NOTESConditions for applying the fault finding procedure to stored faults
The fault is declared present when the engine is running.
Special notes:
CO or CC.1: Not possible to control the air conditioning and the customer is complaining
that driving comfort is reduced.
CO: No impact on the system.
CC.0: The compressor is still active, risk of irreversible damage to the compressor (loss
of capacity). The customer is complaining that the air conditioning is operating
continuously.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III, or
MODUS.
Check the condition of the UPC connectors, component code 1337.
Check the condition of the engine management computer connector, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Run a test on the UPC computer (see 87G, Engine compartment connection unit).
Run command AC180 Air conditioning compressor relay control and check for + 12 V on connection 38R of
the air conditioning compressor clutch, component code 171.
If the fault is still present, contact the Techline.

AFTER REPAIRFollow the instructions to confirm repair:
–If the fault is present, continue to deal with the fault.
–If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.

Check the condition of the air conditioning compressor clutch relay connector, component code 584.
Check the condition of the engine management computer connector, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Run command AC180 Air conditioning compressor relay control
If the command does not work, with the ignition on, check for + 12 V on connection 3FB of the air conditioning
compressor clutch relay, component code 584 and for the earthing of connection 38K of the injection computer
connector, component code 120.
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 fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair:

STATUS
DEFINITIONPRESENT: This status indicates that the + after ignition feed is active.
ABSENT: This status indicates that the + after ignition feed is not active.
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.
"PRESENT"
Ignition on and engine running warm at idle speed with the + after ignition feed
activated.
In the event of a fault, apply the interpretation of DF046 Battery voltage.
"ABSENT"If the + after ignition is not activated, ET001 is "Absent".
In the event of a fault, apply the interpretation of DF046 Battery voltage.

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
