It pays to have an OBD2 scanner since it can record real-time issues with your car. You can find the Check Engine Light on the dashboard, usually on the tachometer or speedometer of your car. However, when it happens again, it becomes an active code, triggering the light to illuminate.

If detected for the first time, it records it as a pending code without tripping the Check Engine Light. When the onboard computer detects car problems, it records them as diagnostic trouble codes. You connect the scanner using a data link connector to the port of your car, just below the steering column so that it can record all the data regarding your vehicle. They also gauge fuel consumption, emission control systems, road speed, and similar issues by recording live data and recording trouble codes. OBD2 scanners read the On-Board Diagnostics of your vehicle, an onboard computer found inside all modern cars that help monitor car problems such as safety features like airbags and seatbelts.

How does an OBD2 scanner diagnose your car? When it flashes after it lights up, your vehicle has serious issues. Check your car when the Check Engine light turns on the first time. When it happens the second time, the vehicle reads it as an Active Code, and the Check Engine indicator turns on. On the other hand, pending codes are trickier to see since it does not cause the Check Engine light to go. When your vehicle signals to check the engine, it has detected active codes. The scanner will instruct you to choose between Active Codes and Pending Codes. Usually, though, you'll have information on different systems on your car, including engine/powertrain, transmission, airbag system, and brakes. The information it provides depends mainly on your scanner and the year of your vehicle. Select Codes or Trouble Codes on the main menu after booting up your scanner. The advantage of these tools is their ability to tell you the trouble with your car in plain English rather than in codes, on the scanner itself, or using their companion app. While they are slightly pricier than OBD2 readers, this is often worth investing in if you care about maintaining your vehicle correctly. These scanners can monitor engine conditions such as fuel pressure - a vital component that many people give little attention to when it comes to their car or truck maintenance. This combination gives vehicle owners a better idea of what's going on under the hood. These tools offer lightweight design and connection to an app on your smartphone, for example. The scan tool is far more advanced not only can they clear any stored trouble codes but also view live data too. If you buy the code reader, it will only allow you to clear codes and read codes.

If you don't have previous experience using it or are unfamiliar with trouble codes, you may need independent input to get the information you need. However, this device comes with limited access to information on manufacturer code and other similar data.

It costs within the range you usually spend in having a professional mechanic diagnose your car, only that you can use it multiple times. The OBD2 code reader can perform these checks and can help you resolve vehicle problems in-house. Modern vehicles have a standardized system for diagnosing errors in the car's engine. To use an OBD2 scanner, connect your scanner to the data link connector on your car, input the car's information found on your car's instruction manual, if prompted, then scan your vehicle.
