Remove the clutch pedal switch, check the insulation between connections M and
86D of component 675, with the switch in the rest position.
– Repeat this operation with the switch engaged, and check the continuity between
the two connections.
If these 2 checks are faulty, replace the switch.
Then check the continuity and absence of interference resistance of the following
connection:
– connection code 86D between components 120 and 675.
Make sure that the earth is compliant on connection M of component 675.
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 the wiring.
ACTIVECheck the condition and fitting of the clutch pedal switch.
Remove the clutch pedal switch, check the insulation between connections M and

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 frontal airbag (see MR 364 Mégane,
MR370 Scénic, Mechanical, 88C, Airbag and pretensioners, Driver's front
airbag, Removal - Refitting).
If status ET703 does not display INACTIVE,
– check the status of the cruise control/speed limiter +/- button and the condition of its
connector.
– check the status of the cruise control/speed limiter R/0 button and the condition of
its connector.
Repair if necessary.
INCREASEStatus ET703 becomes INCREASE when the + button of the cruise control/speed
limiter is pressed. This button is on the steering wheel, on the left-hand side.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's frontal airbag (see MR 364 Mégane,
MR370 Scénic, Mechanical, 88C, Airbag and pretensioners, Driver's front
airbag, Removal - Refitting)
If status ET703 does not display INCREASE, check the status of the +/- button of the
cruise control/speed limiter and the status of its connector. Repair if necessary.
Measure the resistance on 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 not pressed.
If there is continuity, replace the +/- control button.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

PARAMETER
DEFINITIONThis parameter indicates the engine's speed of rotation with air conditioning in rpm.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on
Indicates the engine's speed of rotation with air-conditioning in rpm.
PR035 = 0 rpm.
Conformity check with engine running, engine coolant temperature > 80°C
The speed requested by the air-conditioning is increased and varies around 850 rpm.

PR873OIL OXIDATION SIGNAL
PARAMETER
DEFINITIONThis parameter indicates the distance of the vehicle when the oil dilution threshold is
reached.
NOTESOnly apply the interpretation of this parameter if the OCS (oil control system)
program is activated on the instrument panel. On the instrument panel computer,
check the configuration reading LC106 OCS: WITH
This parameter is not operational in Vdiag44
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C, without electrical consumers
The oil condition is calculated by the oxidation program in the injection computer, according to the number of
engine revolutions.
When this count reaches a certain threshold before the end of the oil service period, the injection computer sends
a signal to the instrument panel, which will display service due. Parameter PR873 corresponds to the vehicle
mileage at the time this signal is sent.
Then the instrument panel computer deducts 900 miles (1500 km) before displaying the message Service
required.
IMPORTANT
When the message Service required appears on the instrument panel, the customer must arrange an oil change
within the remaining 900 miles (1500 km).

AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check with the diagnostic tool.

SC001WRITE SAVED DATA
NOTESTo use this command, first save the data with the SC003 Save computer data
command.
The writing is carried out after the computer has been reprogrammed or replaced.
Ignition on and engine stopped.
Validating this command writes the data saved using command
SC003 Save computer data.
The data is as follows:
– injector codes,
– the egr valve data programming;
options available on the vehicle and managed by the computer (e.g. air conditioning);
This data will configure the computer and will prevent:
– engine malfunction after (re)programming or replacing the computer;
– faulty interpretation of information provided by the CLIP tool.
