Immobiliser
The electronic ignition system is controlled by the
control unit with the integrated Immobilizer sys-
tem. The immobilizer is an antitheft system that
allows the vehicle to be operated only when it is
started with coded keys recognised by the control
unit. The code is integrated in a transponder in the
key block. This allows the driver clear operation
without having to do anything other than just turn-
ing the key. The Immobiliser system consists of the
following components:
- electronic control unit
- immobilizer aerial
- Master key with incorporated transponder (red
key)
- service key with incorporated transponder (black
key)
- HV coil
- Diagnosis LED
The diagnosis LED also works as a blinking light
to deter theft. This function is activated every time
the key switch is set to «OFF» or the engine emer-
gency cut-off switch is set to «OFF». It remains
activated for 48 hours in order not to affect the
battery charge. When the ignition switch is turned
to «ON» the deterring blinker function is deactiva-
ted. Subsequently, a flash confirms the switching
to «ON».The duration of the flash depends on the
programming of the electronic control unit. If the
LED is off regardless of the position of the ignition-
key switch and/or the instrument panel is not initi-
ated, check if:
•
there is battery voltage
•
fuses 1-7-10-11 are in working order
•
there is power to the control unit as
specified below:
