Immobiliser function
This vehicle is fitted with an engine immobiliser controlled by a random rolling code key recognition system.
REPLACING AN INJECTION COMPUTER
The injection computers are supplied without a code but they must all be programmed with one.
When the computer is replaced, the vehicle code must be programmed in and then a check must be made to ensure
that the immobiliser system is operational.
To do this, simply switch on the ignition for a few seconds without starting the engine then switch it of f. When the
ignition is off, the engine immobiliser function will be activated after approximately 10 seconds (red engine
immobiliser warning light flashes).
IMPORTANT:
With this engine immobiliser, the computer keeps its immobiliser code for life.
In addition, this system does not have a security code.
Consequently, it is forbidden to perform tests with computers borrowed from the stores or from another
vehicle which must then be returned.
It will no longer be possible to decode them.

Reprime the circuit:
– close the fuel cock (R),
– start the low pressure pump while switching on the
ignition several times,
– start the engine,
– OPEN THE FUEL COCK (R) (the valve is open
when the two coloured lines are aligned).
NOTE: certain vehicles are not fitted with a fuel cock.
In this case, ignore the repriming procedure.

After any intervention, check that there are no
leaks in the diesel circuit. Start the engine at idling
speed until the fan starts up, then accelerate several
times under no load.

Checking diesel pressure and flow
It is possible to check the pressure and flow in the low pressure fuel circuit.
The low pressure is delivered by the supercharging pump (electric pump located under the diesel filter designed to
feed the high pressure pump).
SPECIAL TOOLING REQUIRED
Mot. 1311-01
Pressure gauge or
Mot. 1328
Mot. 1311-08 Pressure measuring connector
ESSENTIAL SPECIAL TOOLING
Graduated 2000 ml test tube
CHECK LOW PRESSURE
(SUPERCHARGING PUMP)
Place a "T" connector Mot. 1311-08, to position the
pressure gauge Mot. 1311-01 or Mot. 1328 at the
outlet (S) of the fuel filter or at the HP pump inlet.
Turn the fuel pump using the diagnostic tool or by
directly feeding the pump (each time the ignition is
switched on the low pressure pump is supplied for
30 seconds).
Measure the pressure which should be between
2.5 and 4 bars.CHECK THE FLOW (SUPERCHARGING PUMP)
Make the pump flow into a 2000 ml graduated test
tube. Turn on the ignition to run the pump. The pump is
supplied for 30 seconds if the engine is not started.
The flow read should be 80 to 100 litres/hour
minimum.
IMPORTANT: it is forbidden to measure the
pressure and the flow of the high pressure pump.
