For CLIO III or MODUS:
Reconnect the Protection and Switching Unit connector and reconnect the battery.
If, with the ignition on, there is still no + 12 V on the fuel vapour absorber
canister bleed solenoid valve connector, there is a fault in the Protection and Switching Unit.
Carry out fault finding on the UPC (see 87G, Engine compartment connection unit).
If the fault is still present, contact the Techline.
For NEW TWINGO or E33:
Reconnect the injection locking relay connector and reconnect the battery.
With the ignition on, if there is still not + 12V on the connector for the fuel vapour absorber bleed solenoid, there is
a fault in the engine fuse and relay box.
Carry out fault finding on the engine fuse and relay box, by checking the continuity of the following connection:
●BP17 between components 120 and 397, 238 and 397.
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.
If the fault is still present, check the battery and run fault finding on the charging circuit (see Technical Note 6014A,
Checking the charging circuit).
Disconnect the battery.
Check the condition of the engine management computer connector (see Wiring Diagrams Technical Note for
NEW TWINGO, E33, CLIO III, or MODUS, 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.
Use the universal bornier to check the insulation and continuity of the following connection:
●3BB between components 120 and 371.
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 earth on connection 3BB of the fuel vapour absorber bleed solenoid valve when running command
AC017 Canister bleed solenoid valve.
Replace the fuel vapour absorber bleed solenoid valve.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
Repeat the conformity check from the start.

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.

CHECK
ON
VEHICLE
Check the electrical voltage of the battery.
Check the cleanliness and condition of the battery terminals.
Check the condition of the battery earth cable and ensure that there is a good
electrical connection with the bodywork.
Check the condition of the engine management computer connector
(component code 120).
If the connector is faulty and there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for repair), repair the connector,
otherwise replace the wiring.
Check the injection computer earth terminal for cleanliness and make sure it is
correctly connected to the bodywork.
Check the 30 A supply fuse of the injection locking relay, and the condition and
cleanliness of the contacts.
Check the 40 A supply fuse of the Protection and Switching Unit and the condition
and cleanliness of the contacts.
Check the injection computer after ignition feed 20 A fuse, and the condition and
cleanliness of the contacts.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
Repeat the conformity check from the start.
