Security Access Screen

Corresponds to VAG 1551/2 Function 16, (KWP-2000 only)
The Security Access Function must be used on some
(but not all) KWP-2000/CAN/UDS Control Modules before you can Recode or change Adaptation
values. On others, it "enables" certain features like cruise control.
Valid Login codes can be found in the Factory Repair Manual for your
car.
Balloons:
VCDS can show Security Access
"charts" when appropriate information is available in a Label File for
the control module in question. The balloon will appear when the mouse
cursor is hovered over the Enter security access key field.
For certain
immobilizer functions, you can select the largely obsolete [Use 7-digit
PIN/SKC] button to enter a 7-digit Secret Key Code as
explained on this page.
The Option field is
only to be used if you are given specific instructions from Ross-Tech.
Use the
[Do It!] button to save the
Login and return to the Open Controller Screen.
Use the
[Cancel] button to cancel
the Login and return to the Open Controller Screen.
