1. HAZARDS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks caused by the introduction of
contamination are:
– damage to or destruction of the high pressure injection system,
– a component seizing up,
– a component losing its sealing.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles
a few microns in size) should have penetrated the system during dismantling.
The cleanliness guidelines must be applied from the filter through 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,
– the ambient atmosphere,
–etc.
2. 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 faults in the electrical connections.
IMPORTANT
Before carrying out any work 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.

PR002ALTERNATOR CHARGE
PARAMETER
DEFINITIONThis parameter indicates the charge value of the alternator in %.
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, or engine running, and engine coolant
temperature > 80°C
The alternator charge value varies according to the battery voltage.
