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.
Check that you have hermetically resealable plastic bags for storing removed parts. Parts stored in this way will be
less susceptible to the risk of contamination. The bags are to be used once only, and discarded after use. 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.

NO YES
Contact the Techline
NO YES
Check the charge circuit and carry out the
necessary repairs:
– Check the condition of the battery terminals,
– carry out fault finding on the alternator.
Recharge or replace the battery.
YES
Check the condition of the wiring harness between the computer and the battery, carry out the necessary repairs.
– Start the vehicle.
– Clear the stored faults.
– Check the faults:
– If DF038 is stored, end of fault finding.
– If DF038 is present, contact the Techline.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present following a road test or after attempting to start the
engine.
Special notes:
Computer operating voltage: 9 V < PR071 < 16 V.
Battery voltage that is too low can cause the level 1 fault warning light to come on
thereby causing other faults to appear.
It is then not possible to start the engine.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Priorities when dealing with a number of faults:
If this fault is accompanied by DF226 Damper valve circuit 2.DEF: Fault external to
domain, ignore the latter fault as DF046 is the cause of this fault.

Alternator condition (complete fault finding procedure)
Carry out the necessary repairs.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults
The fault is declared present when the ignition is switched on or with the engine
running.
Special notes:
If the fault is present, the level 1 warning light will be lit.
IMPORTANT
The fault can appear after the alternator has been saturated for too long.
For stored faults, clear the fault, switch off the ignition and wait for 1 minute, then
perform a road test to confirm the fault before any carrying out any operation.
Run a multiplex network test (see 88B, Multiplexing).
For Laguna II:
If the fault is still present, check the insulation and continuity of connection 2K between components 120 and 103.
If the connection or connections are faulty and there is a repair method (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.
Carry out a road test followed by another check with the diagnostic tool.

PARAMETER
DEFINITIONThis parameter indicates the alternator flow in mA.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on.
Ignition on: PR016 = 0 mA
In the event of a fault, check the charge circuit.
Conformity check with engine running, engine coolant temperature > 80°C.
Engine running: PR016 ≈ 1500 < PR016 < 2500 mA
With consumers: PR016 ≈ 2500 < PR016 < 3600 mA
In the event of a fault, check the charge circuit.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
