OBD scanners have moved from specialist garage equipment to must-have tools for anyone who wants to understand and maintain their car. If your check engine light illuminates, or you suspect an issue, an OBD scanner is the quickest way to get to the root of the problem. But with so many options available, the question becomes: What Obd Scanner Should I Buy?
Without an OBD reader, a trip to a mechanic to diagnose a fault code can be costly, with labor charges quickly adding up. Investing in your own OBD scanner can save you money and time, allowing you to troubleshoot common car problems from your own garage. Combined with resources like Haynes AutoFix online guides, an OBD scanner empowers you to diagnose and potentially fix many issues yourself using basic tools.
The market offers a vast array of OBD scanners, from basic, budget-friendly models to advanced, feature-rich devices. While they all share the core function of communicating with your car’s computer, understanding the differences is key to choosing the right one for your needs. Let’s explore what an OBD scanner is and what to consider when deciding which one to buy.
Understanding OBD Scanners
An OBD scanner, or On-Board Diagnostics scanner, is a device that plugs into your car’s OBD port. This port, resembling an old SCART connector, has been standard on all petrol cars since 2001 and diesel cars since 2004. Known as OBD2 outside Europe and EOBD in Europe, this 16-pin socket provides access to your vehicle’s diagnostic system and also powers the scanner, eliminating the need for batteries.
At a minimum, any OBD scanner, regardless of price, should be able to:
- Establish communication with your vehicle’s computer system.
- Read diagnostic fault codes that indicate problems within the car.
- Clear fault codes after a repair has been made.
It’s important to note that basic OBD scanners typically focus on engine-related fault codes and may not cover systems like ABS, SRS, or service light resets. For more advanced functions, including resetting service lights and oil life monitors, resources like Haynes AutoFix provide step-by-step guidance to complement your OBD scanner.
