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.

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.

INACTIVEWhen the main switch is in rest position (or neutral), status ET042 is "INACTIVE".
If "CRUISE CONTROL" or "SPEED LIMITER" appears despite the main button being in
the rest position (or neutral), carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for + 12 V APC on the main switch connector.
–Connection code AP43 of component 1081 (Mégane II)
–Connection code AP43 of component 1546 (Scénic II)
Disconnect the main switch and with it in the rest position, check the insulation between:
–Connection codes AP43 and 3FX of component 1081 (Mégane II)
–Connection codes AP43 and 3PD of component 1081 (Mégane II)
–Connection codes AP43 and 3FX of component 1546 (Scénic II)
–Connection codes AP43 and 3PD of component 1546 (Scénic II)
Check the continuity between connections AP43 and 3PD of component 1081
(Mégane II) and component 1546 (Scénic II) in speed limiter position.
Check the continuity between connections AP43 and 3FX of component 1081
(Mégane II) and component 1546 (Scénic II) in cruise control position.
If these checks are not in order, replace the switch.
Check the insulation, continuity and the absence of interference resistance on the
following connections:
–Connection code 3FX,
–connection code 3PD.
Between components 1081 and 120 (Mégane II)
Between components 1546 and 120 (Scénic II)
Also check the engine management computer connectors.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Repair precautions), repair the wiring, otherwise replace it.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

Check for + 12 V after ignition feed on the main switch connector.
●Connection code AP43 of component 1081 (Mégane II).
●Connection code AP43 of component 1546 (Scénic II).
Disconnect the main switch and with it in the rest position, check the insulation between:

(Mégane II) and component 1546 (Scénic II) in speed limiter position.
–Check the continuity between connections AP43 and 3FX of component 1081
(Mégane II) and component 1546 (Scénic II) in cruise control position.
If these checks show incorrect values, replace the main switch.
