System programming

Two keys are supplied with the vehicle:
- Master key (red) with removable transponder
- Service key (black) with fixed transponder
To codify the system the master key and service key must be used as follows:
- Insert the master key, set to "ON" and keep in this position for 2 seconds (limited values 1-3 seconds).
- Insert the black key and set to "ON" for 2 seconds.
- If duplicate keys are available, repeat the operation with each key.
- Insert the master key again and set to "ON" for 2 seconds.
The maximum amount of time available for changing from one key to the next is 10 seconds.
Up to 7 service keys (black) are accepted in the same memorization process.
The correct timing of the procedure is indispensable; if incorrect, repeat all from the beginning.
Once the system programming has been carried out, an inseparable link is created between the master key
transponder and the decoder and control unit.
Maintaining this link, it is possible to proceed with programming of new service keys resulting from loss, replacement,
etc.
Every new programming procedure cancels the previous one, so to add or eliminate a key it is indispensable that
the procedure be repeated with all the service keys to be used.
NOTE: Accidental loss of the service key programming may derive from general disturbances of the ignition system.
In this case proceed with the H.V. line screening controls.
In any event it is recommended that resistive spark plugs be used.
