Car diagnostics can be a costly venture, especially if you’re frequently visiting dealers or mechanics to understand the health of your vehicle. With average dealer diagnostic prices soaring, having an OBD car scanner might just be the money-saving tool you need. In this article, we’ll delve deep into the world of OBD2 scanners and show you how owning one could be a smart investment.
What is an OBD scanner?
An OBD (On-Board Diagnostics) scanner is a specialised device utilised to interface with a car’s on-board computer system. Introduced in the 1990s, the OBD2 (version 2) system was established as a standardised system for car diagnostics across most modern vehicles.
This tool allows mechanics and vehicle owners alike to read and interpret diagnostic trouble codes (DTCs) from the vehicle’s computer, offering insights into potential issues and malfunctions within the vehicle’s engine and other critical systems. In addition to fault diagnosis, some advanced OBD2 scanners offer real-time monitoring and other features.
Available from as little as £20 for a decent model, it is a handy, powerful and relatively cheap tool to have in your toolbox for any car owner, aiding in the comprehensive evaluation and maintenance of your vehicle.
Why do you need an OBD2 scanner?
- Cost-effective: The most significant advantage is the potential savings. With the cost of a diagnostic ranging from around £40 to £120 depending on the garage and make and model of your car. Using an OBD2 scanner a couple of times can recover its cost. Better yet, you may also be able to solve the issue yourself without the need to visit a mechanic, saving you money on expensive hourly charges.
- Quick and easy diagnostics: Instead of waiting for hours or days to get a diagnostic from your mechanic, you can diagnose issues yourself within minutes.
- Empowerment: Understand your car better and make informed decisions about repairs and maintenance.
How do you use an OBD2 scanner?
To read and clear OBD codes yourself, you’ll need an OBD2 scanner and a basic understanding of how to use it.
- The first step is to locate the OBD port in your car. This is typically located under the dashboard, near the steering wheel, but it can vary depending on the make and model of your car (check your manual). Once you’ve found the OBD port, connect the OBD scanner to it (make sure your car’s ignition is off).
- Next, turn on the scanner and/or the car’s ignition and follow the instructions to read the codes. The scanner will display the codes on its screen, along with a description of what the code means. It’s important to note that some codes may be stored temporarily and may not be a permanent issue.
- Once you’ve read the codes, you can clear them using the scanner. Clearing the codes will reset the car’s computer and turn off the check engine light or any illuminated lights in relation to the code, but it will not fix the underlying problem. It’s important to fix the underlying issue before clearing the codes to prevent the issue from reoccurring.
- Look up the relevant codes in your OBD2 manual or search the codes online for further details on what’s causing the related issues.
