–coolant temperature < 80
°C or > 89 °C,
–heating and air conditioning system deactivated,
–with electrical consumers,
–the battery voltage is incorrect.

ET042CRUISE CONTROL/SPEED LIMITER
STATUS DEFINITIONNOT DETECTED: This status indicates that the cruise control or speed limiter function
is not present on the vehicle.
INACTIVE: This status indicates that the cruise control/speed limiter main On/Off switch
is in the rest (or neutral) position.
LIMITER: This status indicates that the driver has used the main switch to select the
speed limiter.
CRUISE CONTROL: This status indicates that the driver has used the main switch to
select the cruise control.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system programming
functions.
Conformity check: Engine stopped, ignition on or engine running.
NOT DETECTED If 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 multiplex network test page on the Clip application. 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 vehicle's owner has not had
the cruise control/speed limiter function disabled in the past. Contact the Techline.

INACTIVE When the main switch is in rest position (or neutral), status ET042 is INACTIVE.
If CRUISE CONTROL or SPEED LIMITER appears despite the main switch being in the
rest (or neutral) position, carry out the following operations:
For Mégane II and Scénic II:
Check the connections of the cruise control/speed limiter main switch, component code
1081 (Mégane II) or 1546 (Scénic II).
If the connector is faulty and there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for repair), repair the connector,
otherwise replace the wiring.
Check for + 12 V after ignition on the main switch connector.
●Connection code AP43, component 1081 (Mégane II) or 1546 (Scénic II).
If the connection is faulty and there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise
replace it.
Disconnect the main switch and with it in the rest position, check the insulation between:
●Connection codes AP43 and 3FX, component 1081 (Mégane II) or 1546
(Scénic II).
●Connection codes AP43 and 3PD, component 1081 (Mégane II) or 1546
(Scénic II).
Check the continuity between connections AP43 and 3PD of component 1081
(Mégane II) or 1546 (Scénic II) at speed limiter position.
Check the continuity between connections AP43 and 3FX of component 1081
(Mégane II) or 1546 (Scénic II) at cruise control position.
If the checks are incorrect, replace the switch, component code 1081 (Mégane II) or
1546 (Scénic II).
Check the insulation, continuity and the absence of interference resistance on the
following connections:
●3FX between components 120 and 1081 (Mégane II) or 1546 (Scénic II),
●3PD between components 120 and 1081 (Mégane II) or 1546 (Scénic II),
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.
Check the connections of the engine management computer, component code 120.
If the connector is faulty and there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for repair), repair the connector,
otherwise replace the wiring.
