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
ACTIVE
The injection computer requests the activation of the low speed GMV when:
– the engine coolant temperature is above 96 °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 fan request" becomes "ACTIVE"
INACTIVEThe low-speed engine fan assembly stops when:
– the engine coolant temperature is below 94 °C,
– no fault which could cause engine overheating is present in the injection
system.
– the air conditioning is not switched on by the driver.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

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,
●without electrical consumers,
●the battery voltage is correct.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

ET077
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.

NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Heating and air conditioning is present depending on the vehicle's equipment level.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature

YES or NO, depending on the vehicle equipment.

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.
