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:
-
IC= Shows the number of times the
session has been initialized.
If IC increases beyond 1, communications are less than 100% reliable.
-
TE=
Counts transmitter errors within individual packets. TE greater than
0 can indicate unreliable communication.
-
RE=
Counts receive errors
within individual packets. RE greater than 0 can indicate unreliable communication.
-
Protocol indicates whether
the controller speaks
KWP-1281, KWP-2000, CAN,
or UDS.
-
A rotating cursor shows that communication is
active.
Controller Info
Once the communications
session has been established, all of the Control Module’s
"Identification" data is presented here.
-
VAG Number is the VW/Audi
part number for this controller.
All
of the digits, both numbers and letters, make up the part number. In
some cases this number may be different from the number on the sticker
on the module itself, specifically if the module has been reflashed by a
dealer per a service campaign.
-
Component contains more
identification information about the controller and may contain a
version number for the controller's internal firmware.
-
Soft. Coding is the Software
Coding that determines various options for the controller.
Note: Some older
Control Modules are not "codeable" and you may see a Bosch part number
or other information in this field.
-
Shop # identifies the
WorkShopCode ( WSC ) stored in the scan-tool that last Recoded this Control
Module.
-
The Extra fields can show VIN
and Immobilizer information or slave controller part numbers in some
vehicles.
Basic Functions
This grouping of "Safe" functions
are used to read various data from the Control Module.
Advanced Functions
These functions are capable of making
various "programming" 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.
