The vehicle has entered the "Flow capacity function"
program. This function is activated more easily when:
the external temperature is high, the fuel level in the
tank is at 1/4, the vehicle is laden and if the vehicle
speed is high. Check the high pressure pump: run TEST 6
High pressure system check.
Is the "Flow capacity function"
programming active?
Check the computer:
Check that the computer connectors are
properly locked.
Check the condition of the computer
connections (bent pin, signs of corrosion,
silicone, etc.).
If the connector(s) is faulty and if there is
a repair procedure (see Technical Note
6015A, Repairing electrical wiring, Wiring:
Precautions for repair), repair the connector,
otherwise replace the wiring.Check the diesel filter.
