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.
