TEST 6 High pressure system check
NOTESSpecial note:
Certain faults make it impossible to carry out this test - deal with these first.
WARNING
Running the starter motor for more than 5 seconds is dangerous and serves no useful
purpose.
Preliminary Checks:
– Check for the presence of fuel
– Check that there is no air in the low pressure circuit. Apply TEST 1 Low pressure circuit check.
– Ensure that the correct fuel is being used. Apply TEST 13 Diesel fuel conformity check.
The pump's capacity to produce high pressure can be checked by the following procedure:
–With the ignition off, disconnect the low pressure actuator from the pump (IMV brown connector) and
connect a test IMV or the MOT adapter. 1711 adapter.
– Electrically disconnect the four injectors.
– Switch on the ignition, connect the diagnostic tool and re-establish dialogue with the injection system.
– Go to the Main computer statuses and parameters screen.
– Run the test cold, PR064 "Coolant temperature" < 30 °C or equal to ambient temperature.
–Activate the starter for 5 seconds.
– Read the maximum rail pressure value PR038 Rail pressure during the test on the diagnostic tool.
PR038 > 1050 bar?

TEST 8 Injector return flow
NOTESSpecial note:
Certain faults make it impossible to carry out this test - deal with these first.
Does the engine start?
Command AC029 High pressure circuit sealing also checks the return volume of each injector to detect any
leaks around the injectors.
Be careful with any objects (tool or other) on the engine housing during the four cycles of the operation
(possible vibrations).
Tooling required
–Mot. 1711 Injector flow measuring kit.
Or: Use four pipes with internal diameter 4mm and approximately 50 cm in length, and four graduated
measuring cylinders.
Procedure
– Ensure that the engine coolant temperature is above 60°C,
– switch off the ignition,
– disconnect the return pipes from the four injectors,
– cap the pump venturi tube to prevent the low-pressure circuit from depriming,
– connect the four transparent tubes in place of the return pipes,
– put the other ends of the four pipes into four graduated measuring cylinders.
