What’s NOT included in our free OBD-II scan

  • Diagnostic Troubleshooting: It’s important to understand the difference between a free diagnostic OBD-II scan and an actual troubleshooting diagnostic. The biggest difference is that while a free scan can produce trouble codes and provide clues, a simple scan will not yield a 100% conclusive diagnostic result and cannot be relied upon fully to recommend a repair.

Does your car have warning lights on? If the dashboard on your vehicle is displaying lights such as a check engine light, maintenance required, ABS or traction control, airbag, or other warning light, it’s probably a good time for a free vehicle computer scan. While an OBD-II computer scan may not reveal everything we need to get the full picture of what’s going on under the hood, it’s a great place to start and is a complimentary service we offer that takes only about 15 minutes.

What is an OBD-II Scan?

Your car’s computer system stores diagnostic trouble codes (DTCs) whenever it detects a sensor issue or malfunction. An OBD-II scan uses a specialized tool to read these codes and translate them into clues about what’s wrong under the hood. Any trouble code that occurred historically should be stored in your vehicle’s computer. When we use an OBD-II scan tool to read these codes we can get an idea about what is happening internally.

It’s important to note that an OBD-II scan is not the same thing as an automotive diagnostic. A full diagnostic includes far more than just reading codes from an OBD-II scanner. Diagnostic services include several different techniques that help us get to the bottom of automotive issues and should be performed by a qualified, certified diagnostics technician.
