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 (limit values 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.
- 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 (blue) can be pro-
grammed 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, master
key transponder, decoder and control unit are
strictly matched.
With this link established, it is now possible to en-
code new service keys, in the event of losses,
replacements, etc.
Each new programming deletes the previous one
so, in order to add or eliminate keys, you must re-
peat the procedure using all the keys you intend to
keep using.
If a service key becomes uncoded, the efficiency
of the high voltage circuit shielding must be thor-
oughly inspected: In any case it is advisable to use
resistive spark plugs.
