This screen will appear when VCDS is attempting to establish communications with a Control Module.
Comm Status
Shows the status of the current communications session. Once communications have been established:
Controller Info
Once the communications session has been established, all of the Control Module's "Identification" data is presented here.
Basic Functions
This grouping of "Safe" functions are used to read various data from the Control Module without making any changes.
Advanced Functions
These functions are capable of making various changes to the Control Module.
You should refer to the Factory Repair Manual for your particular car (or to other documented procedures) before "playing" with these functions.
It is completely possible to render your vehicle inoperable or damage components if you make changes in this section without the correct information and training.
You can click on each of the buttons in this on-line Demo for more information on the individual functions.
VCDS checks which functions are supported by each control module and enables the buttons for supported functions only. It is normal for some buttons to be grayed out on some control modules. This is an indication that the control module in question doesn't support those functions. You can click on each of the buttons in this on-line Demo for more information on the individual functions.
Use [Close Controller, Go Back] to properly close the communications session and return to the Select Control Module screen.
