first key to be stored to memory: this becomes particularly important because it is the only key that
enables the control unit to be wiped clean and reprogrammed for the memorisation of the service keys.
The Master and service keys must be used to code the system as follows:
- Insert the Master key, turn it to « ON » and keep this position for 2 seconds (limit values 1-3 seconds).
- Insert the service key and turn it to « ON » for 2 seconds.
- If you have copies of the key, repeat the operation with each key.
- Insert the Master key again and turn it to « ON » for 2 seconds.
The maximum time to change keys is 10 seconds.
A maximum of 5 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; to add or delete a key it is therefore
necessary to repeat the procedure using all the keys that you intend to keep in use. If a service key
becomes uncoded, the efficiency of the high voltage circuit shielding must be thoroughly inspected. In
any case it is advisable to use resistor spark plugs.

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:

which the LED remains off permanently. The keys
