PR879MAXIMUM AUTHORISED SPEED
PARAMETER
DEFINITIONThis parameter indicates the maximum authorised speed in mph (km/h) requested by
the customer using command SC040 Speed limiter.
NOTESSpecial notes:
It is possible to modify the value of PR879 using command SC040 Speed limiter.
This parameter is valid only on Kangoo 2.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
If ET741 "Optional vehicle speed restriction" is ACTIVE, the value of PR879 is between 18 mph (30 km/h) and
150 mph (250 km/h).
In the event of a fault or modification of this speed, use command SC040 Speed limiter.

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. Run TEST 1 Low pressure circuit check.
–Ensure that the correct fuel is being used. Run 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 adapter of MOT. 1711.
–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.
–Engage the starter for 5 seconds.
–Read the maximum rail pressure value PR038 Rail pressure during the test on the diagnostic tool.

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 inside 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 tubes of internal diameter 4 mm and approximately 50 cm long, and four graduated measuring
cylinders.
Procedure
–Check 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.
When all the preparations are complete, start the engine and leave it running:
30 secondsfor Euro 4 engines: K9K 766 - 768 (Clio III and Modus); K9K 724 (Mégane II
and Scénic II); K9K 740 -718 (New Twingo); K9K 800 - 802 - 812 (Kangoo 2).
Let it idle for 2 minutesfor Euro 3 type engines: K9K 750 - 752 (Clio III and Modus).
Note:
These time periods must be respected for the test results to be interpreted correctly.
–Run command AC029 High pressure circuit sealing check.
The engine will carry out automatically a cycle of four accelerations to increase the rail pressure and measure
internal injector leaks under these conditions.
–When the cycle has finished, run command AC029 High pressure circuit sealing test a second time to
obtain the correct return volume reading for each injector.
–Switch off the engine at the end of the cycle.

TEST 10 Turbocharger solenoid valve check
Note:
No turbocharger control solenoid valve present on the K9K 740 engine for New Twingo and the K9K 800
engine for Kangoo 2.
Checking the vacuum at the pressure regulator inlet
Run the engine at idle speed.
Check the engine temperature using the CLIP parameter PR064 Coolant temperature.
Let the engine warm up until the temperature reaches 80
°C.
Disconnect the vacuum pipe from the end piece of the pressure regulator.
Connect a vacuum pressure gauge to the end of the disconnected pipe and put it in the vacuum measurement
position.
Perform a quick acceleration by depressing the accelerator pedal completely and then releasing it immediately.
The total duration of pressing and holding in the full load position must not exceed 1 second.
During this acceleration, the engine speed must reach a value between 3000 and 4000 rpm.
Repeat the operation 3 times.
Read the maximum vacuum posted by the pressure gauge during the increase and decrease in the speed and after
the return to idle speed.
Tolerance intervals for the vacuum are:
–1 bar < CORRECT vacuum value < - 0.6 bar
–0.6 bar < INCORRECT vacuum value < 0 bar
Is the vacuum at the turbocharging pressure regulator inlet displayed on the vacuum gauge within
the tolerance interval?
The solenoid valve is in order.
NOYES
