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 procedure for a previously un-
programmed control unit provides for the recogni-
tion of the red key (master key) 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 reprogram-
med 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 blue key and set to «ON» for 2 seconds.
- If you have copies of the key, repeat the operation
with each key.
