I - CHECK PREPARATION OPERATION
- Remove:
- the engine cover,
- the heater plugs.
- Fit the hose (Mot. 1772) in place of one of the removed
plugs.
- Moderately tighten the hose (Mot. 1772) (1) using
an open-jawed spanner.
- Screw the conversion hose end piece (Mot. 1772)
(2) of the diesel compression gauge onto the
hose.
- Moderately tighten the end piece onto the hose
(Mot. 1772).
- Connect the diesel compression gauge (3) on the
(Mot. 1772).
- Open the discharge valve (4) of the diesel compression
gauge to release the pressure.
- Close the discharge valve (4) of the diesel compression
gauge.
- Run the command VP 036: " INHIBITION D'ALIMENTATION
DE CARBURANT " using the Diagnostic
tool.
- Put the vehicle under starting conditions:
- manual gearbox in neutral,
- brake pedal released.
II - CHECKING OPERATION
- Connect a self-contained starter or an automatic
battery charger.
Note:
The engine will be turned by the starter for 20 s,
without starting. |
- Press the vehicle start button to trigger the engine
starting phase.
Note:
It is necessary to wait for at least 10 seconds
before starting the engine each time (the starter
will not run due to its thermal protection). |
- Open the discharge valve to release all of the pressure
from the diesel compression gauge.
- Make progress with the diagram sheet.
- Repeat this process for other cylinders.
- Compare the values obtained.
III - FINAL OPERATION.
- Remove:
- the diesel compression gauge,
- the hose end piece (Mot. 1772).
- Refit:
- the heater plugs,
- the engine cover.
- Run the command VP 037: " ARRÊTER L'INHIBITION
D'ALIMENTATION EN CARBURANT " using
the Diagnostic tool.
Note:
If the engine does not start, run the command VP
037: " ARRÊTER L'INHIBITION D'ALIMENTATION
EN CARBURANT " using the Diagnostic
tool or switch off the ignition and wait for 3 minutes
and restart the engine. |

I - PREPARATION OPERATION FOR CHECK
IMPORTANT
To prevent the vehicle from falling, lash it to the
vehicle lift using a strap. |
- Position the vehicle on a two-post lift.
- Remove the cover (1) from the Protection and
Switching Unit.
- Remove the fuse (2) of the fuel pump(F13) (15A).
- Release the fuel pressure in the fuel supply pipe after
the engine has started.
Note:
After switching the engine off, start it again two or
three times to fully relieve the fuel pressure. |
- Remove:
- the engine cover,
- the air resonator located on the rocker cover.
- Disconnect the ignition coil connectors.
Note:
Remove all the engine spark plugs. |
- Remove:
- the ignition coils.
- the spark plugs.
- Connect a petrol compression gauge (3) .
ND5 or ND8
- Put the vehicle under starting conditions:
- gear lever in neutral for manual gearbox,
- brake pedal depressed.
FK0 or FK8
- Put the vehicle under starting conditions:
- gear lever in neutral for automatic gearbox,
- brake pedal depressed.
II - TEST OPERATION
- Press the vehicle start button to trigger the engine
starting phase.
Note:
The engine will be driven by the starter for 20 s,
without starting. |
- Measure the engine compressions, cylinder by cylinder,
at an engine speed of 250 rpm.
- Check the compression pressure value:
- standard compression pressure: 14.4 kg/cm²,
- minimum compression pressure: 12.1 kg/cm²,
- compression pressure differential limit between the
cylinders: 1 kg/cm².
III - FINAL OPERATION
- Disconnect the petrol compression gauge.
- Refit:
- the spark plugs
- the ignition coils
- Connect the ignition coil connectors.
- Refit:
- the air resonator located on the rocker cover
- the engine cover
- the fuel pump fuse
- the Protection and Switching Unit cover.
- Press the vehicle start button to start the engine.
