Imagine this: You’re driving down the road, and suddenly your car starts acting up. The engine light comes on, the dashboard flashes strange warnings, and your car starts to lose power. You’re stranded on the side of the road, wondering what to do next.
This is a scenario that many drivers face. It’s frustrating, expensive, and can be downright scary. But it doesn’t have to be. With online car diagnostics, you can get a better understanding of what’s wrong with your car without having to take it to a mechanic right away.
What is Online Car Diagnostic?
Online car diagnostics is the process of using a specialized software to connect to your car’s computer system and retrieve diagnostic data. This data can then be used to identify and diagnose potential problems. You can perform online car diagnostics yourself with a device called a diagnostic tool.

The use of dealer scanners like Autel Maxifix for European cars allows for comprehensive diagnosis and troubleshooting.
Online Car Diagnostic: From Technical Perspective
From a technical perspective, online car diagnostics rely on the OBD-II (On-Board Diagnostics) system. This system was first introduced in 1996 in the United States and has been adopted by many other countries around the world. The OBD-II system monitors various aspects of your car’s performance, including emissions, engine operation, and transmission. It records diagnostic trouble codes (DTCs) that indicate a potential problem with your car. These DTCs can be read and interpreted by a diagnostic tool.

Online car diagnostics work by connecting a diagnostic tool to your car’s OBD-II port. This port is usually located under the dashboard, near the steering wheel. Once connected, the diagnostic tool can communicate with your car’s computer system and retrieve diagnostic data. This data can then be displayed on the diagnostic tool’s screen, allowing you to identify potential problems.
Some popular diagnostic tools include:
- Autel Maxifix: This is a powerful diagnostic tool for professional mechanics and DIY enthusiasts.
