OBD scanners have revolutionized car maintenance for DIY enthusiasts. Being able to decipher those cryptic engine fault codes is no longer exclusive to professional garages. In today’s world, an OBD scanner is as vital to a home mechanic’s toolkit as a wrench set.
Are these diagnostic tools truly worth the investment? Absolutely. Think about it: the moment your car’s check engine light illuminates, the clock starts ticking. Without an OBD reader, your next stop is likely a garage, just to identify the problem. Considering that hourly labor rates at independent garages average around £50, avoiding even one trip pays for many entry-level OBD scanners. Imagine pairing a Streetwize car diagnostic tool with online resources like Haynes AutoFix. Suddenly, diagnosing and tackling common faults and electrical gremlins in your driveway becomes a real possibility, armed with just basic tools.
The market is flooded with OBD readers, from budget-friendly to professional-grade. While features and price tags vary significantly – from under £15 to hundreds – their core function remains the same. The essential capabilities of any reliable OBD reader, including Streetwize models, should include:
- Establishing communication with your vehicle’s computer system.
- Reading and interpreting diagnostic fault codes.
- Clearing fault codes after repairs.
It’s worth noting that many basic OBD scanners may not handle tasks like resetting service lights or managing monitors for systems like ABS and SRS. However, comprehensive guides like Haynes AutoFix can often bridge this gap, guiding you through these processes.

Understanding OBD and How it Works
OBD, short for on-board diagnostics, refers to a standardized port in your car that allows communication with its internal computer. Visually, it might resemble an older style SCART connector. Since January 1, 2001, all petrol passenger cars sold in Europe have been equipped with OBD ports, followed by diesel cars from 2004. This 16-pin connector is internationally recognized as OBD2, and in Europe, it’s often referred to as EOBD.
A clever feature of the OBD socket is that it also supplies power. This eliminates the need for separate power sources like batteries or power cables for your Streetwize or any other OBD scanner. Simply plug it in, and it’s ready to communicate with your car and help you understand what’s going on under the hood.
