PARAMETER CHECK
NOTESOnly perform this conformity check after a thorough check with the diagnostic tool.
The values shown in this conformity check are given as a guide.
Application conditions: Engine stopped, ignition on.
FunctionParameter or status
checked or actionDisplay and notes Fault finding
Idle speed
regulationPR010:Idle speed
regulation
setpointShows the speed of rotation
that the engine should reach
at idle speed: approximately
825 rpm.In the event of a fault, consult the
interpretation of faults DF007 Rail
pressure sensor circuit, DF024
Low pressure actuator control
circuit and DF053 Rail pressure
regulation function.
Accelerator
pedalPR030:Accelerator
pedal
positionPR030 = 0% (pedal
released)
Gives the accelerator pedal
position in %.In the event of a fault, apply the
interpretation of faults DF008 Pedal
potentiometer circuit gang 1,

voltage.
Coolant
temperaturePR064:Coolant
temperatureWarm: 90°C
Indicates the engine coolant
temperature in °C.
Default value: 80°C.In the event of a fault, consult the
interpretation of parameter PR064.
Vehicle speedPR089:Vehicle
speedGives the vehicle speed in
mph (km/h).See fault finding for the ABS (see
38C, Anti-lock braking system).

Control the injectors using commands:
– AC005 Cylinder 1 injector,
– AC006 Cylinder 2 injector,
– AC007 Cylinder 3 injector,
– AC008 Cylinder 4 injector.
Can you hear the valve moving when you are 1 metre
from the vehicle?Run TEST 9 Diesel filter check.
If the test is correct, only replace the faulty
injector(s) (see MR 388 (Logan/Sandero),
MR 451 (Duster), MR 423 (Thalia 2/Symbol
2) or MR 374 (Kangoo VLL), Mechanical,
13B, Diesel injection, Diesel injector:
Removal - Refitting).
Check the high pressure system by running TEST 6 High pressure system check.
Check the condition of the computer connections (for bent pins, signs of oxidation, silicone, etc.) and check that
the computer connectors lock correctly.
