Remove the protective base from the connector.

Virgin circuit
When the ignition system is not codified, any key
can operate the engine but it is limited to 2,000
rpm. The keys can only be recognised if the control
unit has been programmed properly. The memo-
risation procedure of a new control unit provides
for the recognition of the MASTER as the first key
to be saved: 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. To encode the
system it is necessary to use the MASTER key
and the service keys as described below:
- Insert the MASTER key, switch to «ON» and
keep this position for 2 seconds (limit values 1-3
seconds).
- Insert the service key switching to ««ON» for 2
seconds.
- If you have copies of the key, repeat the operation
with each key.
