Fault finding – Cleanliness guidelines
I - RISKS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks associated with
contamination are:
–damage to or destruction of the high pressure injection system,
–components jamming,
–a component leaking.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles a
few microns in size) should have entered the system during dismantling.
The cleanliness principle must be applied from the filter to the injectors.
What are the sources of contamination?
metal or plastic swarf,
–paint,
–fibres:
–from cardboard,
–from brushes,
–from paper,
–from clothing,
–from cloths,
–foreign bodies such as hair,
–ambient air,
–etc.
II - NOTES TO BE FOLLOWED BEFORE ANY OPERATION
Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department). The plugs
are single-use only. After use, they must be discarded (once used they are soiled and cleaning is not sufficient to
make them reusable). Unused plugs must be discarded.IMPORTANT
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections. In
addition, moisture may collect in the connectors and create electrical connection faults.
IMPORTANT
Before any work is carried out on the high pressure injection system, protect:
–the accessories and timing belts,
–the electrical accessories, (starter, alternator, electric power-assisted steering pump),
–the flywheel surface, to prevent any diesel from running onto the clutch friction plate.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
The cruise control/speed limiter function is inhibited.
Use bornier Elé. 1681 or Elé. 1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
If the fault is declared present, refer to the section of the conformity check on the Cruise control/Speed limiter,
and to the interpretation of statuses:
ET042 Cruise control/speed limiter.
ET415 Deactivation of cruise control/speed limiter.
ET703: Cruise control/speed limiter buttons
Check that by pressing the buttons the statuses change and that, with the ignition switched on, all the values are
correct.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

STATUS 5
ET415
(CONTINUED 2)
STATUS 4
Cancel button pressed
The cruise control/speed limiter function is deactivated each time the suspend button is
pressed.
Status ET415 becomes STATUS 4 while driving when:
- Either the cruise control is active, or
- the speed limiter is active
- and the driver presses the 0 button.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 becomes STATUS 4 without pressing the 0 button, refer to the
interpretation of status ET703 Cruise control/speed limiter buttons and test the R/0
control button located on the steering wheel, to the right.
Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the injection
computer receiving a signal indicating that the brake pedal switch has been pressed.
If status ET415 is STATUS 5, refer to the interpretation of:
- status ET042 Cruise control/Speed limiter,
- status ET703 Cruise control/speed limiter buttons,
- status ET704 Brake contact no. 1,
- and status ET705 Brake contact No 2,
to test the cruise control/speed limiter system components and find the defective
component.
Also check the operation of the accelerator pedal, and check for any faults on the
diagnostic tool relating to this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 changes to STATUS 5, deal with present faults or those stored in the
injection computer.
If the fault is still present, contact Techline.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Carry out these checks if the statuses do not correspond with system operation
programming.
INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control/speed limiter buttons
is pressed. These buttons are located on the steering wheel.
If status ET703 does not display INACTIVE,
- check the condition of the cruise control/speed limiter “+/-” button and the condition of
its connector.
check the condition of the cruise control/speed limiter "R/0" button and the condition of
its connector.
INCREASEStatus ET703 becomes “PLUS” when the cruise control/speed limiter “+” button is
pressed. This button is on the steering wheel, on the left-hand side.
If status ET703 does not display PLUS, check the condition of the cruise control/speed
limiter “+/-” button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane) or 370
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
Measure the resistance of the following connections while pressing the + button
(on the button tracks):
●Connection code 86G, of component 331.
●Connection code 86M of component 331.
If the resistance is not approximately 300 Ω, check the continuity of the connection when
the button is in the rest position.
If there is continuity, replace the +/- control button.
If there is a repair method (See Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic tool

DECREASEStatus ET703 becomes MINUS when the cruise control/speed limiter - button is pressed.
This button is on the steering wheel, on the left-hand side.
If status ET703 does not change to MINUS, check the condition of the cruise control/

Measure the resistance of the following connection whilst pressing the - button (on
the button tracks):
●Connection code 86G, of component 331.
●Connection code 86M of component 331.
If the resistance is not approximately 100 Ω, check the continuity of the connection when
the button is in the rest position.
If there is continuity, replace the +/- control button.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring
SUSPENDStatus ET703 becomes “SUSPEND” when the cruise control/speed limiter “0” button is
pressed. This button is located on the steering wheel, to the right.
If status ET703 does not change to SUSPEND, check the condition of the cruise control/
speed limiter “R/0” button, and the condition of its connector.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see 364 (Mégane) or 370

Measure the resistance of the following connection whilst pressing the 0 button
(on the button tracks):
●Connection code 86G, of component 331.
●Connection code 86M of component 331.
If the resistance is not approximately 0Ω, replace the R/0 control button.
If there is continuity, replace the R/0 control button.
If there is a repair method (See Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
