For anyone keen on maintaining their car at home, an OBD scanner is no longer a luxury—it’s a necessity. These devices are your quickest route to understanding what’s ailing your vehicle. Imagine facing a dashboard warning light. Without an OBD reader, a trip to the local garage becomes inevitable just to diagnose the fault. Considering that garage labor rates can quickly become expensive, investing in an OBD scanner is a smart move for any car owner looking to save money and time. When you combine an OBD fault code reader with resources like Haynes AutoFix, you empower yourself to diagnose and fix a wide range of common car problems and electrical issues right in your driveway using basic tools.
The market offers a plethora of OBD readers, from budget-friendly to professional-grade models. While the features and prices vary significantly, their core function remains the same: to communicate with your car’s computer and help you understand what’s wrong. But with so many options available, the question naturally arises: Which Obd Scanner Should I Buy?
Understanding OBD Readers
An OBD reader, in its most traditional form, is a handheld diagnostic tool that plugs into your car and interprets the data from its onboard computer. These tools can range in price from very affordable to quite expensive, depending on their capabilities. Regardless of the price point, a functional OBD scanner should, at a minimum, be able to:
- Establish communication with the vehicle’s computer system.
- Read and display diagnostic fault codes.
- Clear or reset fault codes after repairs.
It’s important to note that while basic OBD scanners are excellent for reading and clearing engine fault codes, they typically do not handle more advanced functions like turning off service lights for systems like ABS or SRS, or resetting oil life monitors. For these more complex tasks, resources like Haynes AutoFix can provide step-by-step guidance.

How OBD Systems Work
OBD stands for On-Board Diagnostics. The OBD system is accessed through a 16-pin port, often likened in appearance to an old SCART connector, that has been a standard feature in all petrol cars sold in Europe since January 1, 2001, and in diesel cars since 2004. This port is universally known as OBD2 outside of Europe and EOBD within Europe.
The OBD port is not just for data transfer; it also supplies power to the connected device. This means your OBD scanner doesn’t need batteries or a separate power cable, making it convenient and easy to use.
