Diagnostic codes
The Immobilizer system is tested each time the ig-
nition key is turned from «OFF» to «ON». During
this diagnosis phase a number of control unit sta-
tuses can be identified and various light codes
displayed. Regardless of the code transmitted, if
at the end of the diagnosis the LED remains off
permanently, the ignition is enabled. If, however,
the LED remains on permanently, it means the ig-
nition is inhibited:
1. Previously unused control unit - key inser-
ted : a single 2 second flash is displayed, after
which the LED remains off permanently. The keys
can be stored to memory, the vehicle can be star-
ted but with a limitation imposed on the number of
revs.
2. Previously unused control unit - transpond-
er absent or cannot be used : the LED is on
permanently. In this condition no operations are
possible including the start up of the vehicle.
3 . Programmed control unit - the service key in
(normal condition of use) : a single 0.7-second
flash is displayed, after which the LED remains off
steadily. The engine can be started.
4 . Programmed control unit - Master key in : a
0.7-sec flash is displayed followed by the LED re-
maining off for 2 secs.
