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
34
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.

CONNECTION BETWEEN AIR CONDITIONING ASSEMBLY AND INJECTION COMPUTER
The electrical connection :
- from the air conditioning computer to the diesel injection computer consists of one wire. This track only
carries the information that the AC is operating. From this, the diesel injection computer deduces the AC
selection information : track 11,
- from the diesel injection computer to the air conditioning computer consists of one wire. This track
carries all information regarding authorising and preventing operation of the compressor : track 19.
COMPRESSOR OPERATION PROGRAMMING
During certain stages of operation, the diesel injection computer stops the compressor from functioning.
Engine start programming
After the engine has started running, the compressor is prevented from functioning for 3 seconds.
Performance return programming
If the full load position is detected, the AC compressor is prevented from functioning for 8 seconds.
Stalling prevention programming
If the engine speed is lower than 650 rpm., the compressor is automatically cut off. It will only be allowed to
function again if the engine speed exceeds 775 rpm.

CONDITION FOR BLEEDING THE CANISTER ( D7F
engine)
• Coolant temperature greater than+ 15 °C
•Air temperature greater than +10 °C.
• No load position not recognised (if there is a
fault in the throttle potentiometer sensor, the
condition of no load position not recognised is
replaced by an engine speed condition
R > 1500 rpm.).
It is possible to visualise the cyclical opening ratio
for the canister bleed solenoid using the
XR25
and #23. The solenoid is closed if #23 = 0.7 %
CONDITION FOR BLEEDING THE CANISTER (E7J
engine)
During richness regulation
Coolant temperature greater than 50°C.
Air temperature greater than 15°C.
No load position not recognised (if there is a fault
in the throttle potentiometer sensor, the
condition of no load position not recognised is
replaced by an engine speed condition
R > 1500 rpm.).
Outside richness regulation
•Coolant temperature greater than 50°C.
•Air temperature greater than 15°C.
•Full load position recognised (function of
engine speed and manifold pressure).
If there is a fault in the oxygen sensor, bleeding is
permitted outside of no load conditions.
It is possible to visualise the cyclical opening ratio
for the canister bleed solenoid using the
XR25
and #23. The solenoid is closed if #23 = 0.7 %
(minimum value).

CHECKING CANISTER BLEED OPERATION
Incorrect operation of the system may cause the
idle speed to be unstable or the engine to stall.
Check the conformity of the circuit (see
operational diagrams)
Be sure to check that the pipe marked "CAN" on
the solenoid valve is correctly connected to the
canister.
Check the condition of the pipes to the fuel tank.

3Canister
4Fuel tankAt idle speed connect a pressure gauge
(- 3 ; +3 bars) (Mot. 1311-01) to the "CAN" outlet
on the solenoid valve, to check there is no vacuum
(the command value read by the
XR25 for #23 re-
mains minimal X = 0.7 % ). Is there a vacuum ?
YESIgnition off, use a vacuum pump to apply a
vacuum of 500 mbars to the solenoid valve
at (C). This should not vary by more than 10
mbars in 30 seconds.
Does the pressure vary?
YESThe solenoid valve is faulty. Renew it. Air
must be blown into the pipe (A) connecting
the solenoid valve to the canister to remove
any particles of active carbon.
NOThere is an electrical fault. Check the circuit.
NOUnder bleeding conditions (not at idle
speed, engine warm), the vacuum should
increase (the value for #23 on the XR25
should also be seen to increase).
