AC AUTHORISED
STATUS DEFINITIONYES, this status indicates that the air conditioning is active.
NO, this status indicates that the air conditioning is inactive.
NOTESSpecial notes
Only perform these tests if the statuses do not correspond with the system
programming functions.
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 or AUTO position with minimum ventilation),
– the engine is not under full load,
– the air conditioning system is not faulty.
Conformity check with engine stopped and ignition on
NOStatus ET004 remains 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,
– that the refrigerant fluid pressure value is consistent at idle speed.
If the fault is still present, check the air conditioning computer faults (see62C, Air
conditioning).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

the coil, and connect a voltmeter as follows:
Positive terminal to the +12 V battery.
Negative terminal to connection 3JN of the low-speed fan assembly relay mounting.
Clear the fault and run command AC038
If the voltmeter indicates the battery voltage (three 2-second ON-OFF cycles), replace the relay.
If the voltmeter does not show the battery voltage (three 2 second ON-OFF cycles), contact the techline.
If the low speed fan assembly relay operates when command AC038, is run, but there is still a fan assembly
activation fault, use the wiring diagram to check the following:
– the conformity of the fan assembly maxi-fuse.
