A car is an important investment that you must take good care of. It is also essential to have a safe and hassle-free journey. There are times when you hear a disturbing noise coming from your engine, but you find nothing when popping the hood. Having a car diagnostic tool can help you in this situation and can help you to understand what is wrong with the car.

When to Use the Car Diagnostic Tool?

Car diagnostic tools will not fix your car’s problems on their own. If you want to make the best use of these tools, you will have to know when to use it. Here are a couple of situations –

  • When the check engine light is on: The check engine light represents several problems that can take place in your engine, transmission, or exhaust systems. If you want to know what the light is indicating, you can use the diagnostic tool to get the job done.
  • Record vehicle performance/statistics: There are a few higher-end car diagnostic tools that can do more than reading engine codes. You can use more advanced tools to take live data measurements of the vehicle’s systems. It will help you to fine-tune the setup.

Tools you can use

  • OBD-II diagnostic tool: This tool will allow you to read the diagnostic codes generated by your car when a problem is detected. There are also some scanners that are listed as ‘OBD2 scanners’.
  • Post-1996 car: Vehicles that are manufactured after 1996 need to have the OBD-II port and diagnostic system to work with the car diagnostic tool. If your car was made before 1996, the issue may have to be diagnosed in the old-fashioned way, which is cracking the hood open or taking the car to a professional mechanic.

Preparation of using a car diagnostic tool

It is very simple and easy to use a car diagnostic tool. All you need to do is plug the device in and turn everything on. To figure out how to work the device, you have to find the right port.

  • First, locate the OBD-II port of your car. It is usually somewhere underneath the dashboard near the steering wheel. However, some cars have their ports somewhere around the centre console or on the passenger side. Read through your car’s user manual for the specific details.
  • Before you plug the diagnostic tool into the OBD-II port, make sure to turn the car engine off.

Useful tips for you

If you are using car diagnostic tools, these tips may be helpful for you –

  • Some diagnostic tools are plugged into the OBD-II port. These tools deliver periodic updates on your car’s health.
  • If you approach a mechanic after scanning your vehicle, bring the codes along so the mechanic can get a head start.
  • Do not reset the check engine light until you find the error trigger. Otherwise, it may come back on later.
