AC AUTHORISED
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
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 or AUTO position with minimum ventilation),
–the engine is not under full load,
–the air conditioning system is not faulty.
Status 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 supply fuses,
–the presence of refrigerant in the air conditioning circuit,
–that the refrigerant fluid pressure value is consistent at idle speed.
If the fault is still present, check the climate control computer faults (see 62C, Air
conditioning).
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOTE:
Status ET014 test and status ET022 GMV1 low speed request change their status at the same time.
RUNNING
The low-speed engine fan unit is supplied in three scenarios:
–the engine coolant temperature is above 89 ˚C;
–the air conditioning is operating
–the injection computer has system faults that could lead to the engine overheating.
When the low-speed engine fan is supplied:
–status ET014 GMV 1 test becomes RUNNING status ET022 Low speed GMV
request becomes ACTIVE.
If the low speed GMV does not work (see 87G, engine compartment connection unit).
The low-speed engine fan assembly stops when:
–the engine coolant temperature is below 89 ˚C;
–the air conditioning is not switched on by the driver.
STOPPED
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.

NOTESSpecial notes:

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.
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.

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.

WRITE SAVED DATA
NOTESAll data must be saved with command SC003 SAVE COMPUTER DATA for this
command to be run.
Writing is carried out after the computer has been reprogrammed or replaced.
Validating this command writes the data saved using command SC003 SAVE COMPUTER DATA.
The data is as follows:
–vehicle idle speed,
–injector calibration codes (if the vehicle is fitted with IMA),
–programming of exhaust gas recirculation valve data,
–options available on the vehicle and managed by the computer (E.g. air conditioning).
This data configures the computer and prevents:
–engine malfunction after reprogramming or replacing the computer,
–incorrect interpretation of the information provided by the CLIP diagnostic tool.
