About OBD: On-Board Diagnostics

What are OBD scanners?

OBD, or On-Board Diagnostics, is essentially your car’s way of communicating with you about its health. An OBD scanner is a tool that lets you tap into this conversation. If you’re curious about where the tech is heading, you might want to check out the rumors about OBD3 and its upcoming features.

What are the different types of OBD scanners?

Bidirectional Scanners: These aren’t your ordinary scanners. They not only receive information but can also talk back to your car, making testing and diagnosis even more thorough. Here are some of the best bidirectional scan tools I tested for 2023.

Bluetooth Scanners: These are modern, wireless, and super convenient. If you’re looking for budget-friendly options, both FIXD and BlueDriver are solid picks. Dive into these top Bluetooth scanner recommendations to see what might work best for you.

I’ve got a light on my dashboard that’s bugging me. Can an OBD help with that?

For sure. Different lights signal various issues. If you’re dealing with the electronic throttle control light, here’s an in-depth explanation and fix. Seeing the SRS light? Here’s what it means and some handy repair tips. And if a wrench icon has got you puzzled, this guide will help you understand what your car is trying to tell you.

My OBD scanner isn’t communicating with my car. What should I do?

Technology can be finicky at times. If your scanner’s giving you the silent treatment, this step-by-step troubleshooting guide should help.

Do all cars have the same OBD port? Even, say, a Tesla?

While most modern cars are equipped with the OBD2 port, electric vehicles, like Tesla, might be a bit different. Here’s a detailed look at what Tesla models have on offer.
