STATUS 9
Vehicle speed monitoring.
Status ET415 becomes STATUS 9 if the vehicle speed received by the computer is
invalid or absent.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then run fault finding on the ABS computer.
Deal with any present or stored faults (see 38C, Anti-lock braking system,
Interpretation of faults).
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If STATUS 9 is still present, contact the Techline.
STATUS 10Monitoring by injection computer.
Status ET415 becomes STATUS 10 when driving with cruise control active
(ET042 Cruise control / speed limiter: CRUISE CONTROL) and if the injection
computer detects a fault anywhere in the engine management system, or an
engine overspeed or underspeed.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then Perform fault finding on the injection computer.
Deal with any present or stored faults (see Interpretation of faults).
Reinitialise status ET415 on the injection computer by running command RZ001.
If STATUS 10 is still present, contact the Techline.

PR089VEHICLE SPEED
PARAMETER
DEFINITIONGives the vehicle speed in km/h.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
This parameter is transmitted by the ABS computer. This signal is transmitted to the
injection on the multiplex network.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
In the event of a fault, test the multiplex network (see 88B, Multiplex).
And then complete fault finding on the ABS computer (see 38C, Anti-lock braking system).

Sensor electrical conformity
Check the air inlet circuit (from the air filter inlet to the inlet manifold,
apply Test 4 Turbocharged air inlet circuit check):
– air filter unit inlet not blocked and filter not clogged,
–visual inspection only, apply Test 4 of ALP 2 Starting fault or starting impossible,
– oil vapour recirculation circuit connection conformity.
–absence of leaks or blockages in the low and high pressure air circuits: pipes, presence and tightness of the
mounting clips, mounting of the turbocharger pressure sensor, intercooler, etc.
– check that the damper valve is not jammed closed.
Carry out the necessary repairs.
Check the electrical conformity of the air flowmeter:
Check the + 5 V supply of the air flowmeter on the following connection:
•3KJ of component 799.
Check the + 12 V after relay supply of the air flowmeter on the following connection:
•3FB of component 799.
Check the continuity and absence of interference resistance of the following connections:
•3DV between components 120 and 799,
•3DW between components120 and 799.
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 flowmeter connected, the vehicle ignition on, and the engine stopped:
Check the voltage between connections 3DW and 3DV of component 799.
If the air flow sensor voltage is not between 0.3 V < X < 0.7 V, replace the sensor.

SC017PARTICLE FILTER REGENERATION
NOTESOnly run this command after interpretation of the following faults:
– DF308 Clogged particle filter,
– DF311 Failed regenerations limit exceeded,
– df312: speed request.
WARNING:
– It is essential to observe the health and safety guidelines (see MR364 (Mégane II ph2), MR370 (Scénic II ph2),
MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2) Mechanical, 19B, Exhaust, Particle
filter: Cleaning) and follow the procedure below.
SAFETY INSTRUCTIONS TO BE FOLLOWED:
The regeneration causes exhaust fumes and high temperatures.
It is strongly recommended that you put the vehicle outside during regeneration.
If it is not possible to carry out regeneration outside, use an extractor fan that can withstand the very high
regeneration temperatures (400°C at the exhaust outlet).
Perform regeneration on a surface free from fire risks (oil, dry leaves, etc.).
Nothing should be left in the vicinity of the exhaust pipe.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
WARNING:
Check the engine oil level before running the command to avoid any engine racing. The oil level must be
between the minimum level and the middle level on the oil dipstick.
Before performing a particle filter regeneration, it is essential to deactivate the air conditioning
compressor (risk of engine damage) and all the electrical consumers.
IF NECESSARY:
Regeneration can be stopped by pressing the engine start button twice briefly (less than 3 seconds).
Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication
lost with computer: EDC16 C33, check the tool connection and the computer power supply before
switching the ignition back on.

Run compressions on all cylinders.
Are the compressions correct?

Run command AC004; if a faint whistling noise is heard along with a clicking from the solenoid valve, go to STEP
2, otherwise check the operation of the computer output stage:
Vehicle under + after ignition feed, clear the faults displayed by the diagnostic tool.
With the voltmeter in the direct current position:
With the turbocharging solenoid valve connected, connect the voltmeter earth lead to connection 3MG of
component 1475 and the positive lead to connection 3FB of component 1475. Run command AC004; the
voltmeter must display four successive voltages between 2.2 V and 2.6 V.
If the measurement is not correct, contact the Techline.
2. turbocharger control circuit check
–Apply Test 7 Variable geometry turbocharger control.
– With the engine stopped, make sure that the control rod is in the resting position.
– Start the engine and make sure that the control rod actuates to the upper stop.
(when the engine stops, the control rod should return to the rest position).
If the control rod does not move correctly, carry out the following checks:
1. 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.
– Stop the engine, reconnect the inlet hose and move onto step no. 2.
2. Check the solenoid valve actuation:
– Disconnect the solenoid valve outlet hose.
– Start the engine and run it at a stable idle speed.
– Place your hand on the solenoid valve and block the outlet union with your thumb.
– If there is no perceptible vibration of the solenoid valve, contact the Techline.
3. Check the solenoid valve actuation:
– Connect the pressure gauge to the solenoid valve outlet union.
– 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, replace the solenoid valve.

VP036INHIBIT FUEL SUPPLY
NOTESThis command enables you to disable the supply to the injectors.
This command is carried out with the engine switched off, and ignition on.
This command allows the injectors to be locked, so that starting is not possible.
Command VP036 allows the engine compressions to be checked in complete safety without disconnecting the
connectors of the injectors or the TDC sensor.
Procedure to follow (cylinder no. 1 is located on the timing end):
– Remove all of the heater plugs, connect the compression gauge with the M9R flexible end piece, part no.
MOT 1772, to a cylinder.
– Position the gear lever in neutral (manual gearbox) or to position P (automatic/sequential gearbox).
– Depress the brake pedal and keep it in this position throughout the test.
– Activate command VP036.
– Attempt to start the vehicle (within 10 seconds of activating command VP036).
If the vehicle does not start, check the cylinder compressions.
Start the procedure again on another cylinder.
WARNING:
Keep the brake pedal depressed for the length of the test.
This command is inhibited automatically after 10 seconds.
