AC004TURBOCHARGING SOLENOID VALVE
NOTESPerform this fault finding procedure:
– following interpretation of an unresolved fault or,
– following application of the interpretation of PR041 Turbocharging pressure or
– after a customer complaint (loss of power, smoke etc.).
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
1. The following procedure is for checking that the turbocharger and its control circuit are working
properly.
Preliminary operation
Check the high pressure air circuit is sealed:
Apply Test 4 Turbocharged air inlet circuit check or Test 3 Low pressure circuit check.
Pipe not joined or pierced, pressure sensor disconnected or poorly fitted (seal present), exchanger pierced.
To test the exchanger: stabilise the engine speed between 3500 and 4000 rpm with the vehicle stopped and
check that there are no leaks.
Measure the resistance between connections3FB and 3MG of component1475.
If the resistance is not between 18 Ω and 22 Ω at + 23°C, replace the turbocharging solenoid valve.
Check the continuity of the following connection:
•3MG between the components 120 and 1475.
Check the + 12 V after relay supply of the turbocharging solenoid valve on the following connection:
•3FB of component 1475.
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.

AC012DAMPER VALVE
NOTESCarry out this interpretation:
– after DF645 Damper valve position regulation, DF646 Damper valve position
sensor,
– or after a customer complaint (starting faults, poor performance).
Use the Wiring Diagram Technical Note, Laguna II ph2, Mégane ll, Scénic ll,
Espace IV ph2, Vel Satis ph2.
Measure the resistance between connections 38KQ and 38KP of component 1461.
If the resistance is not between 875 Ω and 1625 Ω replace the damper valve.
Check the continuity and absence of interference resistance of the following connections:
•38KQ between components 120 and 1461,
•38KP between components 120 and 1461.
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.
With the vehicle ignition on, and the engine stopped:
Make sure the damper flap is open,
If not, clean or replace the damper valve.
Actuate the valve using command AC012 and check the damper valve travel and rest position of the valve.
Check the operation of the computer output stage with a voltmeter in the alternating current position:
Actuate the valve with command AC012.
Connect the voltmeter earth lead to connection 38KS of component 1461 and the positive lead to connection
38KQ of component 1461.
The voltmeter should display three cycles of ON-OFF (12.5 V then return to 0V).
If the measurement is correct, replace the damper valve
If the measurement does not show any operation, contact the Techline.

STEP 2
In the event of rail overpressure:
Check that there are no air bubbles in the diesel fuel low pressure circuit.
Check that the rail pressure sensor is working, and then interpret parameter PR038 Rail pressure.
If these checks do not reveal any faults, replace the rail regulator.
in the event of rail underpressure:
Check the correct operation of the rail pressure sensor, as well as the interpretation of parameter PR038.
Check the low pressure diesel circuit priming.
Check the conformity of the diesel filter connections.
Check the condition of the filter (clogging and water saturation).
Check that there are no air bubbles between the filter and the high pressure pump.
Check the sealing of the low and high pressure diesel fuel systems: use ALP6 Fuel circuit leaks (visual
inspections, touch tests, odours, etc.) on:
pump body, pressure release valve, pipes, rail and injectors unions, injector wells, etc.
Check the conformity of the seal fitting on the pressure regulator.
Check the operation of the injectors: run Test 10 Incorrect injector operation.
Carry out the necessary repairs.
If the engine starts:
Clear any faults.
Check the rail pressure regulator using ALP7 Rough idling.
With the engine warm, leave it to idle for a few minutes (3 to 5 minutes):
– If it stalls and the fault reappears, replace the rail pressure regulator.
– If it does not stall, stabilise the engine speed at 2000 rpm (1 minute) then depress the accelerator fully until the
maximum engine speed imposed by the computer is obtained (~5500 rpm). The maximum rotation speed of the
engine must be stabilised in the time taken to fully depress and then fully release the pedal. This test is carried
out with no load (engine in neutral).
– If the engine stalls, contact the Techline
If the engine does not start or there is no timing, first replace the rail pressure regulator.
If the fault is still present, contact the Techline
