Fault finding – Interpretation of commands13B
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.

ALP6 Fuel system leaks
NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
IMPORTANT:
Please observe the cleanliness guidelines and safety advice.
Procedure for checking for an external leak on the fuel circuit:
Clean away traces of grease with clean thinner and wipe the part or parts concerned with cleaning cloths.
Start the engine and increase the engine temperature until the diesel fuel reaches 40/50°C.
Stop the engine and check for traces of grease on the part or parts concerned.
If this is the case, replace the part or parts concerned.
Does the priming bulb show traces of grease?
(Visual and tactile inspections)
Check the assembly of the components and
the condition of the seal at the union of the two
components, if the leak is at the seal.
Replace the part or the parts concerned.
Bleed the fuel circuit and continue the checks.
Check the counter pressure valve located on
the fuel return line, after the injectors. Does the diesel filter show traces of grease?
(Visual and tactile inspections)
Do the fuel return pipes show traces of grease?

Fault finding – Test13B
TEST1 Exhaust system check
Engine stopped: Check that the silencer outlet is
not blocked. Repair or replace the silencer, if
necessary.
Check the seal of the exhaust manifold on the
contact surface between the turbocharger and the
exhaust manifold.
Is the seal in order?Repair or replace the faulty part.
Loosen the catalytic converter on the turbocharger
side.
Place a wooden block between the two parts.
Start the vehicle and check if the engine runs
better.
Is the engine running normally?The exhaust system is not the cause of the fault;
repeat the engine fault finding (see Customer
complaints - Fault finding chart).
Retighten the catalytic converter.
Loosen or separate the particle filter on the
catalytic converter side. Place a wooden block
between the two parts if necessary.
Start the vehicle and check if the engine runs
better.
Is the engine running normally?Replace the catalytic converter.
