The market is flooded with scanners for car codes, offering a wide range of features and prices. While they vary in bells and whistles, their core function remains the same.

We’ve explored the benefits and features to help you understand why this tool is indispensable.
Understanding the Power of a Scanner for Car Codes
Traditionally, a scanner for car codes – also known as an OBD reader or diagnostic scanner – was a dedicated handheld computer. It plugs into your car’s computer system to pull up diagnostic trouble codes (DTCs), among other data points. Prices can range from budget-friendly options around £10 to more advanced professional-grade units costing hundreds. Regardless of price, a reliable scanner for car codes should, at a minimum, be able to:
- Establish communication with your vehicle’s computer system.
- Read and display stored fault codes.
- Clear or erase fault codes after repairs are made.
It’s important to note that while most basic scanners for car codes are excellent for reading and clearing engine fault codes, they typically won’t handle tasks like turning off service lights for systems like ABS or SRS, or resetting oil life monitors. For more in-depth procedures like these, resources like Haynes AutoFix provide step-by-step guidance.

Decoding OBD: How Scanners for Car Codes Connect with Your Car
OBD stands for On-Board Diagnostics. It refers to a standardized port in your vehicle, often resembling an older style TV SCART connector. This OBD port has been a mandatory feature in all petrol passenger cars sold since January 1, 2001, and in diesel cars since 2004. This standardized 16-pin connector is known as OBD2 in regions outside of Europe and EOBD (European On-Board Diagnostics) within Europe, essentially referring to the same standard.
A vehicle’s OBD port, the universal connection point for scanners for car codes, enabling communication with the car’s computer system for diagnostics.
The OBD socket is more than just a data port; it also supplies power. This clever design means that your scanner for car codes doesn’t require its own power source like batteries or a separate power cable, simplifying its use and portability. This direct connection allows the scanner to directly tap into your car’s computer, making it an efficient tool for any car owner wanting to understand and address their vehicle’s issues.
