NOTESCarry out this fault finding procedure when the interpretation of fault DF304 EGR
bypass circuit has not been resolved.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
Measure the resistance between connections 3FB and 3TP of component 1301.
If the resistance of the solenoid valve is not between:
•43 Ω and 49 Ω at + 25 °C,
•32 Ω and 37 Ω at - 40 °C, replace the EGR bypass solenoid valve.
Check the continuity and the absence of interference resistance on the following connection:
•3TP between components 120 and 1301.
Check the + 12 V after relay supply to the EGR bypass solenoid valve of the following connection:
•3FB of component 1301.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If you notice no valve movement when running command AC103, ensure that the computer output stage is
functioning:
Vehicle under + after ignition feed, clear the faults displayed by the diagnostic tool.

With the voltmeter in the direct current position:
With the EGR BYPASS solenoid valve connected, connect the voltmeter earth lead to connection3TP of
component1301 and the positive lead to connection3FB of component1301. Run command AC103, the
voltmeter should display four successive readings which are approximately equal to the 12 V battery voltage.
If the voltmeter indicates no control or a continuous voltage, contact the Techline.
If activation has run correctly, check the control vacuum:
– Disconnect the solenoid valve inlet hose and connect it to a pressure gauge.
– Start the engine and run it at a stable idle speed.
– If the vacuum does not reach a value between 0.250 bar and 0.550 bar, check the vacuum circuit from the
vacuum pump.

Fault finding – Interpretation of commands13B
MT001TURBOCHARGING FUNCTION
NOTESPerform this fault finding procedure:
– following the interpretation of a fault concerning the air line which cannot be rectified,
– following an inconsistency found in the parameters concerning the air line
(turbocharging pressure or inlet air flow),
– following a customer complaint (starting faults, engine speed instability, lack of
power).
NOTESThis fault finding mode allows you to check dynamically certain mechanical components
on the engine.
To do this, the engine will run a 4-phase cycle which will enable the entire air line to be
checked: air filter, air flowmeter, duct (hoses), air refrigerant, turbocharging pressure
sensor, turbocharger, inlet manifold, exhaust manifold and exhaust pipe.
This test lasts for approximately 50 seconds.
Interpretation of test results:
The data recorded during this test is displayed in the DATA section.
- Identify any data which is outside the tolerance range and apply the different Monitool fault finding procedures
if necessary.
Introduction:
Engine parameters used during this test:
– PR055 Engine speed
– PR035 Atmospheric pressure
– PR059 Inlet air temperature
– PR064 Coolant temperature
–PR132 Air flow
– PR041 Turbocharging pressure
– PR051 EGR valve position feedback

PHASE 1:
Preliminary test:
Engine speed between: 2480 rpm < X < 2520 rpm
Coolant temperature > 70°C
EGR valve feedback position < 1%
If data from the preliminary checks indicates a non-conformity, check the fuel circuit then contact the Techline.
Interpretation:
If, during phase 1, no data is outside the maximum and minimum limits for each variable, interpret the Monitool
analysis for phase 2.

Interpretation:
If, during phase 2, no data is outside the maximum and minimum limits for each variable, interpret the Monitool
analysis for phase 3.
Note: the interpretation of faults during phase 2 should only be carried out in the following situation:
– The variables measured during phase 1 are correct, i.e. they are within the maximum and minimum authorised
limits. If this is not the case, apply the different Monitool fault finding procedures which relate to the different faults
revealed during the phase 1. To confirm the repairs or modifications carried out, run the MT001 monitool test
again.

Interpretation:
If, during phase 3, there is no data outside of the maximum and minimum limits for each variable, then the air line
is correct and no component replacement is to be carried out. Check the fuel circuit or deal with present or stored
faults which are displayed on the diagnostic tool.
Note: the interpretation of faults during phase 3 should only be carried out in the following situation:
– The variables measured during phase 1 and 2 are correct, i.e. they are within the minimum and maximum
authorised limits. If this is not the case, apply the different Monitool fault finding procedures which relate to the
different faults revealed during the phase 1 and phase 2. To confirm the repairs or modifications carried out, run
