3-Flash Diagnostic Code
If the 3-flash diagnostic code is displayed, check if the anomaly persists even after inserting
the MASTER key into the ignition switch.
If the malfunction disappears when the MASTER key is used, proceed to a new coding of the
SERVICE (black) keys.
If the anomaly persists, then the MASTER key and the control unit are not matched. In that
case, replace the control unit and proceed to code the keys.
The immobilizer system is in working order when, after turning the ignition switch to «ON»,
a single 0.7-second flash is emitted (see graph below).
In that case, ignition is possible.
Example

(standard operating conditions)
1 = LED on
2 = LED off
3 = No flashing
4 = LED remains off

Ignition System
Once the immobilizer system has been enabled, it is possible to obtain a spark at the plug
through the H.T. coil and the signals coming from the pick-up.
The basic power supply is represented by the battery. The system is calibrated in such a
way that any voltage drops in the battery are detected by the starting system and is
therefore virtually harmless to the ignition system.
The pick-up is connected to the control unit by a single wire. As a result, the pick-up ground
is connected to the control unit through the frame and the earth wire from the engine.
To avoid hampering the ignition system during the starting process, it is important that the
engine/frame ground connection is as efficient as possible.
