9.2.2 Un-Coded Electronic Ignition System
When the ignition system is not coded, the engine can be run at a maximum speed of 2,000
rpm. Any attempt to rev up causes the engine to misfire.
To code the system, set the emergency cut-off switch to the «RUN» position and use the
MASTER (brown) and SERVICE (black) keys as follows:
-
Insert the MASTER key; turn the ignition switch to the «ON» position for approximately 2
seconds (strictly between 1 and 3 seconds) and then turn it back to the «OFF» position
-
Insert all the SERVICE keys available in succession, each time turning the ignition switch
to «ON» for 2 seconds
-
Insert the MASTER key again and turn it to «ON» for 2 seconds
Note: The time needed to change keys must not exceed 10 seconds.
Note: A maximum of three SERVICE keys can be programmed within the same coding
session.
It is essential to observe the sequence and time limits as described above. If at any time
during the programming session these are not observed, the procedure will have to be
restarted from the beginning.
Once the control unit has been coded, an unbreakable relation is created between the
control unit and the MASTER key transponder.
This relation allows new SERVICE keys to be
coded in case of loss, replacement, etc. Each
new storing operation cancels the previous
one.
Should the SERVICE keys lose the data stored
in them it is essential to carefully check the
shielding of the high-voltage system:
Standard resistance:
Shielded cap ~5 kO
The use of resistive spark plugs is
recommended (see figure).
