DIESEL EQUIPMENT
General
13
The use of electronic injection in Diesel engines has allowed the operational power of these engines to be
optimised, thus reducing the emission rate of pollutant gases.
The system consists of a computer, which receives information from:
- the coolant temperature sensor,
- the air temperature sensor,
- the engine speed sensor,
- the vehicle speed sensor,
- the load potentiometer,
- the injection start sensor, which forms part of the injector of cylinder n° 3 (injector with sensor).
It controls :
- the injection pump :
• the altimetric corrector (F8Q 630) via a relay
• the advance solenoid valve.
- the cold engine starting system (heater plugs and pre-postheating unit),
- the exhaust gas recycling system (EGR),
- the diesel injection fault warning light,
- the preheating warning light,
- the solenoid valve controlling the fast idle speed LDA,
- the relay controlling the power assisted steering electric pump assembly (for vehicles with air conditio-
ning), the pump assembly is supplied once the engine speed exceeds 650 rpm.
It carries out a self diagnosis procedure which may be visualised through the
XR25.
SPECIAL FEATURES
On the injection pump it is possible to replace:
- the load potentiometer,
- the advance solenoid valve,
- the altimetric corrector,
- the electrical solenoid.

PROGRAMMING THE FULL LOAD POSITION
Switch the ignition off.
Replace the computer.
Carry out the programming of the full load position; in order to do this :
Switch the ignition on.
Connect the
XR25.
Set the selector to S8.
Enter code
Enter code
When the display flashes "PF", press the accelerator pedal down as far as it will go.
The programming is complete when
the screen displays the following
wording: D

G31*
Bargraph N.12 on the right hand side should now be extinguished.
Switch the ignition off.
DPCN LUCAS injection computers are configured before sale to "with air conditioning". If the vehicle is not
fitted with an air conditioning system, use command G50*4* on the
XR25 to carry out the "no air conditio-
ning " programming.
DPCN LUCAS "injection computers are configured before sale to "with power assisted steering " (power as-
sisted steering with pump assembly). If the vehicle is not fitted with a power assisted steering pump as-
sembly, use command G50*9* on the
XR25 to carry out the "no power assisted steering pump assembly"
programming.then

COMPUTER CONFIGURATION IN RELATION TO AIR CONDITIONING.
For vehicles equipped with air conditioning , enter G50*3* on the XR25
For vehicles without air conditioning , enter G50*4* on the XR25 .
COMPUTER CONFIGURATION IN RELATION TO THE PAS (POWER ASSISTED STEERING PUMP ASSEMBLY)
The vehicle may have two types of PAS assembly :
-a
PAS assembly including a high pressure pump driven by a belt. In this case, the computer must be
configured without PAS : enter G50*9* on the
XR25,
-a
PAS assembly with a pump assembly which is driven electrically and controlled by the injection compu-
ter. ( this type of
PAS is fitted in all vehicles which are also equipped with AC). In this case, the computer
must be configured with PAS : enter G50*8* on the XR25.
IMPORTANT : according to the above explanations, only two types of combination are possible for the illumi-
nation of bargraphs 18 and 19.
