ET004AC 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 parameters do not correspond with the system operation
programming.
Conformity check: Engine stopped and ignition on, or engine running at idle speed, and engine coolant
temperature > 80˚C.
YES or NOIf air conditioning is authorised or if the compressor is actuated, (see 62A, Heating
system, 62B, Climate control or 62C, Manual air conditioning).
Sensor electrical conformity
"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.

ET004
CONTINUED
"NO"
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 feed fuses,
–the presence of refrigerant in the air conditioning circuit,
If the fault is still present, check the air conditioning computer faults
(see 62A, Heating, 62B, Climate control or 62C, Manual air conditioning).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

ET088REQUEST TO START COMPRESSOR
STATUS
DEFINITIONACTIVE: This status indicates that the compressor is engaged.
INACTIVE: This status indicates that the compressor is not engaged.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Engine running, engine coolant temperature > 80˚C
"ACTIVE"The air conditioning request has been made by the driver when pressing one of the
air conditioning controls (Auto or AC).
Status ET088 becomes ACTIVE and the computer authorises or does not authorise
air conditioning depending on the operating conditions.
If status ET088 does not become ACTIVE when the control button is pressed, refer
to the air conditioning fault finding note (see 62A, Heating system, 62B, Climate
control or 62C, Manual air conditioning).
Note: Compressor operation is only authorised when the engine is running.
Conformity check with engine stopped and ignition on.
"INACTIVE"When the driver deactivates the air conditioning, status ET088 must become
INACTIVE.
If it does not, refer to the air conditioning fault finding note (see 62A, Heating system,
62B, Climate control or 62C, Manual air conditioning).
Note: Compressor operation is only authorised when the engine is running.

AC180AIR CONDITIONING COMPRESSOR RELAY CONTROL
NOTESSpecial notes:
There must be no present or stored faults.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III
or MODUS.
Check the condition of the connectors of the air conditioning compressor clutch relay (component code 584) and
of the engine management computer (component code 120).
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
With the ignition, check for + 12 V on connection 3FB of the air conditioning compressor clutch relay and the
earthing of connection 38K on the injection computer connector.
Use the universal bornier to check the insulation and continuity of the following connections:
●3FB between components 584 and 238,
●38K between components 584 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the control still does not operate, run a diagnostic check on the Heating system.
(see 62A, Heating, 62B, Climate control or 62C, Manual air conditioning).

AFTER REPAIRIf the throttle valve has been replaced, reinitialise the RZ005 programming.
Carry out a road test, then check with the diagnostic tool.
