STATUS
DEFINITIONThis status indicates that the low-speed fan assembly relay is being actuated (ACTIVE)
or not (INACTIVE).
NOTESSpecial notes:
–Perform these checks if the parameters correspond with the system operation
programming.
–If the vehicle is equipped with air conditioning, the engine cooling fan will run at 1
st
speed as soon as the air conditioning compressor is activated.
There should be no fault detected on the coolant temperature sensor circuit when this
fault finding procedure is being carried out.
Conformity check with engine stopped and ignition on.
INACTIVEEngine cold and air conditioning switched off
In the event of a fault, consult the interpretation of fault DF559 Low-speed fan
assembly control.
Conformity check with the engine running and engine coolant temperature > 80˚C
ACTIVE
INACTIVEINACTIVE or ACTIVE, according to the engine temperature and the air conditioning

ET603AIR CONDITIONING COMPRESSOR RELAY CONTROL CIRCUIT
STATUS
DEFINITIONACTIVE: This status indicates that the air conditioning compressor relay control
is active.
INACTIVE: This status indicates that the air conditioning compressor relay control
is inactive.
NOTESThere must be no present or stored faults.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
"ACTIVE"
or
"INACTIVE"This status becomes ACTIVE when the air conditioning compressor is activated by
the driver.
In the event of a fault, apply the interpretation of DF1072 Air conditioning
compressor control.

ET674REFRIGERANT PRESSURE–Too low
–Correct
–Unavailable
STATUS
DEFINITIONTOO LOW: this status indicates that the refrigerant pressure is too low.
CORRECT: this status indicates that the refrigerant pressure is correct.
UNAVAILABLE: this status indicates that the refrigerant pressure is unavailable.
NOTESDeal with DF232 Refrigerant pressure sensor circuit first.
There must be no present or stored faults.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
TOO LOW
or
CORRECT
or
"UNAVAILABLE"The purpose of this status is to check that the circuit is correctly charged with gas.
It becomes active when the air conditioning is detected as being connected and there
are no faults present.
The result of this status is:
–Too low: Pressure below 2 bar.
–Correct: Pressure above 2 bar.
–Unavailable: Cannot perform test.

PR090IDLE SPEED REGULATION PROGRAMMING VALUE
PARAMETER
DEFINITIONThis parameter indicates the idle speed regulation programming value as a %.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
PR090 is a stored parameter designed to "program" dispersion and engine ageing for the idle speed regulator.
The programming is carried out only when the engine is idle and warm, and no electrical consumer
(air conditioning, fan assembly, power assisted steering) is operating. Therefore it adjusts slowly.
