CHECK COOLING FAN 2
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOTE:
Status ET015 GMV 2 test and status ET021 High speed GMV request change their status at the same time.
RUNNING
The engine fan assembly can be supplied when:
–the engine coolant temperature is above 99 ˚C.
–the injection computer has system faults that could lead to the engine overheating.
When the high speed fan is supplied:
–status ET015 GMV 2 test becomes RUNNING and status ET021 High speed GMV
request becomes ACTIVE.
The high-speed engine fan assembly stops when:
–the engine coolant temperature is below 99 ˚C;
IMPORTANTWARNING
If the UPC does not detect the injection computer frames, the low speed engine
fan is supplied until the battery is completely discharged.
In the event that the low-speed engine fan assembly is faulty, the high-speed
engine fan assembly will then be activated.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

ACTIVE
The injection computer requests the activation of the high speed GMV when:
–the engine coolant temperature is above 99 ˚C.
–the injection computer has system faults that could lead to the engine overheating.
When the high speed fan is supplied:
–status ET021 High speed GMV request becomes RUNNING and status ET015
GMV 2 test becomes ACTIVE.
The high-speed engine fan assembly stops when:
–the engine coolant temperature is below 99 ˚C;
–no fault which could cause engine overheating is present in the injection
system.
IMPORTANTWARNING
If the UPC does not detect the injection computer frames, the low speed engine
fan is supplied until the battery is completely discharged.
In the event that the low-speed engine fan assembly is faulty, the high-speed
engine fan assembly will then be activated.

NOTE:
Status ET022 Low speed GMV request and status ET014 GMV 1 test change their status at the same time.
ACTIVE
The injection computer requests the activation of the low speed GMV when:
–the engine coolant temperature is above 89 ˚C;
–the injection computer has system faults that could lead to the engine overheating,
–the air conditioning is switched on by the driver.
When the high speed fan is supplied:
–status ET022 Low speed GMV request becomes ACTIVE and status ET014 GMV
1 test becomes RUNNING.
The low-speed engine fan assembly stops when:
–the engine coolant temperature is below 89 ˚C;
–no fault which could cause engine overheating is present in the injection
system.
–the air conditioning is not switched on by the driver.

NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
STOPPED
Status ET038 is STOPPED if the engine ignition is on but there has been no starter
operation.
Status ET038 is “starting” when the engine is in starting phase.
Status ET038 is RUNNING if the engine has started.
Status ET038 is STALLED when the engine has stalled.
The vehicle will still be on + after ignition feed.

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.
