INJECTION
Idle speed correction
17
CONNECTION BETWEEN THE POWER ASSISTED STEERING PRESSOSTAT AND THE INJECTION COMPUTER
The injection computer receives information from the power assisted steering pressostat . This varies
depending on the pressure present in the hydraulic circuit. The higher the pressure, , the more energy is
absorbed by the power assisted steering pump.
To compensate for this energy absorption, the injection computer increases the opening ratio of the idle
speed regulation stepping motor.
The information is received on track 13 of the injection computer. If the pressostat is closed , the computer
receives an earth . The idle speed is adjusted to 800 rpm for the D7F engine and 850 rpm for the E7J
engine .
IDLE SPEED CORRECTION DEPENDING ON THE BATTERY VOLTAGE
The objective of this correction is to compensate for the drop in voltage, due to consumer operation when
the battery is poorly charged To correct this, the idle speed is increased, allowing the alternator to rotate
faster and consequently increase the charging voltage.
The lower the voltage, the greater the degree of correction. Correction of the engine speed is therefore
variable. It begins when the voltage drops to below 12.7 Volts. Correction begins at the nominal engine
speed and may reach a maximum of 880 rpm for the D7F engine and 930 rpm for the
E7J engine .
IDLE SPEED CORRECTION DEPENDING ON AIR CONDITIONING OPERATION
The injection computer increases the idle speed to 850 rpm. for the D7F engine and 880 rpm . for the E7J
engine , provided it receives the fast idle speed information from the air conditioning computer.

INJECTION
Adaptive idle speed correction
17
PRINCIPLE
Under normal warm engine operating conditions , the R.C.O. idle speed value at #12 varies between a
high value and a low value, until the nominal idle speed is obtained .
It is possible that during variations in the operation of the vehicle (running in, engine wear..), that the
R.C.O. idle speed value could become close to the highest or lowest values.
The adaptive correction (#21) of the
R.C.O. idle speed (#12) allows the slow variations in the engine air re-
quirement to be corrected, so that the
R.C.O. (#12) is recentred to an average nominal value.
This correction only becomes effective if the coolant temperature is higher than 75°C, 20 seconds after
starting the engine and if the nominal idle speed regulation phase has been reached.

- minimum : - 4.3 %
- maximum :+3.9 %Limit value:
- minimum : - 2.4 %
- maximum :+6.2 %
INTERPRETATION OF THE GATE VALUES
In the case of excess air (air leak or throttle stop incorrectly adjusted ..) the idle speed increases, and the
R.C.O.idle speed value at #12 decreases , in order to return to the nominal idle speed; the value of the
R.C.O.idle speed adaptive correction at #21 decreases to re-centre the R.C.O. idle speed at #12.
In the case of a lack of air (contamination, etc.), the process is inverted : the
R.C.O. idle speed at #12 in-
creases and the adaptive correction at #21 also increases, in order to re-centre the #12 to an average nomi-
nal value.
IMPORTANT : It is vital, after erasing the memory from the computer (disconnecting the battery), to let the
engine run at idle speed before returning the vehicle to the customer, so that the adaptive correction can be
correctly reset.

CLEANING
It is very important not to scratch the gasket faces
of all aluminium components.
Use the product Décapjoint to dissolve the part
of the gasket which remains attached.
Apply the product to the part to be cleaned, wait
approximately 10 minutes, then remove it using a
wooden spatula.
The wearing of gloves is recommended during
this operation.

DRAINING THE FUEL TANK ( Diesel version)
Since Diesel versions are not fitted with an electri-
cal fuel pump, a manual pump must be used to
drain the tank.
For example, the
INTAIRCO pneumatic siphoning
pump is suitable for this operation (see
EQUIPMENT catalogue),
Shunt tracks 3 and 5 and let the fuel flow until it
runs out in intermittent jets.
Disconnect the shunt.
Reconnect the relay.
Disconnect the battery.Remove the pump-sender unit steel access cover.
Remove the clip which shows if the assembly has
been pushed in (if fitted).
Disconnect the quick release union at (1), tool

IMPORTANT :
During all operations on the fuel tank or on the
fuel supply circuit , it is vital :
- to refrain from smoking and handling incan-
descent objects in the vicinity of the working
area,
- to avoid fuel projections, due to the residual
pressure present in the pipes during removal .
REMOVAL
To remove the pump-sender unit assembly, it is
not necessary to remove the tank, as it is accessi-
ble through the inside of the vehicle. To do this :
- disconnect the battery,
- lift the rear bench seat ,
- remove the steel access cover,
- remove the electrical connection at (1),
- remove the clips at (2).
