The control unit is provided with a self-diagnosis
system connected to an indicator light in the in-
strument panel.
Failures are detected and restored by the diag-
nostic tester.
In any case, when the fault is no longer present,
the data storage is wiped clean after 16 cycles of
use (cold start, running at normal engine temper-
ature, stop).
The diagnostic tester is also required for adjusting
the idle mixture.

Scooter diagnosis and tester
The MIU injection-ignition system carries out
checks on the rpm counter and the electric fan for
radiator cooling.
The MIU control unit has a decoder for the anti-
theft immobiliser.
The MIU control unit is connected to a diagnostic
LED on the instrument panel, that also carries out
the deterrent flashing functions.
The MIU control unit power supply is furthermore controlled by the emergency switch; that is to provide
further safety for the scooter.
Precautions
1. Before fixing any part of the injection system, check to see if there are any registered faults. Do not
disconnect the battery before checking for faults.
2. The feeding system is pressurised at 300 kPa (3 BAR). Before disconnecting the fast-release fitting
of the power supply pipe, check that there are no naked flames. Do not smoke. Act with caution to
prevent spraying in the eyes.
3. When fixing electric components, operate with battery connected only when actually required.
4. When functional checks are performed, check that the battery voltage is more than 12V.
