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 – Replacement of components13B
If no communication is possible with the injection computer during reprogramming or programming:
●Clear the programming using command RZ019 Reinitialise programming.
●Clear any faults using command RZ001 Fault memory.
●Enter the V.I.N. using command SC013 Enter VIN code.
●Perform a powerlatch.
●Perform a detection of the cruise control - speed limiter and the air conditioning:
– Vehicle ignition on.
– Main switch in rest position (the computer then detects the rest position).
– Switch in Cruise control position to activate the Cruise control function.
– Switch in Speed limiter position to activate the Speed limiter function.
– Air conditioning in the ON position.
●For Kangoo II, program the values for fast idle speed (if equipped) and vehicle speed restriction (if equipped)
using commands SC041 Modification of commercial vehicle idle speed and SC040 Speed limiter.
●For Vdiag 45, 49 and 4D, carry out a particle filter regeneration using command SC017 Particle filter
regeneration (see Interpretation of commands).
●For Clio III, Modus, Megane II and Scenic II vehicles:
– If the configuration reading LC106 O.C.S. is" WITH" (check in the instrument panel computer), perform
an engine oil change and initialise the value of the oil service interval using the instrument panel.
●For Kangoo II:
– Change the engine oil and initialise the value of the oil change interval using the instrument panel.
IMPORTANT
The injection computer retains the immobiliser code for life.
The system has no security code.
It is forbidden to perform tests with computers borrowed from the Parts Department or from another vehicle
which must then be returned.
These computers are hard-coded.
If the injection computer is faulty, contact the Techline (and refer to the fault finding log).

OIL OXIDATION SIGNAL
PARAMETER
DEFINITIONThis parameter indicates the vehicle mileage when the oil oxidation threshold is
reached.
NOTESOnly apply the interpretation of this parameter if the OCS (oil control system)
program is activated on the instrument panel. Check on the instrument panel computer
that the configuration reading LC106 O.C.S. is set to WITH.
Except Vdiag 44, 45 and 49.
Conformity check: Engine stopped and the ignition on, or the engine running and the engine coolant
temperature > 80°C, without electrical consumers
The oil status is calculated by the oxidation program in the injection computer, depending on the engine revs.
When this count reaches a certain threshold before the end of the oil change period, the injection computer sends
a signal to the instrument panel, which will display "service required soon". PR873 corresponds to the vehicle
distance at the time this signal is sent.
The instrument panel computer counts down 900 miles (1500 km) before displaying the message "service
required".
IMPORTANT
When the message "service required" appears on the instrument panel, the customer must arrange an oil
service within the remaining 900 miles (1500 km).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
