Use the universal bornier to check the insulation and continuity of the following connection:
●3GG between components 242 and 120.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for an earth on connection 3GJ of the downstream oxygen sensor whilst running command AC118
Downstream O2 sensor heating.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Measure the heating resistance of the downstream oxygen sensor:
If the resistance of the downstream oxygen sensor is not between:
●8 Ω < X < 10 Ω at 20˚C, replace the sensor.
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.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is considered present when the engine is running.
Special notes:
If the fault is detected, the fast idle speed request and power consumption are
cancelled.
Use Wiring Diagram Technical Note for CLIO III or MODUS.
Run a multiplex network test (see 88B, Multiplex).
If the fault is still present, run fault finding on the UCH (see 87B, Passenger compartment connection unit).

CC.0: Short circuit to earth
CC.1: Short circuit to + 12 V
1.DEF: EOBD
NOTESConditions for applying the fault finding procedure to stored faults
The fault is declared present with the engine running.
Special note:
CO or CC.1: High speed fan assembly not activated, risk of engine overheating (the
coolant warning light should warn of overheating), risk of loss of air conditioning.
CC.0: High-speed fan assembly permanently activated.
The customer complains of slight overconsumption and noise in CC.0.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the high-speed fan assembly relay connector (component code 234) and 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 AC153 High speed fan assembly.
If the command does not work, with the ignition on, check for + 12 V on connection 3FB of the high-speed fan
assembly relay and the earthing of connection 3JP on the injection computer connector.
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.
Use the universal bornier to check the insulation and continuity of the following connections:
●3FB between components 234 and 238,
●3JP between components 234 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.

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.

"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).
