CRUISE CONTROL/SPEED LIMITER
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOT DETECTEDIf the vehicle is not fitted with cruise control/speed limiter function buttons, status ET042
is permanently NOT DETECTED. This confirms that the cruise control/speed limiter
function is not present on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons, the main switch
is in rest (or neutral) position and the injection computer has just been programmed or
reprogrammed, then status ET042 is NOT DETECTED.
To activate the cruise control or speed limiter function, press the main switch in the cruise
control position and then in the speed limiter position.
Return to rest position.
The tool displays status ET042: INACTIVE.
If not, several steps must be checked:
1 - Return to the page about testing the multiplex network with the CLIP program.
Repeat the multiplex network test. Re-establish dialogue with the injection computer.
Check status ET042. If ET042 is INACTIVE, the injection computer has detected the
various positions of the main switch. The cruise control/speed limiter is active.
2 - If status ET042 is still NOT DETECTED, check that the owner of the vehicle has not,
sometime in the past, asked for the cruise control/speed limiter function to be
deactivated. Contact the 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

ENTER INJECTOR CODES
NOTESThis command should be run after the injectors have been replaced and only if the
vehicle has been configured with IMA.
(ET104 USE OF INJECTOR CODES to YES).
If this command is not performed, the DF276 INJECTOR CODE PROGRAMMING
fault will be present.
WARNING
The letters J and Q, and figures 0 and 9 are not used in IMA coding.
If these characters are used the entry will be invalid.
Cylinder no. 1 is the cylinder located at the engine flywheel end.
Procedure to be followed:
–Read the 6-character alphanumeric codes etched on the upper section of the injector bodies.
–Use command SC002.
–Select the cylinder number for the cylinder concerned in the Desired, column, then confirm.
–Enter the injector code displayed for the cylinder.
–Enter the new codes for each cylinder, then confirm.
–When the command is completed, the modified codes appear in the Current column.
–Check that the codes correspond to those read earlier.
–If the codes entered appear in neither the Current column nor the Desired column, check the codes read and
make sure the data has been entered correctly,
The possible confusions are:
digit "1" with the letter "I"
figure 8 with the letter B
figure 5 with the letter S
–Exit fault finding mode.
–Switch off the ignition and wait for 1 min.
–Switch the ignition back on and check for faults.
–DF276 INJECTOR CODE PROGRAMMING should be stored.
If fault DF276 is still present, the command has not been performed correctly.
Start the procedure again and follow the instructions.
If the codes are still not recognised, check whether the computer's standby has been correctly set:
Switch off the ignition and wait for 1 min.
If the warning light flashes when the ignition is switched off, the computer has not been put on standby and the
command will be ignored.
If all these checks still do not enable the command to be confirmed, contact the Techline.

Turbocharger control circuit check (continued)
4) Turbocharger operation check:
a) Connect a vacuum pump to the hose connected to the turbocharger control diaphragm.
Apply a negative pressure of 800 ± 100 mbar:
If there is a leak, replace the turbocharger (diaphragm included).
b) Check the control rod movement and setting (see MR 364, Mechanics, 12B, Turbocharging).
If the control rod is sticking, replace the turbocharger.
c) Engine cold and stopped:
Remove the turbocharger inlet duct and check that the compressor turns freely on the axis.
d) If the fault persists:
Check that the exhaust manifold is not leaking.
Check that the exhaust is not blocked.
Carry out the necessary repairs.
5) Computer output stage check: (solenoid valve connected).
This operation can only be carried out if the checks indicated in step no. 2 are not conclusive.
Either with the voltmeter: Connect the voltmeter earth lead on track 2 of the solenoid valve and the positive
lead on track 1.
Clear any solenoid valve fault then run command AC004:
●The voltmeter should display ten cycles of two successive voltages ~ = battery voltage X opening cycle ratio*
in process.
that is: ~ 2.5 V (opening cyclic ratio* of 20%) then ~ 8.7 V (opening cyclic ratio* of 70%).
Or with the oscilloscope (at 5 V range/division and 1 ms/div time base): Connect the earth lead of the
oscilloscope to the battery earth and the positive test pin to track 2 of the solenoid valve.
Clear any solenoid valve faults, then run command AC004:
●the oscilloscope should display a square wave signal of 12.5 V in amplitude at a frequency of 140 Hz
(with an opening cyclic ratio* passing from ~ 20 to ~ 70%).
If the measurement is correct, replace the solenoid valve.
If the measurement does not show any control or continuous voltage, contact the Techline.
