How to Use Car Diagnostic Scanner?

The reason we have automotive diagnostic scanners is to be able to catch a malfunction in its early stages. As you will see, operating a scanner is a very simple and cost effective way for you to ensure that your car runs perfectly, and if there is an issue, you catch it in time.

Remember the importance of researching the issues on your own as much as possible to increase your understanding, which results in the proper care of your vehicle. We have included a basic outline of how an automotive diagnostic scanner works, but always remember that your product may vary, so follow the instructions in your manual, this is only a guide.

Step 1: Hook your scanner into the OBD-II connector under your dashboard. Most OBD-II ports are on the dash, and a little left on the steering wheel. Next, turn the key without starting the vehicle. Depending on the model and make of your automotive diagnostic scanner, follow and complete the instructions on the screen.

Step 2: If this is the first time you are using your scanner, you will want to check your VIN information. VIN stands for “Vehicle Identification Number”, and depending on your unit, can be found in the ‘vehicle information section’ of your scanner. You want to make sure that your vehicle’s information is correct before proceeding.

Step 3: Next, look for any DTC’s or diagnostic trouble codes. Each DTC will have a number, and that number is only for a specific fault for your vehicles make and model. Depending on your particular scanning tool, either save the data or write down the codes so you can do the necessary research.

Step 4: This step involves interpreting the codes, the act of troubleshooting. For instance, if you follow steps 1 through 3, and you obtain the code P0401 you now know it means that you may have an issue with an O2 sensor heater circuit. Most high-end scanners will have repair reports and troubleshooting tips, and research will determine whether you can repair the issue yourself, or take it to a mechanic.

Step 5: Once you have your codes sorted out you may now do a sensor scan. Depending on the unit you have purchased, you may have the ability to scan your system for issues that do not depend on warning light alerts. Things to scan for might be the water temperature, oxygen sensor, rpm, water and air temperature, oxygen-sensor function, engine load, ignition timing and rpm.

The Final Words (Summary)

As we have shown you today, with our brief article on how to find the best professional automotive diagnostic scanner, there are many benefits to owning your own professional grade scanning tool. First and foremost, these scanning tools can save you a lot of money at the repair shop, as they may diagnose an issue which you can repair yourself using the resources provided by your scanner.

While you can purchase the more inexpensive, basic code readers, we advise against it for the sake of your vehicle, as they cannot diagnose issues or scan your vehicle for issues. The high-end, professional grade scanning tools are the absolute best way to successfully diagnose any issues your vehicle may have, keeping it in top running condition and possibly saving you money in the long run.
