If you are tired of paying a mechanic just to tell you what’s wrong with your vehicle, you have probably considered purchasing an automotive code reader or scan tool.
When your check engine light goes on, these handy little devices help you get to the root of the problem. While you may still need a mechanic to actually fix the issue, owning a code reader helps you save time and money.
Because there are hundreds of these tools available, you need to do some research before making your purchase.
Innova 3020 Review
INNOVA 3020 is a versatile code reader that performs all the basic functions. It’s also handy for both the experienced mechanic and automotive tenderfoot.
Usually found for about $50, the Innova 3020 is a good buy. If you’re just looking to read and clear codes, however, there are cheaper model available, and you may be able to save some money.
With a variety of interesting features, the Innova 3020 stands out from the crowd, but there are a few drawbacks that you’ll want to be aware of.
Positives
Fool-Proof Lights: One of most noticeable features on the Innova 3020 code reader is the intuitive light system that gives you a general idea of whether or not your car has a problem. Three lights, green, yellow, and red, are located under the screen display. The green light has a check mark underneath it, and lights up when everything is okay. The yellow light has a question mark, and it indicates a possible problem. Finally, the red light with the large “X” tells you that a problem has been detected. These nifty little lights can be very effective for a quick and convenient diagnosis. They also help make the Innova 3020 more welcoming to people who have little or no experience using code readers.
Unique Display Screen: Most basic code readers don’t have a whole lot of information on the display screen. That’s not the case with the Innova 3020. Innova has a unique and patented display screen that shows 25 pieces of vital information. So while the green, yellow, and red lights are great for quick scanning, the display screen can give you detailed information should you need it. This is a nice feature for the experienced technician.
Automatic Refresh: While connected to the vehicle, the Innova 3020 automatically reads and refreshes information every 30 seconds. This is useful for confirming that a repair has been properly completed. For example, while other code readers may require you go through the scan process again and again to make sure that the error code is not coming back, this reader repeats the process for you, which can help save time and reassure you that the repair was effective.
Negatives
Go Online to Look Up Codes: While the Innova 3020 will give you the basic code, it will be up to you to find the definition and a solution for the problem. The tool might read “P0171”, but won’t tell you what it means. There are many websites that can be used to find the code definition, but having the information straight from the tool will assure you that you’re on the right track.
Not Upgradeable: Because cars and trucks are constantly changing, it helps to have a code reader that can keep up. Many code readers are upgradeable; the Innova 3020, however, is not. This can be a major issue if you drive new or exotic cars and need a code reader that can keep up with the latest technology. While the code reader is built to work on most 1996 or newer vehicles, it could potentially become obsolete in the future. An upgradable function could’ve solved that problem.
Bottom Line
While there are cheaper scan tools that do the basic read-and-erase functions just as well, the Innova 3020 is a versatile starter tool and is useful for both inexperienced auto tinkerers and master mechanics.
For the person in your household that has never used a code reader, the colored lights are a great feature. If you also have an experienced gearhead around, the data-rich display screen will help them get the details they’re looking for.
