If your answer is yes, there’s a lot you have to consider. Do you really need that super expensive Innova scan tool, or you are purchasing one that is below the standards you need?

With the wide range of Innova scan tools available in the market, it’s not surprising if you have any doubts and confusions about which one you should choose. Our comprehensive buying guide breaks it all down for you. 

Buying Guide

In this section, we will cover all that you need to know about buying an Innova scanning tool, before diving into the best products. Based on the information we provide below, you can consider which one is right for you.

What is an Innova Scan Tool?

When it comes to scan tools for a wide range of vehicles, the ones manufactured by Innova are one of the best today. From entry-level tools to the most expensive ones, there are a lot of Innova code readers and scan tools you can find, some of which are OBD1 or OBD2 compatible.

If you’re unfamiliar with what Onboard Diagnostics is, OBD, it might be even more difficult to find the best one. These systems allow vehicles to assess themselves, diagnose and identify different problems, and send reports to the owner or user. Cars released before 1996 are OBD1 compliant, while those released afterwards are OBD2.

After the OBD system has diagnosed the problem, the user needs to view the report, and this is where the scan tools come in. These diagnostic scanners show the reports in the form of codes.

4 Steps to Choose the Best Innova Scan Tools

Step 1: What Type of Innova Scan Tool is Suitable for You?

Firstly, consider the type of scan tool that is suitable for the kind of driver or car owner you are. Everyday car owners are more suitable to use code readers, which can check a wide range of regular diagnosis.

It will read and analyze the trouble codes on the dashboard, read DTCs, display the readiness status, locate bad O2 sensors, and turn the check engine light (CEL) or the MIL off. It can also be used to reset the monitor, read live data, recollect the VIN of a vehicle, carry out an EVAP test and prepare for a smog check.

But, if you’re a car mechanic, technician or simply an experienced DIYer, you’ll do better with a scan tool. The scan tool does more than just regular diagnosis but also offers special service functions. When it comes to the diagnosis of the standard system, the tool can be used to control the system and check the error. Enhanced codes like ABS, TPMS, SRS, SAS, Light System and Fuel System can be read.

Apart from these, you can also take care of service functions like resetting the SRS, TPS, EPB, SAS, and more. It can also be used for battery tests.

Step 2: Compatibility/Vehicle Coverage

There’s no point in purchasing an Innova scan tool if it cannot be used with your vehicle. Depending on the make, model and year of your car, you need to purchase one that is compatible with it. If you purchase the wrong one, it ends up being a waste of money and time. 

Some of the scan tools are compatible with OBD1 vehicles, which are cars made before 1996. But those that are suitable for OBD2 vehicles are cars that were made after 1996. Thus, you should check the year that your car was made and look out for the scan tool that is compatible with that particular year. It’s also important for the scan tool to be suitable for mainstream vehicles.

You also have to ensure that the Innova scan tool is suitable for both domestic and foreign makes, in case you’re using an imported car. Some tools work with a majority of cars while others are missing the codes for foreign cars. For instance, some scan tools don’t work with Asian-made cars but only with American-made cars.

Finally, it must be compatible with all models, from Ford and Toyota to Honda and Jeeps and other models. While some scan tools cannot read the codes on some models, others will work with a majority of mainstream cars. 

When considering these three: the make, model and year; you can then decide which of the scan tools are compatible with your needs, preferences and car type. The Innova scan tools usually include what they are compatible with in their features.

Step 3: Pricing

The next thing you have to consider is the price of the Innova scan tool. It’s important to work with your budget when purchasing the scan tool. At the same time, you should not sacrifice affordability or cheapness for quality, or this will end up being counterproductive. There are many scan tools that you can purchase without spending past your budget and will still be of high quality. Innova is known for these kinds of tools, so you can enjoy the affordability and high quality. 

If you’re new to DIYing or mechanics of a car, or even new to the whole concept of OBD, it’s best to use a card reader. If you’re purchasing a high-quality card reader from Innova, you will spend between $50 and $150, so set your budget to be between this range. This is also ideal for average car owners who just like to have a scan tool at hand.

But, if you’re planning to use the Innova scan tool for more technical matters like fixing a car, you need a more expensive, high-end model. Mechanics usually look out for expensive scan tools which can provide special functions while they diagnose and fix cars. Experienced DIYers and technicians can set their budget between $150 and $300, as long as they are purchasing one manufactured by Innova.

If you purchase an expensive model when you only need it for everyday car functions, it’ll end up being a waste of money. Also, if you buy a cheap model for more advanced, technical functions, there will be a lot of limits to what you can do.

Other Considerations

Apart from the three main considerations explained above, there are other minor factors you should consider if you want to better enjoy your Innova scan tool. These can add special functions to the scan tool, make it easier or more convenient for you to use, and even come with different software.

For one, you can purchase a device with a screen, usually between 2.8 inches and 3.5 inches. Some of the screens are also backlit and have all-in-one features, making it easier for you to view many types of data at a time. This includes the diagnoses codes and their different definitions, and this is especially useful for car owners.

Another important feature that you can look out for when choosing Innova scan tools is its software updates. While some tools come with lifetime software updates, others even go far and allow you to update them easily on your personal computer or mobile device. 

If you don’t speak English or work with non-English speakers, different Innova scan tools come with multilingual options. They present the codes to you in mostly English, French and Spanish. 

Finally, the portability of the Innova scan tool is important. Since it’s meant to be a handy tool, you should look out for those that are easy to carry, hold and have a lightweight design. 

When you take all of these factors into consideration and follow the steps from start to finish, you can choose the right kind of Innova scan tool that meets your needs and suits your preferences. Now that we have covered how you can best choose the tool you want, we can dive into the best four Innova scan tools so you can decide which is the best among them.
