How to use Innova 3020 rs code reader?
Every electronic equipment has a specific process of working. Innova is a renowned OBD II scanner and is so popular among vehicle users for its outstanding working efficiency. We can divide the working process of Innova into some different sections.
Step 01: Checking The Code
Turn off the engine of your vehicle. Keep your car’s ignition on. Plug in your scanning tool and turn it on. Now turn on the machine. Press the DTS button to check the trouble code and use the erase button to remove the existing code from your scanner. 
Caution: Do not press the ERASE button until diagnosing and solving the problem.
Step 02: Classifying The Problems
Innova 3020’s working process is unique. It reads and erases the trouble code and also determines if the problem is severe or not. When code checking is complete, you will get another signal to identify your problem type. There are three severities of signs. The lowest category of severity signal determines that the problem is so short and easy to remove. But, the highest peak of severity orders you to fix the issue as soon as possible. DTC severity alert and the different colors of lights are the signs of the different categories of problems.
- DTC Severity Alert
The severity alert of a trouble code scanner is essential for every vehicle user. It determines whether you have to fix the problem quickly or not. Suppose your vehicle issue is so severe that if you do not immediately fix it, you can not drive the car. In this time, the severity scale will go higher and show you the problem is so severe.
- Yellow, Red, and Green Lights
There are three lights just under the dial of the Innova 3020 scanner. Three lights are in three different colors. The green-colored light indicates that the vehicle is in a good position. The yellow color light means your car has some minor issues. But, the red light warns to repair the vehicle quickly because it indicates the most challenging position.
Step 03: Solve The Problem
The specialty of Innova is solving the general issues of a car without going to the mechanic. Innova reads and erases the trouble code, unlike the other regular OBD II scanners.
How to clear codes with Innova 3020 rs?
