11B-26 ANTITHEFT SYSTEM

lmportant information on Programming
Security code
The security code protects the antitheft control unit
against unauthorized programming and data access
from Tech-2. The security code consists of a 4 digit
code number and is programmed into the antitheft
Control Module (ACU).
New control units are not programmed with a security
code.
If the control units are replaced, the security code
entered in the transmitter (into remote key).
Must be programmed into the new control unit with
Tech-2.
The security code can only be programmed with Tech-2
once and must therefore be performed with great care.
Once programmed, the security code cannot be
overwritten. An already used antitheft can be reused in
a different car by initializing the antitheft. After that you
can program the security code again. For initializing
command you need the current security code.
If the antitheft control unit is returned, always enclosed
the security code that is allocated to that control unit. If
this is not done, we can not process the case and the
warranty will not be recognized.

Entering a code
If the Tech-2 display requests that the
• security code
• Vehicle Identification No.
• Country code (Select 213 Germany in all items)
be entered, process as follows;
To input a digit you need to use the up and down
buttons of the Tech-2. By using the numeric buttons the
according digit will be displayed at the current position
and the cursor will move to the next position.
For letters you need to use the up and down buttons of
the Tech-2. The up and down key might be used for
digits as well. By using the up and down buttons the
displayed digit or letter will be increased or decreased.
To move to the next position you need to use the move-
to-right-button.
W ith the two buttons, move-to-right and move-to-left
you can select the position of number you want to
change.
This will allow you to correct a wrong number.
After the number is completed you need to press the
Enter button to accept the number. Correction is now no
longer possible.
Use the OKAY soft key to program the number and the
NOT OKAY soft key to abort the programming.
