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:
- an electronic control unit
- immobilizer aerial
- master key with built-in transponder
- service key with built-in transponder
- diagnosis LED
The diagnosis LED also works as a theft-deterrent blinker. This function is activated every time the key
switch is set to «OFF» or the engine emergency 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 deactivated. 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 regard-
less of the position of the ignition-key switch and/or the instrument panel is not initiated, check if:
- there is battery voltage
- fuses No. 1; 2; 6 and 9 are in working order
- there is power to the control unit as specified below:
2 With the key switch set to OFF:
- if there is battery voltage between terminals 6-26
and terminal 6-chassis ground (fixed power sup-
ply). If there is no voltage, check that fuse 6 and
its cable harness are in working order.
With the key switch in the OFF position:
- if there is battery voltage between terminals 5-26
and terminals 5-chassis ground (fixed power sup-
ply). If there is no voltage, check the key switch
contacts, and that fuses No. 1 and 9 and their ca-
ble harnesses are in working order.
