AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check with the diagnostic tool.

1.DEFNOTESSpecial notes:
This fault appears when the computer control section has
overheated.
Check the condition of the rail pressure regulator connector (DRV) (see Wiring Diagram Technical Note, Laguna
II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1198).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are 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.
Measure the resistance between connections 3FB and 3RG of component 1198.
If the resistance of the rail pressure regulator connector is less than 2 Ω or greater than 1 kΩ, contact the Techline.
Check the continuity and absence of interference resistance on the following connection:
•3RG between the components 120 and 1198.
Check the +12 V after relay supply to the rail pressure regulator (DRV) on the following connection:
•3FB of component 1198.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, contact the Techline.

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.
