Checks and inspections

This section is devoted to the checks on the electrical system components.
Immobiliser
The electronic ignition system is controlled by the control unit with the integrated Immobilizer system.
The immobilizer is an anti-theft 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 turning the key. The
Immobilizer 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 theft-deterrent blinker. This function is activated every time the
ignition switch is turned to the "OFF" position, or the emergency stop switch is turned to the "OFF"
position. It remains activated for 48 hours in order not to affect the battery charge. When the ignition
switch is turned to the "ON" position, the theft-deterrent blinker function is deactivated. Subsequently,
a flash confirms the switching to the "ON" status. 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 initiated, check if:
•
there is battery voltage
•
fuses 1,5,7,8 are in working order
•
there is power to the control unit as specified below:
Remove the connector support bracket shown in the photograph and disconnect the connector from
the control unit. Check the following conditions:
With the key switch set to OFF:
•
if there is battery voltage between ter-
minals 6-26 and terminal 6-chassis
ground (fixed power supply). If there is
no voltage check that fuse 1 and its ca-
ble are in working order.
