IMMOBILIZER SYSTEM (C24SE, 4JA1-T) 11A-17
lmportant information on Programming
Security code
The security code protects the immobilizer 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 immobilize
r
control unit and Engine Control Module (ECM).
New control units are not programmed with a securit
y
code.
If the control units are replaced, the security code
entered in the car pass, transponder lD, etc.
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 immobilizer can be reused
in a different car by initializing the immobilizer. After that
you can program the security code again. For initializing
command you need the current security code.
If the immobilizer 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
• mechanical key number
• Vehicle Identification No.
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 o
f
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.
Transponder (Key)

•
••
•
If a transponder key is lost:
If a transponder key is lost, all transponder keys in the
immobilizer control system must be erased.
Transponder keys can be ordered via the "Your prope
r
organization name such as part and accessory
department" as previously by providing the mechanical
key number.
The mechanical key number is provided on the car pass
card.
Thereafter, existing and new transponder keys are
programmed consecutively using Tech-2. The vehicle
can then no longer be started using lost key.
•
••
•
5 transponder keys can be provided:
Each transponder has different Identifications. If a
customer wants more than 2 transponder keys,
maximum 5 transponder keys can be provided b
y
additional programming by Tech-2.
•
••
•
lf a new ignition key with different mechanical key
number needs to be installed:
If installation of an ignition lock with a different
mechanism key number is necessary (an ignition lock
which belongs to the mechanical key number has to be
ordered first), all transponder keys must first be erased
and the two transponder keys which belong to the
ignition lock that is now installed must be programmed.
The new mechanical key number must be programmed
now into the immobilizer. The mechanical key numbe
r
in the car pass is to be changed as well.
Important:
After successful programming, the engine control can
only be used for vehicles with immobilizer and
transponder.
Faults that occur in connection with the immobilize
r
control unit are recognized by the engine control unit
and as long as "IMMOBILOZER" is not programmed,
are indicated by a flashing of the check engine lamp.
If the immobilizer and engine control unit are replaced
at the same time, the immobilizer control unit must be
programmed first before the "IMMOBILIZER" function in
the engine control unit can be activated.
