For anyone keen on maintaining their car at home, an OBD scanner is no longer a luxury, but a necessity. Modern vehicles are complex machines, and when that engine light pops up, an OBD scanner is your first step in understanding what’s wrong.
Are OBD scanners a worthwhile investment? Absolutely. They offer the quickest route to diagnosing car troubles. Without one, you’re looking at a trip to a mechanic just to identify the fault code. Considering that garage labor rates can average around $60-$100 per hour, owning an OBD scanner can save you money from the get-go. Combine an OBD scanner with resources like Haynes AutoFix online guides, and you’re equipped to tackle a wide range of common car faults and electrical problems right in your own garage using basic tools.
The market is flooded with OBD readers, from basic models to advanced, feature-rich devices. While they vary in price and complexity, their core function remains the same. Many OBD scanners are priced less than a single diagnostic visit to a professional mechanic. But with so many options, the question becomes: What Obd Scanner To Buy? Let’s delve into what you need to know.
Understanding OBD Readers
Traditionally, an OBD reader was a dedicated handheld diagnostic tool that plugs into your car to communicate with its computer system. These devices can range from very affordable – around $20 – to professional-grade scanners costing hundreds of dollars. Regardless of the price point, a functional OBD scanner should at least:
- Establish communication with your vehicle’s computer.
- Retrieve diagnostic fault codes.
- Clear or reset fault codes.
It’s important to note that basic OBD scanners typically do not handle tasks like turning off service lights for systems beyond the engine or resetting maintenance monitors for systems like ABS or SRS. For these more advanced resets, resources like Haynes AutoFix can provide step-by-step guidance, often in conjunction with the data you retrieve from your OBD scanner.

The Functionality of OBD Systems
OBD stands for On-Board Diagnostics. It refers to a standardized port in your vehicle, which, to the unfamiliar, might resemble an older style SCART connector. Since January 1, 2001, all petrol passenger cars sold in Europe have been required to have these OBD ports, with diesel cars following suit from 2004. This 16-pin connector is known as OBD2 in most parts of the world and EOBD (European On-Board Diagnostics) in Europe.
The OBD port is not just for communication; it also supplies power. This means your OBD scanner doesn’t need batteries or a separate power cable – it draws the necessary energy directly from your car. This simple connection makes it incredibly user-friendly for quick diagnostics whenever you need them.
An OBD-II port, usually located under the dashboard on the driver’s side of most vehicles.
