This document presents the fault finding procedure applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type
Fault finding procedures (this document):
– Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
–Visu-Schéma.
Type of diagnostic tools
–CLIP
Special tooling required
3. REMINDERS
Procedure
To save energy, the UCH of the vehicle interrupts the + after ignition feed after 3 minutes.
To run fault finding on a computer, it is possible to force the + after ignition feed for 1 hour by applying the
following procedure:
– Press the card unlocking button,
– insert the card in the reader,
– press the start button (interrupting the timed + after ignition feed mode),
– press the start button for more than 5 seconds, until the immobiliser warning light flashes rapidly (4 Hz).
This forced + after ignition feed mode remains active for 1 hour.
Pressing the start button or removing the card from the card reader interrupts the forced + after ignition feed, but
does not interrupt the timed forced + after ignition feed mode. As long as one hour has not elapsed, activating the
+ after ignition feed will restart forced + after ignition feed for the remaining time. Vehicle(s): Laguna II Phase 2 / Vel Satis Phase 2 /

Warning light management:
Instrument panel display
The computer displays certain information on the instrument panel relating to engine operation. This concerns five
functions:
– the pre-postheating warning light,
– the coolant temperature warning light,
–the level 1 fault warning light (non-critical fault),
–the level 2 fault warning light (emergency stop),
–the EOBD (European On Board Diagnostic) warning light,
These six functions are represented by 3 warning lights and/or messages displayed by the on-board computer.
Orange pre-post heating/non-critical fault SERVICE warning light (severity 1)
This light is used both as an in-operation indicator light and as a system fault indicator:
– Continuously lit with + after ignition feed:
Indicates preheating of the spark plugs.
– Continuously lit with the Check injection message:
Indicates a level 1 fault (involving operation of the injection system in defect mode).
The driver should have the repairs carried out as soon as possible.
Temperature / red emergency STOP warning light (level 2)
This indicator light is used both as an in-operation indicator light and as a system fault warning light. It lights up for
3 seconds after the ignition is switched on (automatic test procedure managed by the instrument panel):
– Continuously lit:
Indicates engine overheating (the driver is free to choose whether or not to stop the vehicle).
– Continuously lit with the faulty injection message:
Indicates a level 2 fault (In this case, the injection is automatically cut after a few seconds).
The driver should carry out repairs as soon as possible.
ORANGE Excessive pollution EOBD warning light
Symbolised by an engine, it lights up for approximately 3 seconds when the ignition is switched on.
This warning light comes on if the system has one or more EOBD faults.
This warning light is used to alert the driver to injection faults that could lead to excessive pollution, or if the EOBD
system (European On Board Diagnostic) has been deactivated.
The injection computer requests illumination of the EOBD warning light for a present fault only after three
consecutive driving cycles.
The 3 second visual inspection when the ignition is switched on (automatic test procedure managed by the
instrument panel) is carried out by the injection computer.
Special particle filter ORANGE warning light or warning message (depending on instrument panel)
Only for Vdiag: 18, 1C, 54, 20, 58, 5C, 24, 26 and 60.
This warning light or message is used to warn the driver that the particle filter is loaded with particles, (see the soot
weight thresholds for illumination of the warning light for fault DF312 Speed request) due to driving conditions which
were not suitable for regeneration to take place. The driver must then drive as soon as possible at an average speed
of 48 mph (80 km/h) subject to the road conditions and authorised speed limits, until the warning light goes out.

