NOTESConditions for applying the fault finding procedure to a stored fault:
The fault reappears after:
– the ignition is switched on,
– the regulator is controlled using command AC225 Rail pressure regulator.
Special notes:
The rail pressure regulator (DRV) is built into the high pressure rail.
The DF898 Rail pressure regulator circuit depends on the pressure regulator on the
rail (DRV).
If the fault is present:
– the quantity of fuel injected is limited and the engine speed is limited to 3000 rpm:
CO, CC.1, 1.DEF,
–the level 2 warning light will be lit,
– the engine stops immediately for CO, CC.1, 1.DEF,
– the engine stops after a few minutes for CC.0,
– the rail pressure is regulated by the pump pressure regulator (MPROP).
Use bornier Elé. 1681 for all operations on the engine management computer
connectors.
