Immobiliser circuit
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
MP3 400 i.e. Injection
INJEC - 27