REPLACING THE INJECTORS
After one or more injectors have been replaced, enter the IMA codes again and then run command SC036
Reinitialise programming.
To do this, record the IMA code(s) etched on the injector bodies, and enter the codes into the computer using
command SC002 Enter injector codes, and follow the instructions given by the diagnostic tool. Run command
SC036 Reinitialise programming and select injectors, then follow the procedure. Note:
The "IMA" code (individual injector correction) is a calibration with corrective values unique to each injector,
and is used to adjust their flow accurately (injector classification). This correction takes into account mechanical
variances and the variances of the piezo actuator. An injector's class is determined by measurements taken at
different pressures on a test bench. The IMA class identification (7-character alphanumeric code) is then
engraved on the collar of the injector.
The IMA codes must be read from left to right:
– Foolproofing for reading the IMA codes is carried out using the low pressure return connector and/or the
electrical connector on the injector.
– This reading direction is valid when these connectors are located to the left of the cotech.
The IMA codes are read from left to right (see illustration in MR 402 (Vel Satis ph2), MR 395 (Laguna II ph2),
MR 364 (Mégane II ph2), MR 370 (Scénic II ph2), MR 405 (Espace IV ph2) Mechanical, 13B Diesel injection,
Diesel injector, Removal – Refitting)
Note: When entering characters, confusion can arise between:
– Figure 1 and the letters I and L,
– Figure 2 and the letter Z,
– Figure 5 and the letter S,
– Figure 6 and the letter G,
– Figure 8 and the letter B.
After programming or reprogramming the computer, it is essential to enter the 4 injector codes before confirming
the entry.
These individual corrective values are then written to the computer EEPROM, which can then control the injectors,
taking into account their manufacturing variation.
IMPORTANT:
Engines can only operate correctly if the correct IMA* codes have been entered. If no code has been
entered, or if an invalid code has been entered, fault DF066 Injector code(s) is present and the engine will
run in defect mode (engine speed limited significantly). If another injector's code has been entered, the
system will accept it but will make the wrong correction. This could lead to engine damage, loss of
performance and excessive pollution.
Always use the correct injector codes for the engine cylinder/computer.
Note:
On the M9R engine (Renault - Nissan partnership engine), cylinder no. 1 is located at the timing end.

WITHOUTThis status is present on the diagnostic tool if:
the computer has been reinitialised,
The computer has been reprogrammed.
STATUS 1Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active
(ET042 Cruise control / speed limiter: CRUISE CONTROL) and traction control is
requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.

STATUS 7
Lack of correlation between the request and the vehicle speed
Status ET415 becomes STATUS 7 if the computer detects too great a difference
between the speed requested by the driver and the vehicle speed.
This could occur when driving with the cruise control active (ET042 Cruise control /
speed limiter: CRUISE CONTROL) on very steep terrain.
This inconsistency deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 7 where the surface is not uneven, contact the
Techline.
STATUS 8Automatic gearbox in defect mode.
Status ET415 becomes STATUS 8, when driving with cruise control active
(ET042: CRUISE CONTROL) and if the automatic transmission is in defect mode.
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 automatic transmission
computer.
Deal with any present or stored faults (see 23A, Automatic transmission).
Clear the automatic transmission computer memory by running command RZ001.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If STATUS 8 is still present, contact the Techline.

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

TEST3 Low pressure circuit check
Check the fuel filter:
– Conformity of the fuel filter (correct part number and RENAULT filter).
– Positioning and degree of clogging of the filter cartridge.
– Positioning and condition of the seals.
– If there is metal swarf in the filter:
Replace the fuel filter, bleed the circuit and continue the fault finding procedure.
Supplying the injection system with fuel from an additional tank.
This operation aims to detect possible faults in the low pressure supply system of a vehicle by replacing it entirely
with an additional tank.
Mode:
– Disconnect the diesel fuel supply pipe at the fuel filter inlet and block it with a plug.
– Connect a pipe to the fuel filter inlet and insert the other end in a clean container with a capacity of approximately
5 litres.
– Disconnect the diesel fuel return pipe at the diesel temperature sensor (pump return and injector return join), and
block it using a plug.
– Connect a transparent pipe to the union of the diesel fuel temperature sensor, and insert the other end in the
container.
– Fill the container with clean diesel fuel.
– Start the engine and let the system drain itself of its air (there must not be any air bubbles in the return pipe).
Is the customer complaint still present?If the low pressure circuit is in order, reconnect the
various low pressure circuit pipes, and repeat the
fault finding chart procedure or the procedure for
the fault that referred you to this test.
Are the low pressure circuit connections in order
