OBD2 Scanner Buying Guide
Getting Started with OBD2 Scanner
First things first, Reading the article about OBD2 scanner background working information, how does OBD2 scanner work? and how to use It?
Car manufacturers use first invented On-Board Diagnostics (OBD) to easily see what the engine and other functions say before making the fix. This feature was integrated by car companies in 1996 and has become a standard feature.
On Board Scanner helps mechanics to narrow down and pinpoint the cause of internal errors in the vehicle before attempting a fix. This way, they were able to cut the cost of diagnostics which involved a thorough scrutiny of the vehicle in finding error source.
Now, On Board Scanner has evolved and gave birth to some other better methods of diagnosis. With the more advanced computer age, the OBD2 scanner was born. This is a more advanced diagnostic tool that covers more parameter and includes the latest car models.
Today, these scanners are not exclusive to car manufacturers. This scanner tool is up for grabs for anyone who wants to check their automobile’s overall health.

How to Access Your Car’s OBD2 Codes: A Step by Step Guide
It can be daunting whenever you see the Check Engine Light flashing on your car’s dashboard in the middle of a drive. The sign makes you panic, and you tend to rush over to an auto shop to find that it was just a moment of glitch.
To prevent such frustrating events, it’s better to learn how to check your car first before going out of your way for something that could be insignificant. In this guide, you’ll learn how to do just that by accessing your car’s OBD2 codes whenever the Check Engine Light signal appears on the dashboard.
OBD2 Codes: What You Must Know
You need to learn what exactly are OBD2 codes and how reading them can help you and your car. Check out the ultimate guide to understand more about reading OBD2 codes and what OBD2 codes Mean.
Technically, OBD2 or OBD-II is a code formatting that makes Diagnostic Trouble Codes (DTC) readable when retrieved from your car’s computer. DTCs are data stored by your car’s On-Board Diagnostics (OBD) system to describe any issues detected in your vehicle.
When the Check Engine Light flashes, it lets you know there’s something wrong, but doesn't tell you precisely what. That's where OBD2 codes help. By accessing and retrieving these codes, you get to know what and where exactly is the problem in your car.
When you know what the problem is, you can better decide on what to do with your car. If you have some automotive knowledge and skill, you can try to fix the problem on your own. If you find that it’s a serious issue that needs some serious fixing, then you’ll have no doubts in bringing your car to the local mechanic.
You see, the Check Engine Light doesn’t always reflect an issue that needs a repair. But if you can check and read the codes whenever that happens, you’ll be able to decide appropriately and worry less.
Step by Step Guide to Accessing Your Car's OBD2 Codes
1. Know your car’s make and mod
Knowing the model and make of your car is basically how you’ll know where to start. The OBD2 coding system is primarily adopted only by vehicles that have been manufactured from the year 1996 onwards.
If your car is an old model that was made before 1996, then your car probably uses the OBD1 or OBD-I coding system. Reading OBD1 codes is much more complicated because you'll need specialized tools to do just that.
If you confirm that your car is an old model that uses OBD-I codes, there’s no better way of checking it than bringing it to an auto shop. Old models made by different manufacturers might require different methods of retrieving OBD1 codes. It may not be something that you can do for sure on your own.
If you confirm that your car is a new model, then you’ll have it easier because there are plenty of tools that you can use to access OBD2 codes.
2. Choose the right OBD access tool for your car.
When you confirm that your car uses OBD2 codes, it’s time to choose which OBD tool you should use. There are two main types of OBD access tools to choose from:
- OBD2 code reader
OBD code readers are the most straightforward access tools and also the cheapest. These are handheld, easy to use tools that retrieve and read DTCs. When there's an issue detected, the OBD2 codes are displayed on the gadget's screen.
However, this gadget only reads and displays the codes. To know what the retrieved codes mean, you need to use a separate OBD2 code reference for detailed information on the codes. This information can be obtained using your car’s repair manual, your OBD tool’s manual, or available online sources.
If you don’t do DIY repairs on your car and only need to access the codes and have time to search for additional information on the codes, this gadget would be the most practical choice. But if you need your gadget to do more, then you should consider getting the next type of tool.
- OBD2 code scanner/scan tool
OBD code scanners are pretty much the same as OBD code readers, but they pack additional helpful features and are also pricier. These tools don’t only retrieve and read OBD2 codes, and they even interpret these codes.
OBD scanners can provide detailed definitions of virtually all generic OBD2 codes and some manufacturer specific codes. Professional mechanics opt to use this type of tool because it saves them time at work. This gadget would also be the best option if you have some automotive knowledge and repair skills so that you can perform quick fixes on your car.
3. Connect your tool to your car’s OBD port.
Once you’ve obtained your tool of choice, next is to plug and connect it to your car’s OBD port. Usually, the OBD port can be found under the dashboard, near the driver’s pedals. The port should be a female connector with 16 pins and is shaped like a trapezoid.
Plug your OBD tool’s male connector to the female port. This should be easy enough for anyone. Once your gadget is properly connected, it should turn on automatically and start scanning or retrieving DTCs.
4. Read and record the codes.
After a short while of scanning, your OBD tool will read and display the codes on its screen. If you are using an OBD2 code scanner, you should be able to directly access and understand what the codes mean.
If you are using an OBD2 code reader, you should record or write down the codes on a note pad. This is so you can search for further information on them or show them to your mechanic later.
Additional Actions and Recommendations
Now that you’ve successfully accessed and read your car’s OBD2 codes, you should plan and decide on your next actions.
First, you should understand what exact problems those codes refer to. You can do this by looking through your OBD2 codes reference. If your car or OBD tool’s manuals do not have information on OBD2 codes, you should download a copy from online sources so you can have access to that information at any time.
Next, you should inspect the part of your car where the issue was detected. Doing so will allow you to decide whether you can try to fix the problem on your own or if you need professional help to look further into it. If you can't perform the inspection, then you should have your trusted mechanic do it for you.
Last but not the least; you should take note of all the issues that are frequently detected in your car. By knowing the frequency and pattern of recurring problems, you can better measure your car's capacity and performance. That way, you can come up with an actionable plan on how to prevent those issues in the future.
An OBD2 scanner will help you diagnose and monitor the health of your vehicle. If you are not an auto-mechanic, maybe you don’t see this to have an extensive use. However, considering the cost of labor, doing it yourself will give you more savings!
With frequent monitoring, you can also prevent expensive damages to your vehicle and pre-emptively counteract impending system failures!
