2.3 Manual Configuration File Creation

If VCDS still reports “No Config File Found” after the test, you may need to manually create the configuration file.

1. Locate the VCDS Installation Folder: This is typically C:Ross-TechVCDS.
2. Create a New Text File: In the VCDS installation folder, create a new text file named VCDS.CFG.
3. Edit the File: Open VCDS.CFG with a text editor like Notepad and add the following lines:

[Options]
Port=USB
Debug=0
BlkInt=55
CharInt2K=6
KP2Time=25
CANTimeout=0
WSC=00000
VZImporter=000
EquipmentNo=00000
