Injection warning light

OPERATING PRINCIPLE OF THE DIESEL INJECTION WARNING LIGHT ON THE INSTRUMENT PANEL
On switching on the ignition, the diesel injection fault warning light is illuminated. It extinguishes as the en-
gine begins to run.
•Fault in a component of the injection assembly
Faults in the following components may cause the warning light to illuminate :
- injector with sensor
- advance solenoid valve,
- engine speed sensor ,
- load lever potentiometer,
- pre-postheating (according to version).

DIESEL EQUIPMENT
Fast idle speed control
13
- if the engine speed falls to 650 rpm and the
vehicle speed is lower than 15 mph (25 km/h)
(engine start improvement programming).
The fast idle speed is cut off once the speed
becomes > 850 rpm
NOTE :
- Fast idle speed operational :
• solenoid valve not operated,
• cable loose, and not tensioned.
- Nominal idle sped :
• solenoid valve operated
• cable tensioned
SPECIAL FEATURES : once the AC has been
selected on the instrument panel, the fast idle
speed function is activated. The fast idle speed function is controlled by the
computer via a solenoid valve operating the dia-
phragm (versions with or without air conditio-
ning).
The fast idle speed control becomes operational :
- if, on switching on the ignition, the coolant
temperature is below 10°C,

OPERATION - FAULT FINDING
These vehicles are equipped with alternators with
internal ventilation and integral regulator, also
with a warning light on the instrument panel
which has the following functions :
- when the ignition is switched on, the light illu-
minates
- when the engine is started the light extin-
guishes,
- if the light illuminates whilst the engine is
running there is a "charging "fault.
LOOKING FOR FAULTS
The warning light does not illuminate when the
ignition is switched on.
Check:
- all electrical connections are good.
- the bulb has not blown. (Earth the circuit and
the bulb should illuminate).
The warning light illuminates when the engine is
running.
This indicates a charging fault which could be
caused by :
- the alternator drive belt being broken or the
charging wiring being cut,
- internal alternator damage (rotor, stator,
diodes or brush),
- a regulator fault,
- excess voltage.The customer complains of a lack of charge and
the warning light is operating correctly.
If the regulated voltage is less than 13.5 V, check
the alternator. The fault could be caused by :
- a diode which has been damaged,
- a phase which is cut,
- contaminated or worn tracks.
Checking the voltage
Connect a voltmeter across the battery terminals
and read the battery voltage.
Start the engine and increase the engine speed
until the needle registers a stable regulated
voltage.
This voltage should be between 13.5 V and 14.8 V.
Connect as many consumers as possible, the
regulated voltage should be between 13.5 V and
14.8 V.
IMPORTANT: if arc welding work is to be carried
out on the vehicle, the battery and regulator
must be disconnected.

Coolant temperature management
244Injection coolant temperature sensor and
coolant temperature indication on
instrument panel.
3 track sensor, of which two tracks are
allocated to the injection coolant
temperature information, and one to the
indication of the coolant temperature on
the instrument panel.
259Warning coolant temperature switch for
instrument panel.
Operating principle
Sensor 244 allows :
- the coolant temperature to be shown on the
instrument panel,
- the injection computer to receive constant in-
formation on the engine coolant temperature
.
The injection computer, depending on the co-
olant temperature, controls :
- the injection system,
- the cooling fan assembly.
The engine cooling fan assembly is controlled
at fast speed (both slow and fast speeds are
controlled by the air conditioning system) if
the temperature is greater than 99°C. If the
temperature falls below 96°C, it cuts off
automatically ( if a check has to be carried out,
ensure that the air conditioning is not opera-
tional).

PRINCIPLE FOR ILLUMINATION OF INJECTION FAULT WARNING LIGHT ON INSTRUMENT PANEL
• Vehicles not equipped with the immobiliser function:
When the ignition is switched on, the warning light illuminates constantly for 3 seconds , then extin-
guishes.
• Vehicles with immobiliser function deactivated:
When the ignition is switched on, the injection warning light illuminates constantly for 3 seconds and
then extinguishes.
When the doors are unlocked, the red immobiliser light, which was previously flashing, extin-
guishes.When ignition is switched on, it illuminates for 3 seconds , then extinguishes.
• Vehicles with immobiliser function activated:
When the ignition is switched on, the computer does not recognise the code, and stops the engine from
starting. The injection warning light remains illuminated for 3 seconds and then extinguishes.
Before the ignition is switched on, the red immobiliser light flashes. On switching the ignition on, it
flashes more rapidly.
If a fault is detected in the immobiliser system whilst the engine is running, the injection warning light
flashes in the engine speed range between idle speed and 1 500 rpm approximately .
• Fault in a component of the injection system
The warning light is illuminated if a fault has been detected in:
- the pressure sensor,
- the vehicle speed,
- the throttle potentiometer,
- the idle speed regulation stepping motor.
