Remove the clutch pedal switch, check the insulation between tracks 1 and 2 in rest
position.
Repeat this operation with the switch pressed and check the continuity between tracks
1 and 2.
If these two checks are not in order, replace the switch.
Then check the continuity and absence of interference resistance of the following
connection:
Injection computer black 32-track
connector A, track C4Track 1 clutch connector
Check for earth on track 2 of the clutch switch connector.
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.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic

NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control/speed limiter buttons
are pressed. These buttons are located on the steering wheel.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane II) or 372
(Scénic II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,
Removal - Refitting).
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.
Repair if necessary.
INCREASEStatus ET703 becomes INCREASE 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 INCREASE, 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 372
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting)
Measure the resistance on the following connections while pressing the + button
(on the button tracks):
– Connection code86G of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 300 Ω, check the continuity of the connection for
the button 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 it.

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 it.
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 MR 364 (Mégane II) or 370
(Scénic II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,

Measure the resistance of the following connection whilst pressing the 0 button
(on the button tracks):
– Connection code86G of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 0 Ω, 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 it.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

REFRIGERANT PRESSURE
NOTESThere must be no present or stored faults.
Perform this fault finding procedure after an inconsistency is displayed in the
Parameters menu or after a customer complaint (no air conditioning, etc.).
Step 1
– Start the engine, switch on the air conditioning and increase the engine speed to 1,500 rpm:
– Display PR037 Refrigerant pressure in the Cold loop function on the diagnostic tool:
If the pressure is greater than ~27bar, go to step 2.
If the pressure does not rise, or remains below normal:
– Ensure that the air conditioning compressor and the relay are operating correctly.
– Check the conformity of the refrigerant pressure sensor by comparing* the value displayed by the tool (PR192)
with the reading given by the charging station high pressure gauge.
If the pressure difference = ±1.5bar, (or 1500 mbar):
Check the continuity and the absence of interference resistance on the connections between:
Injection computer, grey 24-track connector C,
track C3Track A of the refrigerant pressure sensor
Injection computer, brown 48-track connector
B, track F1Track C of the refrigerant pressure sensor
Injection computer, brown 48-track connector
B, track F3Track B of the refrigerant pressure sensor
If these connections are not faulty, replace the refrigerant pressure sensor.
If there is no difference, the refrigerant pressure sensor is correct: go to step 2.
Step 2
– Perform fault finding on the air conditioning.
*Note:
The diagnostic tool displays the absolute pressure, the charging station high pressure gauge displays the relative
pressure.
The normal difference between the two is equal to atmospheric pressure, i.e. ~1,000mbar.
AFTER REPAIRRepeat the conformity check from the start.

FUEL TEMPERATURE
NOTESThere must be no present or stored faults.
NOTE
In the event of a relatively low outside temperature, the difference between the
fuel temperature and the engine temperature after cold starting may be greater
than 30 °C.
Check in the Fuel circuit tab in PR063 Fuel temperature that the value displayed is not the recovery value 100 °C.
If it is, check the fuel temperature sensor:
Check that the fuel temperature sensor is in good condition:
Repair if necessary.
Check the continuity and the absence of interference resistance on the following lines:
Brown 48-track connector B, track H2 Track 1 fuel temperature sensor
Grey 32-track connector C, track F1 Track 2 fuel temperature sensor
If the temperature read is inconsistent, check that the sensor follows the resistance as a function of temperature
calibration curve (NTC) correctly.
Replace the fuel pressure and temperature sensor if the resistance is not:
2,051 ± 123Ω at 25 °C
810 ± 47Ω at 50 °C
309 ± 17Ω at 80 °C
Replace the fuel temperature sensor if it is incorrect (an incorrect sensor is often the result of an electric shock).
AFTER REPAIRRepeat the conformity check from the start.

COOLANT TEMPERATURE
NOTESNo fault should be present or stored:
Perform this fault finding procedure after noting an inconsistency in the Parameters
menu.
Display the PR064 Coolant temperature and check that the value displayed is not recovery value -30°C.
If this is the case, check the coolant temperature sensor:
Check the condition of the coolant temperature sensor connections.
Repair if necessary.
Check for the absence of interference resistance on the following lines:
Brown 48-track connector B, track F2 Track 3 coolant temperature sensor
Brown 48-track connector B, track H1 Track 2 coolant temperature sensor
If the temperature read is inconsistent, check that the sensor follows the resistance as a function of temperature
calibration curve (NTC) correctly.
Replace the air temperature and pressure sensor if the resistance is not:
2,252Ω ± 112Ω at 25 °C
811Ω ±39Ω at 50 °C
283Ω ±8Ω at 80 °C
Replace the coolant temperature sensor if the values read do not correspond to the ones above.
AFTER REPAIRRepeat the conformity check from the start.
