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.

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.

NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
AUTHORISED
Starting the vehicle is authorised when the UCH authorises starting.
Status ET076 changes to AUTHORISED if the vehicle cards are recognised and the
engine immobiliser is inactive.
If the card is not recognised by the UCH, starting the vehicle is prohibited.
Status ET076 is PROHIBITED and the vehicle cannot be started.
Run fault finding on the UCH (see 87B, Passenger compartment connection unit).

IMPACT DETECTED
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
If the vehicle has been involved in an accident, the injection computer receives the
impact signal via the multiplex network and may switch off the ignition. Status ET077 is
YES.
Switch off the ignition for 1 minute then switch on the ignition again so the engine can be
started.
Carry out a multiplex network test and deal with any faults.
Under normal operating conditions, status ET077 is NO when the computer has received
no impact signal.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

ET088
REQUEST TO START COMPRESSOR
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
ACTIVE
Status ET088 becomes ACTIVE if there has been a request for air conditioning (press
the AC or AUTO button, with maximum cold) and if status ET004 is YES.
The selection is made on the air conditioning control panel, the request for air
conditioning is transmitted to the UCH which in turn transmits the request to the injection
computer which either authorises or does not authorise the compressor to switch on. If
the injection computer authorises the compressor to switch on, its sends the
compressor on request to the UPC and status ET088 COMPRESSOR ON REQUEST
becomes ACTIVE (Climate control).
If the vehicle is equipped with manual air conditioning, the air conditioning request is
transmitted from the air conditioning control panel to the UCH which then accepts or does
not accept the air conditioning compressor coming on depending on the operating status
of the passenger compartment fan. When the request has been accepted, the request
to switch on the compressor is transmitted to the injection computer which either
authorises or does not authorise the compressor to start.
If the injection computer authorises the compressor to switch on, its sends the
compressor on request to the UPC and status ET088 COMPRESSOR ON REQUEST
becomes ACTIVE.
If there has been no compressor on request and status ET088 remains ACTIVE
(see 62A, Air conditioning).
Note:
Switching on the compressor is only authorised when the engine is running.
Switching on the compressor is ultimately controlled the UPC.
Status ET088 is INACTIVE when there has been no air conditioning request and
when the compressor has not been authorised to come on (ET004 is NO or when
the driver turns off the air conditioning).
If there has been no compressor on request and status ET088 remains INACTIVE (see
62A, Air conditioning).
Note:
Switching on the compressor is only authorised when the engine is running.
Switching on the compressor is ultimately controlled the UPC.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

INJECTOR CODE USE
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
Status ET104 is YES if the IMA option (individual injector correction) is activated in
the injection computer.
All the injectors have IMA codes etched on the bakelite body, but not all computers
use them.
In the case of a computer configured with the IMA option, the injector codes must be
entered into the injection computer in the following scenarios:
–when one or more injectors is replaced,
–when the injection computer is replaced,
–when the injection computer is reprogrammed.
If the injector codes are not programmed after these operations, fault DF276
Injector code programming will be present, and the engine will operate in defect
mode.
In this case, run command SC002 Enter injector codes, applying the procedure
described in the interpretation of this command.
Status ET104 is NO if the computer is not configured to interpret the IMA codes
(individual injector correction).
In this case, run command SC002 Enter injector codes, applying the procedure
described in the interpretation of this command.
Status ET104 is FAULTY if the computer does not have IMA codes in the memory.
Fault DF276 Injector code programming is present and the engine runs in defect
mode.
Run command SC002 Enter injector codes applying the procedure described in the
interpretation of this command.
If at the end of the procedure status ET104 remains FAULTY, contact Techline.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

RESISTORS
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
Depending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required)
Status ET111 becomes YES when the number of activated passenger compartment
heating resistors is set by the injection computer.
Depending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required) Status ET111
becomes NO when the number of activated passenger compartment heating resistors
can be freely controlled by the UCH.
