Understanding VAG COM Diagnostic Cables
What is VAG COM?
VAG COM, now known as VCDS (VAGCOM Diagnostic System), is a diagnostic tool developed by Ross-Tech that interfaces with your vehicle’s OBDII system. It allows you to diagnose and modify various functions of your car. The VAG COM system is utilized for nearly all VAG vehicles built from 1990 to the present.
How Does It Work?
The VAG COM diagnostic cable connects to your vehicle’s OBD port and interfaces with a Windows-based software program. The software communicates with the car’s ECU (Engine Control Unit), allowing you to read diagnostic trouble codes (DTCs), perform adaptations, and access live data. This capability is invaluable for troubleshooting issues and making informed decisions about repairs.
