Fault finding – Cleanliness guidelines
I - HAZARDS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks associated with
contamination are:
– damage to or destruction of the high pressure injection system,
– components jamming,
– a component leaking.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles a
few microns in size) should have entered the system during dismantling.
The cleanliness principle must be applied from the filter to the injectors.
What are the sources of contamination?
– metal or plastic swarf,
– paint,
–fibres:
– from cardboard,
– from brushes,
– from paper,
– from clothing,
– from cloths,
– foreign bodies such as hair,
–ambient air
–etc.
II - INSTRUCTIONS TO BE FOLLOWED PRIOR TO ALL OPERATIONS
Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department). The plugs
are single-use only. After use, they must be discarded (once used they are soiled and cleaning is not sufficient to
make them reusable). Unused plugs must be discarded.IMPORTANT
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections. In
addition, moisture may collect in the connectors and create electrical connection faults.
IMPORTANT
Before any work is carried out on the high pressure injection system, protect:
– the accessories and timing belts,
– the electrical accessories, (starter, alternator, electric power-assisted steering pump),
– the flywheel surface, to prevent any diesel from running onto the clutch friction plate.

Fault finding – Function13B
Cruise control/speed limiter on/off switch:
This switch turns the cruise control/speed limiter on or off.
Water in diesel fuel sensor (optional):
This sensor indicates if water is present in the diesel.
Fan unit relay:
This relay actuates the motor-driven fan assemblies when a temperature threshold has been exceeded.
Accelerator potentiometer:
The accelerator potentiometer informs the computer about the position of the accelerator pedal (engine load).
Brake pedal switch:
The brake pedal switch informs the computer about the pedal status.
Clutch pedal switch:
The clutch pedal switch informs the computer about the pedal status.
Particle filter injector:
The particle filter injector is a low pressure injector. This injector allows the temperature of the second catalytic
converter to be raised to assist with regeneration of the particle filter (Vdiag 45, 49, 4D only).
Only on Kangoo 2: an evaporator plate is present at the particle filter injector outlet, at the level of the bracket
between the exhaust pipe and the catalytic converter.
Heating elements:
The heating elements heat the engine coolant to enhance user comfort (Vdiag 45, 49, 4D only).
Heater plugs:
The heater plugs preheat the combustion chamber so that the explosion of the fuel mixture occurs under the best
conditions to start the engine.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after a series of actions on the clutch pedal during a
road test (speed greater than 54 mph (90 km/h)).
If the fault is present:
Engine bucking or high engine speed.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Check the connection and condition of the clutch switch connector, component code 675 (see MR 392, 385,
364, 370 and 417, Mechanical, 37A, Mechanical component controls, Clutch pedal position sensor:
Removal - Refitting) and the injection computer connector, component code 120 (see MR 392, 385, 364, 370
and 417, Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s); otherwise, replace the wiring.
With the ignition on, check the + 5 V clutch switch signal on connection86D and earth on connectionM (or
NAM for Kangoo II).
If correct:
Check the conformity and adjustment of the clutch switch (position, connection).
– display status ET121 Clutch contact signal:
– when the clutch pedal is engaged, status ET121 should be INACTIVE,
– when the clutch pedal is disengaged, status ET121 should be ACTIVE.
If these checks are not correct, replace the clutch switch (see MR 392, 385, 364, 370 and 417, Mechanical,
37A, Mechanical component controls, Clutch pedal position sensor: Removal - Refitting).
If the supply to the switch is incorrect:
Check the insulation, continuity and the absence of interference resistance on the following connections:
–86D between components 675 and 120,
–M (or NAM for Kangoo II) between components 675 and 120.
If the connection(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present with the engine running and an air conditioning request.
Order of priority in the event of more than one fault:
Deal with fault DF049 Refrigerant sensor circuit first if it is present or stored.
Use the CLIO III, MODUS, MEGANE II ph2 and SCENIC II ph2 Wiring Diagrams
Technical Note.
When the fault is present or stored, the heating and air conditioning system is inhibited. There is no longer any air
conditioning.
Check the air conditioning fuse and check the air conditioning compressor connector, component code 171.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the continuity and insulation of the following connections:
– 38R between components 171 and 1337,
– Mbetween the earth and component 171.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Manually check if the compressor is jammed (turn the clutch plate manually to check that there is no point of
resistance).
In the event of jamming, replace the air conditioning compressor (see MR 364 (Mégane II), MR 370 (Scénic II),
MR 385 (Modus), MR 392 (Clio III), Mechanical, 62A, Air conditioning, Compressor:
Removal - Refitting)
Charge the air conditioning circuit, check for any leaks and repair if necessary (see MR 364 (Mégane II), MR 370
(Scénic II), MR 385 (Modus), MR 392 (Clio III), Mechanical, 62A, Air conditioning, Air conditioning: Check
and air conditioning:
Draining - Filling).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
