- Insert the MASTER key, turn it to "ON" and keep
it in that position for 2 seconds (limit values: 1 ÷ 3
seconds).
- Alternately insert all the available Black keys set-
ting each of them to "ON" for 2 seconds.
- 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 3 (Black) service keys can be pro-
grammed at one time.
Sequence and times must be strictly observed or
it will be necessary to repeat the procedure from
the start. Once the control unit has been program-
med, the control unit is inseparably matched with
the MASTER key transponder.
This matching allows programming further service
keys in case of loss, replacement, etc. Each new
time new data is programmed the previously stor-
ed one is deleted. If a service key should become
un-coded, the efficiency of the high voltage circuit
shielding must be thoroughly inspected: In any
case it is advisable to use resistive spark plugs.

Diagnostic codes
The flash indicating the switching to "ON" can be followed by a phase of programmed failure warnings.
That is, the led is off for 2 seconds, and then diagnosis codes are transmitted with 0.5-second flashes.
After the failure code indication, a steadily on LED signals that ignition is disabled; see the table:

Example with programmed control unit, no transponder and/or malfunctioning aerial.
