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.

Deal with DF001 Coolant temperature sensor circuit first.
Check the consistency of PR064 Coolant temperature.
If this status is inconsistent:
Disconnect the battery.
Check the condition of the engine management computer connector (component code 120).
For NEW TWINGO or E33:
Check the condition of the air conditioning control unit connector (component code 419).
If the connector(s) is(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.
Use the universal bornier to check the insulation and continuity of the following connections:
●133B between components 120 and 419,
●133C between components 120 and 419.
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 fault is still present, carry out fault finding on the UCH system (see 87B, Passenger compartment
connection unit).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
Repeat the conformity check from the start.

ET079AIR CONDITIONING PRESENT
STATUS
DEFINITIONYES: This status indicates that air conditioning is present on the vehicle.
NO: This status indicates that air conditioning is not present on the vehicle.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
The heating and air conditioning system is present depending on the vehicle's
equipment level.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C

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.
