The control unit autodiagnostic system checks the signals coming from the sensors and compares them
with the figures allowed:
- signalling faults during starting
- warning light on for 4 seconds indicates test stage
- warning light off after 4 seconds indicates no fault with components that could alter the pollution con
trol standard figures
- warning light on after 4 seconds indicates fault.
- signalling faults during operation
- warning light on indicates fault
- warning light off indicates no fault with components that could alter the pollution control standard fig
ures.
- recovery
- from time to time, the control unit defines the type of recovery according to the components which are
faulty
- the recovery parameters are managed by components which are not faulty.
Control of cylinder balancing during idling
According to the signals coming from the sensors, the injection control unit controls the idle speed torque,
altering the injector operating times.
Control of irregular operation
Depending on the signals coming from the sensors, the injection control unit corrects the amount of fuel
to be injected in order to improve driveability and reduce jerking whilst driving.
The correction is achieved through the fuel pressure regulator and by varying the injector operating times.
Control of electrical balance
According to the battery voltage, the injection control unit alters the idle speed, to guarantee a sufficient
current supply from the alternator in situations where the consumers are absorbing a great deal of power.
The variation in the idle speed is achived by regulating the fuel pressure and altering the injector operat
ing times.
VGT variable geometry turbocharger control (1910 JTD 110 CV)
The injection control unit processes the signal coming from the supercharging sensor, at the various en
gine operating speeds, and determines the quantity of fuel to be injected, acting on the fuel pressure
regulator and the injector opening times.
In addition, through the solenoid valve, the control unit regulates the geometry of the turbine in order to
ensure optimum performance in all operating conditions.
Turbocharger waste gate valve control (1910 JTD 100 CV)
At the various engine operating speeds, the injection control unit processes the signal coming from the
supercharging sensor and determines the amount of fuel to inject, acting on the fuel pressure regulator
and the injector opening times.
In addition, the control unit controls the opening of the turbocharger waste gate valve, via the solenoid
valve, in order to ensure excellent performance in all operating conditions.
Control of throttle closing when engine is switched off
When the engine is switched off (ignition key in OFF position) the injection control unit closes the throt
tle valve located on the air intake duct via the special solenoid valve.
This action makes it possible to limit the tiresome shuddering of the engine whilst it is switching off.

WARNINGS
Anti-theft protection
The radio comes with a theft protection system comprising of a segret 4 digit code.
The protection system makes the rdaio inoperable if it is removed from the facia as a result of a theft. See
the following pages to activate the antitheft device
CODE card
The radio identity document shows the model, serial number and secret code.
The serial number is the same as the number stamped on the set frame
If the set is lost, the CODE card facilitates search investigations and speeds up claim settlement by insurers
due to the ownership document.

A
If the antitheft protection is active and the radio is disconnected from the car battery, the radio is
still protected electronically
It may only be operated again by entering a special code.
Display
If the set is disconnected from the voltage supply, the display figures flash when it is reconnected.
The flashing figures are a reminder that the clock must be reset as described below.
Extended function field (EXP key)
The EXPERT control level allows the user to use a range of functions beginning with the base control yet
without losing an overall view.
Operation with mobile phone (PHONE)
The radio is designed for connection to a mobile phone handsfree system (using the PHONE IN input).
The radio sound is deactivated while the mobile phone is in operation.
PHONE appears on the display.
