Scion brand in August 2016, with selected models rebranded as Toyota vehicles for the 2017 model year. However, Scion was discontinued, which does not mean they are not a part of the family, as, of course, some of their vehicles are still on the roads today. So long story short, they all support and use similar parts and systems. 


Something to bring up to thought is the connectivity of the device towards the vehicle. Would you prefer to have a cabled or wireless scanner? That being said, while there are wireless scanners, most of the OBD1 scan tools are corded, like Actron or Autel. So if you have an OBD1 systemized vehicle, you might not have as much room for flexibility. 

As for the wireless scanning tools, Carista, Foseal, and BAFX as examples, they sometimes come with different variables. Some are connected via Bluetooth, and others are connected via Wi-Fi. If your Wi-Fi goes down, that could be a problem, especially if you are in the middle of acting like an ECU update. If you’ve got a strong Wi-Fi connection, you should not run into any problems. 

* Techstream Software

An additional aspect to take into consideration is, do the devices have access to Toyota’s Techstream software? – A diagnosis software designed specifically for Toyota Lexus or Scion vehicles.

Toyota developed Techstream for internal use and customers who want to be a little more hands-on when dealing with their car.

To diagnose issues with your vehicle, Toyota Techstream is a software designed to connect and interact with your car’s internal computer. It will read the sensors and alert you of any errors it finds by providing you with error codes. Aside from the trouble codes, you can also access and modify your vehicle settings, turning certain features on or off.

Best Toyota Scanning Tool Review

1. Carista

Carista review
Carista OBD2 Bluetooth Adapter
Carista is an excellent little attribute to the box because your smart device is your diagnostic instrument.

A nice part about Carista, it’s one of the inexpensive scanners in the range. Carista is an excellent little attribute to the box because your smart device is your diagnostic instrument; you’ve got a scan tool readily available to you only by owning a phone or tablet and an OBD2 connector. Carista is compatible with android and iOS applications. 

In terms of functions, Carista can reprogram certain systems, remove warning lights, check locks, and other condolence without advanced devices. Carista’s OBD2 adapter comes with a 1-month free trial of all paid serviceability in the Carista app.

Most of the customers who bought this device said it was quick and simple and exactly described. On the other hand, they were not happy that they had to pay additional fees for the app and said that there was upselling and advertising promotion within the app itself.

The AL319 will work on most 1996 vehicles and newer vehicles. It runs OBD II and CAN networks, domestic and imported. It has a bright color-coded LED screen and built-in speakers to provide you with both visual and audible indications for readiness verification.

A scanner with customer quotes that scilicet: “Such a helpful diagnostic tool.” “It’s at a low cost, it saves you money and helps you get the job done!”. One customer even said it had saved him close to 5000 Dollars from the dealer to replace the hybrid battery on his 2010 Toyota Prius.

Other clients were a little disappointed that it did not work with every single vehicle.

Overall this is a very good handheld Toyota code reader/diagnostic tool at a hugely affordable price of just under 40 Dollars!

4. BAFX Products

BAFX Products review
Bafx Products OBDII Diagnostic Car Scanner
BAFX is so perfect for beginners as it is effortless to use.

The BAFX products scan tool is a well-established monitoring, analytical, and secure OBD reader compatible with vehicles purchased in the USA. It can work on all of them considering that they have a year model of 1996 or state of the art, irrespective of the manufacturer! Cheap OBD II Bluetooth reader companies say that they will work on OBD II cooperative vehicles, but the bulk of them appear to malfunction while working on cars that use the J1850 or CAN protocols.

A buyer of this product reports he had been in the automotive industry as a professional for around 20 years and had an ASE Level 1 specialized certification in advanced diagnostics. He said that this was one of the best OBDII scanners he has ever seen at such a low price. A lot of things that the higher-priced equipment can do, unfortunately, it will not do, but for fast and easy checks and looking over live data lists, it was very successful!

If using the BAFX Bluetooth scanning adapter, diagnostic trouble codes (DTC’s), you shall easily be able to read and clear! Read engine statistics and display data as well as your vehicle speed (RPM), long and short trim fuel data, advanced timing, the flow rate of your Air Intake and Air Temperature, O2 Sensors, and the list does not end there with the functions available to you!

A little setback I find for this scanner is that it is only compatible with Android, but it also has an IOS compatible version.

FAQs about BAFX Products:

Q – Can it be used on 2008 Lexus RX 350?

A – Yes.

Q – Is this compatible with Android 8.1?

A – Yes.

5. Foseal WiFi OBDII Scanner

Foseal review
Foseal WIFI OBDII Bluetooth Toyota Scanning Tool
If you are on a tight budget and don’t want to seek out a technician, Foseal Car Wifi is a perfect choice. It is not complicated and offers a read and deletes error codes easily.

The Foseal scanner has been described as “the kind of tech that only F1 teams had 20 years ago.” The Foseal scanner uses third-party apps to operate its functions. From dyno’s to performance meters and real-time telemetry, e.g., boost and throttle position, fuel mixture, spark timing, intake temperature, current torque statistics, engine power, demand percentage, real-time rpm and boost psi, throttle position, and hundreds more!

Customers overall seemed very happy with this device and praised its use. Although some complained about its connectivity, I did some research, which tended to be down to buyers’ phones causing problems or the third-party apps. Therefore, if you decide to buy this scanner, do a little digging as to which app works best with it, which may depend on your car make and model as well. Still, it’s something that’s not too hard to find out.

An ASE certified mechanic found that the OBDCarDoctor application worked well with this device, and he exclaimed that the device was hassle-free and easy to use.

FAQs about Foseal WIFI scanner:

Q – Does it work with Lexus IS 250?

A – Yes.

Q – Would this work on a scion TC 2005?

A – Yes

Final Thoughts

When it comes to buying a scanner for your Toyota, Lexus, or Scion, all of these scanners are perfectly adequate. Before buying the scanner, you will need to specify if your vehicle is running on an OBD 1 or OBD 2 system. What you get out of each scanner is also how much you want to spend. If you’re new, don’t go overboard and get the most expensive scanner, a cheap one will do the job!
