VAG-COM
Open Controller / Select Function Screen

This screen will appear when VAG-COM is
attempting to establish communications with 
a Control Module.

Comm Status
Shows the status of the current communications
session.  Once communications is established,
IC= shows the number of times the session has
been initialized. If IC increases beyond 1, 
communications are less than 100% reliable.
Blk= is a counter that shows the current
protocol block number.  You can ignore this;
it should constantly increment and "wrap"
at 255.  If it stops, an communications error
has been detected.  Just wait a few seconds,
the session should automatically reinitialize.
TE= and RE= are counters for errors within 
individual packets. Protocol indicates whether
the controller speaks KWP-1281 or KWP-2000.

Controller Info
Once the the communications session has been established,
all of the Control Modules "Identification" data is presented here.
VAG Number is the VW/Audi part number for this controller.
Component usually tells what it is, and may contain a 
version number for the controller's internal firmware.
Soft. Coding is the Software Coding and determines 
various options for the controller.
Shop # identifies the WorkShopCode stored in the 
scan-tool that last Recoded this Control Module.
Note:  Some older Control Modules are not "codeable"
and you may see a Bosch part number or other information
in theses fields. The Extra fields can store VIN and Immobilizer
information in some vehicles.

Basic Functions
This grouping of "Safe" functions are used to read various
data from the Control Module.  Click on each of the buttons 
for more information regarding the individual functions.
Grayed out buttons are functions that have not yet been
implemented.

Advanced Functions
These functions are capable of making various 
"programming" changes to the Control Module.  
You should refer to the  Work Shop  Manual 
for your particular car (or some other documented 
procedure) before "playing" with these 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.
