Virgin circuit
When the ignition system is not encrypted, any key
will start the engine but limited to 2000 rpm. The
keys can only be recognised if the control unit has
been programmed properly. The data storage pro-
cedure for a previously not programmed control
unit provides for the recognition of the Master as
the 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 two seconds (lower and upper lim-
its 1 to 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 7 service keys can be programmed
at one time.
It is essential to adhere to the times and the pro-
cedure. If you do not, start again from the begin-
ning. 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 program-
ming deletes the previous one; to add or delete a
key it is therefore necessary to repeat the proce-
dure using all the keys that you intend to keep in
use. If a service key becomes uncoded, the effi-
ciency of the high voltage circuit shielding must be
