ET004
AC AUTHORISED
STATUS DEFINITION"YES": This status shows that the air conditioning is authorised.
"NO": This status shows that the air conditioning is not authorised.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check: Engine switched off and ignition on or engine running, engine coolant temperature
>80°C
YES
The air conditioning authorisation only changes to "YES" if:
– the air conditioning request has been made by the driver (air conditioning switch in
AC position with minimum ventilation),
– the engine is not under full load,
– the air conditioning system is not faulty.
NOStatus ET004 remains at "NO" under the following conditions:
– Vehicle stopped with the ignition on,
– faults present in the air conditioning circuit,
– no air conditioning request made by the driver,
– engine under full load.
If status ET004 remains "NO" then the air conditioning should be authorised, check:
– that the air conditioning compressor is activated correctly,
– the air conditioning system feed fuses,
– the presence of refrigerant in the air conditioning circuit.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

LOW SPEED GMV CONTROL
STATUS DEFINITION"ACTIVE": The status indicates that the low-speed fan request is active.
"INACTIVE": The status indicates that the low-speed fan request is not active.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
NOTE:
Status ET022 Low-speed fan request changes status.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80 °C

FAST IDLE SPEED REQUEST
STATUS DEFINITION"ACTIVE": This status indicates that the fast idle speed request is active.
"INACTIVE": This status indicates that the fast idle speed request is inactive.
NOTESSpecial notes:
The idle speed setpoint is dependent on:
– the coolant temperature,
– the emission control programs,
– air conditioning requirements,
– the electrical consumers,
– battery voltage.
– the gear engaged.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
ACTIVE
Status is "ACTIVE" when there is an engine load:
●inconsistency between the positions of the brake and accelerator pedals,
●coolant temperature <80 °C or >89 °C,
●heating and air conditioning system activated,
●with electrical consumers,
●the battery voltage is incorrect.
INACTIVEStatus is "INACTIVE" when there is no engine load:
●coolant temperature = 80 °C,
●heating and air conditioning system deactivated,

IMPACT DETECTED
STATUS DEFINITION"YES": This status indicates that the airbag computer has detected an impact.
"NO": This status indicates that the airbag computer has not detected an impact.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
YES
If the vehicle has had an accident, the injection computer receives the impact signal via
the multiplex network and may switch off the ignition.
Switch off the ignition for 10 seconds, then switch it back on, so the engine can be
restarted.
Test the multiplex network (see88B, Multiplexing), and deal with any faults.
NOIn normal operating conditions, status ET077 is NO if the injection computer has
received no impact signal.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

ET088
REQUEST TO START COMPRESSOR
STATUS DEFINITION"ACTIVE": This status indicates that the compressor activation request is active.
"INACTIVE": This status indicates that the compressor activation request is not active.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
ACTIVE
Status ET088 becomes ACTIVE if there has been a request for air conditioning (press
on AC or AUTO button, with maximum cold request) and 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 compressor activation.
If the injection computer authorises compressor switch-on, the injection computer
sends the compressor switch-on request to the UPC and status ET088 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 compressor switch-on, it sends the request for
compressor switch-on to the UPC and status ET088 becomes "ACTIVE".
If there has been no compressor switch-on request and status ET088 remains
"ACTIVE", see62A, Air conditioning.
Note: Compressor operation is only authorised when the engine is running.
Compressor activation is commanded by the UPC.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

INACTIVE
Status ET088 is "INACTIVE" when no air conditioning request has been made. When
compressor switch-on has not been authorised (ET004 "AC authorised" is "NO") or
when the driver switches the heating and air conditioning system off.
If there is a compressor switch-on request and status ET088 remains "INACTIVE",
see62A, Air conditioning.
Note: Compressor operation is only authorised when the engine is running.
Compressor activation is commanded by the UPC.

INACTIVE: This status indicates that the clutch pedal is released.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
"INACTIVE"
Check the condition and the fitting of the clutch pedal switch (see MR 392, 385, 364,
370 and 417 Mechanical, 37A, Mechanical component controls, Clutch pedal
position sensor: Removal - Refitting).
Remove the clutch pedal switch and check the insulation between connections MAM
and 86D (for Mégane II ph 2, Scénic II ph2 and Kangoo II) and between connections
MAS and 86D (for Clio III and Modus) of component675 with the switch in the rest
position.
– Repeat this operation with the switch engaged, and check the continuity between
the two connections.
If these two checks are not correct, replace the clutch pedal switch (see MR 392, 385,
364, 370 and 417 Mechanical, 37A, Mechanical component controls, Clutch pedal
position sensor: Removal - Refitting).
Then check the continuity and absence of interference resistance of the following
connection:
– connection code 86D between components 120 and 675.
– Check that the earth is correct on connectionMAM (for Mégane II ph 2, Scénic II
ph2 and Kangoo II) or on connectionMAS (for Clio III and Modus) of
component675.
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 it.
