Security code

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.

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 immobilizer control unit
and ECM (Engine Control Module; Gas Engine only).

New control units are not programmed with a security 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 (e.g. warranty cases), always enclose 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.

1.  Entering a code

If the Tech 2 display requests the

•

security code

•

mechanical key number

•

Vehicle Identification No.

to 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.

With 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.

3.  Transponder

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 proper organization name such as Parts and accessory department" as previously by providing the
mechanical key number.

The mechanical key number is provided on the car pass.

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 to
5 transponder keys can be provided by 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 number
in the car pass is to be changed as well.
