PR006RAIL PRESSURE REGULATOR CURRENT
PARAMETER
DEFINITIONThis parameter indicates the current absorbed by the rail pressure regulator in mA.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check: Engine stopped and ignition on, or Engine running, and engine coolant
temperature > 80°C
This parameter indicates the current absorbed by the rail pressure regulator PR006 ≈ PR007 Rail pressure
regulator current setpoint.
In the event of a fault, consult the interpretation of fault DF898 Rail pressure regulator circuit.
