In this video I explain how to use one of the most reliable OEM scan tools for KIA & Hyundai Vehicles. This scan tool is called GDS and not only covers all systems diagnostics %100, but also it provides the workshop manuals, wiring diagrams, parts removal guides, fault code diagnosis guide and much more. I explain how to read the fault codes and live data and how to use the actuation test and vehicle s/w management (special function). Then I show you how to find and use the workshop manuals, wiring diagrams, fault code diagnosis guide and part removal.
