The control unit is fitted with a self-diagnosis sys-
tem connected to a warning light on the instrument
panel.
Failures are detected and restored by the diagnostic tester.
In any case, when the fault is no longer present, data storage is automatically wiped clean after 16
cycles of use (cold starting, running at regular engine temperature, stop).
The diagnostic tester is also required for adjusting idle speed carburetion.

The MIU injection-ignition system carries out
checks on the rpm indicator and the radiator cool-
ing electric fan.
The MIU control unit power supply is further controlled by the emergency switch to further enhance
vehicle safety.
Precautions
1. Before fixing any part of the injection system, check to see whether there are any faults. Check for
faults before disconnecting the battery.
2. The fuel supply system is pressurised at 250 kPa (2.5 BAR). Before disconnecting the fast-release
fitting of a fuel supply pipe, check that there are no naked flames. Do not smoke. Act with caution to
prevent spraying fuel in your eyes.
3. When fixing electric components, operate with battery connected only when strictly required.
4. When checking functions, make sure that the battery voltage is over 12V.
5. Before attempting to start-up, check to make sure there is at least 2 litres of fuel in the tank. Failure
to observe this procedure can damage the fuel pump.
