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.

There must be no present or stored faults:
Perform this fault finding procedure if there is a fault with the passenger compartment
heating - demisting.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
If the Thermoplunger no. 3 relay or the additional heater interface unit does not function when command
AC031 is run.
Check the condition of the thermoplunger 3 relay mounting on the engine fuse box or the additional heater
interface unit (see Wiring Diagram Technical Note, Vehicle, component code 1069 or 1550).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Vehicle, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
if the fault is still present, check as follows that this relay is controlled by the engine management computer:
Disconnect the thermoplunger no. 3 relay and fit a 50 Ω to 100Ω resistor on its mounting instead of the coil and
connect a voltmeter as follows:
– positive terminal to + 12 V battery,
– negative terminal to connection 3JAB of component 1069 or 1550.
Run command AC031.
If the voltmeter indicates the battery voltage (4 ON-OFF cycles of 10 seconds), replace the thermoplunger no. 3
relay.
If the voltmeter does not show the battery voltage (4 ON-OFF cycles of 10 seconds), contact the Techline.

AC037PREHEATING RELAY
NOTESThis command is only run if fault DF025 Preheating unit diagnostic connection or
DF017 Preheating unit control circuit is present or stored and if no other fault is
present.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
IMPORTANT:
– Please observe the cleanliness guidelines and safety advice.
– Make sure the correct type of plug is fitted on the vehicle, slow or fast:
Slow plugs have a black ring
Quick plugs have a white ring.
For Vdiag 20, 24, 34, 38 and 74, if replacing heater plugs by plugs of a different type
(see Replacement of components and Replacing heater plugs).
Before applying the following fault finding procedure, check that the battery voltage is not below 12 V. Otherwise,
recharge the battery.
STEP 1:
Using a multimeter fitted with a current clamp, bring together the 4 heater plug supply wires.
Run command AC037 and measure the current consumed by the 4 heater plugs.
If the value of the current consumed is not between 60 A and 80 A, move on to step 2, otherwise end of fault
finding.
