With new technology comes new problems. The advent of diagnostic systems for cars has led to the problem of choosing the right type of OBD scanners for your specific type of car. Since its introduction in the 1980s, the OBD system has experienced phenomenal advancement, and its use has become more widespread.
The usefulness of OBD scanners in getting you more control over your car and allowing you an optimal driving experience has ensured this. For this particular reason choosing OBD scanners, especially for specific car brands might prove to be a bother as there is an endless array of OBD scanner options.
However, before we proceed to discuss the best OBD II scanner for your Toyota, we shall be talking briefly about what OBD scanners are, their functions, things to consider in choosing the suitable OBD scanner for your vehicle.
What are OBD Scanners?
OBD means On-Board Diagnostics. It is a system used to read a vehicle’s computer system and diagnose any issues. An OBD system is used to establish a connection between your car and the diagnostic software or application. What an OBD scanner does is grant you access to data about your vehicle, from error memory to real-time data. You should also note that depending on the sophistication of the scanner; you might also have access to customization features, basic repairs and car hacks.
What are OBD II scanners, and what makes them different?
OBD II scanners are a giant leap from the initial generation of the onboard diagnostic system called OBD I. OBD I scanners were made based on the vehicle’s emission control systems. The information provided by the OBD I scanner was severely limited as it only triggered the malfunction light (idiot light) in cars and could not offer any real diagnostic or repair solution.
Following the standardization of OBD scanners in all vehicles made after 1996, there has been a significant advancement in the technology. With an OBD II scanner, you not only get information that something is wrong with your car: you also get information on what is wrong: you get reliable information that can be easily transmitted remotely via Bluetooth or Wifi.
The OBD II scanner performs all the functions of the OBD I scanner with increased versatility and accuracy. With an OBD II scanner, you get additional information, customization, car use data history, and performance level information.
Why are they necessary?
Before the advent of OBD II scanners, whenever there was a car issue that needed to be fixed, the major option was to visit the mechanic, which, let’s face it could be both expensive and time-consuming. With the proliferation of OBD II scanners, we have what can be considered a less expensive option in the long run. With an OBD II scanner, you can very conveniently get an assessment of your vehicle and even determine what the best course of action would be on your own.
OBD II scanners have the ability to check important functions in your vehicle such as the exhaust emission levels, fuel pressure and other important metrics. The availability of your vehicle’s assessment allows you to know what state your vehicle is in at every point in time, allowing you to save on maintenance and repair costs.
With the upgrade of the On-Board Diagnostic system from level I to II came more reliable and quick diagnosis. You can sufficiently rely on information provided by your OBD II scanners, and there’s the added advantage of the information being provided in simple, easy-to-understand language.
Asides providing you with the information needed to diagnose what is wrong with your vehicle, OBD II scanners prevent you from driving blind, literally, especially in bad weather conditions.
How to Use an OBD II scanner
The OBD II scanner is relatively an easy to use tool. It doesn’t take an Einstein to figure out how the system works. Following the standardization of OBD II scanners, most cars manufactured after 1996 feature a Diagnostic Link Connector (DLC).
A DLC is used to interface between the Powertrain Control Module (PCM) that is your vehicle’s brain and an OBD II scan compliant tool. To make use of an OBD II scanner, you have to find the DLC. You can do this by referring to your vehicle user’s manual.
After locating this, you connect to your scanner. Depending on the type of scanner you have, you might require a wired cable for this. Again, different scanners have their peculiarities.
Some scanners may require that you keep your car running after connecting to the DLC while some others would require that you keep the car in idle mode.
Connecting your scanner to the DLC allows both systems to communicate. You will then be required to input details such as the Vehicle Identification Number, model, type, engine etc. requested by the scanner after which you select the scan option.
Once your scan is completed, the scanner will provide codes or an error message. You can then interpret what these codes mean using the instructions manual or by searching on the internet.
The above guide on how to use the OBD II scanner is a general market guide and you may in addition to this have to study the instructions manual.
Different types of OBDII scanners
In the previous section, we kept making reference to the peculiarities of each scanner as a factor to consider in the use of your OBD II scanner. In this section, we shall be examining the two broad categories of OBD II scanners that are available in the market today. This would help us to better understand the way different scanners operate. All this background information serves the ultimate purpose of enabling us to select the best OBD II scanner.
Basic Code Readers
Code readers are usually the cheaper option available. This is because it is less functional than the scan reader. Code readers perform the basic function of reading the codes, and that’s about it. Despite its limited use, a code reader is a great tool to have for a car owner who wishes to save on repair and maintenance costs.
Scan tools
A scan tool is a more sophisticated version of the code reader. Asides reading the code like the basic code reader, a scan tool enables you to read the code and clear it. It also gives you access to comprehensive data, and some sophisticated versions of the scan tool can control or customize the vehicles onboard software.
However, you should note that not all scanners are the same, and the more features a scanner has, the more expensive it is likely to be.

What makes a good scanner: Factors to consider when choosing an OBD II scanner
If asked, every scanner manufacturer will claim to have the best scanner out there in the market. But we all know there are many sub-par or even outright terrible products out there. In choosing the best scanner, certain questions must be answered. Does the product do what it claims to do? Is the product available? Is it easy enough to use?
In choosing the best scanners, here are some factors to consider
- Ability: In choosing an OBD II scanner, the first thing to consider is the features of that particular product. How well does it perform? Is it just a basic code reader or a scan tool? (see previous section). A good scanner must have the ability to provide and store data within a short time. One of the reasons why OBD I scanners are not desirable today is that they lack speed and the ability to perform a wide range of functions. Therefore, choosing an OBD II scanner that does very little more than the OBD I scanner makes little sense.
- Ease of Use: OBD II scanners are used by different categories of people ranging from the novice car owner to the automobile obsessed DIYer to the auto-mechanic. A good scanner must serve the needs of these different categories of people, which means it must be easy enough to use by the novice user.
- Universality: A good scanner should be compatible with most vehicles, including those that are not OBD II enabled, i.e. vehicles made before the second generation of OBD scanners. It should also be adaptable enough for use on different platforms like smartphones, tablets, laptops. Another thing that would make a scanner more desirable is being upgradeable. No one wants to be stuck with an OBD II Scanner that does less than its counterparts for the longest time neither does anyone want to have to pay for a new scanner every now and then.
- Versatility: A good OBD scanner must be versatile enough for easy movement. It should also be designed with alternative power sources and wireless capabilities.
- Good value for money: The fact that an OBD II scanner has passed the aforelisted metrics does not mean that it has to be ridiculously priced. However, we understand that the more features a scanner has, the more expensive it is likely to be. Yet, we insist that it must be a good value for money.
Considering all the aforelisted and consumer feedbacks, we have selected the top six OBD II scanners for Toyota. In no particular order, our top selections are;
