Affected terminals: -
Possible trouble code: -
Note:
When a new immobiliser
control unit is installed in a vehicle, the security code, the engine
type, the mechanical key number and the vehicle identification number
(chassis number) are programmed consecutively. If a new engine control unit
is installed in a vehicle, the security code does not have to be programmed,
as it is stored in the immobiliser control unit, not in the engine control
unit. The other data (engine type, mechanical key number and vehicle
identification number) can then be programmed individually (see sections
4.7.4 to 4.7.6). For the valid security code, engine number, mechanical key
number and vehicle identification number, consult the car pass issued to the
customer on delivery of the vehicle.
Important:
The security code consists
of a four character digit combination and can only be programmed once.
Thereafter, it can be neither altered nor erased; for this reason, proceed
with great care when programming.
Ignition OFF
Press key F7 in the system
main menu, select IMMOBILISER using
the arrow keys and confirm with YES. Follow the instructions on the TECH 1
display.
Note:
The arrow keys can now be used
to program the security code, by selecting the desired digit
and confirming with YES. TECH 1 automatically jumps to the next digit after
actuation. The cursor for the next digit being programmed flashes on the TECH
1 display. Once all four security code digits have been programmed, input is
confirmed with ENTER. The security code can now no longer be altered.
Important:
The security code is always
entered consecutively twice. TECH 1 then compares the entered codes and
evaluates the results.
If SECURITY CODE MISMATCH! appears on the display, a fault
has occurred during the programming of the security code (TECH 1 has
determined a fault on comparison of the two inputs).
Input of the security code
must be repeated.
