The maximum time to change keys is 10 seconds.
A maximum of 7 service keys can be programmed at one time.
It is essential to adhere to the times and the procedure. If you do not, start again from the beginning.
Once the system has been programmed, the master key transponder is strictly matched with the control
unit. With this link established, it is now possible to encode new service keys, in the event of losses,
replacements, etc. Each new programming deletes the previous one so, in order to add or eliminate
keys, you must repeat the procedure using all the keys you intend to keep using. If a service key should
become un-coded, the efficiency of the high voltage circuit shielding must be thoroughly inspected: In
any case it is advisable to use resistive spark plugs.

Diagnostic codes
The immobiliser system is tested each time the ig-
nition-key switch is turned from OFF to ON. During
this diagnosis phase a number of control unit sta-
tuses can be seen and various light codes dis-
played. Regardless of the code transmitted, if at
the end of the diagnosis the led remains off per-
manently, the ignition is enabled. If, however, the
led remains on permanently, it means the ignition
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 per-
manently ON; in this condition, no operations are
possible, including starting of the vehicle.
