1.DEF: EOBD
NOTESPriorities when dealing with a number of faults:
Firstly, deal with the following faults:
–DF046 Battery voltage,
–DF084 Actuator relay control circuit,
–DF085 Fuel pump relay control circuit,
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the starter has been in operation for 10 seconds or
after the engine has been running for 10 seconds.
Special notes:
If a fault is present, injectors 2 and 3 are switched off after 60 seconds at
600 rpm or 6 seconds at 6000 rpm, until the ignition is switched off.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Disconnect the quadruple ignition coil module connector and check the cleanliness and condition of its connections
(component code 108) and 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.

Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the engine starts.

Check the appearance and condition of the catalytic converter. Check there are no air leaks, thermal shock,
misfiring, coolant or oil consumption.
Run command SC006 Running OBD Test: catalytic converter. Before carrying out this test, repair all the
electrical faults and clear the fault memory. Check that fault DF436 Misfiring detection is not present and program
the engine flywheel target ET089 Flywheel target programming.
Carry out this test when the engine is warm, which reduces the time it takes for the catalytic converter to heat up.
At the end of this test, four different results are possible:
–Status 1: Fault finding not carried out/impossible to obtain the necessary conditions.
–Status 2: Component in an average condition.
–Status 3: Component in good condition.
–Status 4: Component in poor condition.
When fault finding is completed and the result read, stop the engine and start it again to establish normal operating
conditions.
If the result is status 1: check that there are no faults, and check the engine flywheel target programming using
ET089 Programming engine flywheel target.
If the result is status 2 or 4: replace the catalytic converter.
If the result is status 3: the catalytic converter is in good condition.
If the fault is still present, contact the Techline.

Clear the stored faults. Do not clear the programming.
To check that the system has been properly repaired:
–there must be no further electrical faults,
–programming has been carried out,
the engine must be warm (minimum 75˚C), and idling, with all electrical consumers
running for 15 minutes.

WARNING:
Never drive the vehicle without having confirmed that no faults involving the throttle valve are present.
NOTESPriorities when dealing with a number of faults:
If faults DF095 Throttle potentiometer circuit gang 1 and DF096 Throttle
potentiometer circuit gang 2 are present, deal with these first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared as present with the ignition on or the engine running, or during
command AC027 Motorised throttle.
Special notes:
In the event of faults, the level 1 warning light comes on, the injection goes into defect
mode 1 and 2, causing a limitation of vehicle and engine speed. The ESP and the cruise
control - speed limiter are deactivated.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the connector of the engine throttle valve (component code 120) and of the throttle valve
(component code 1076).
If the connector or 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.

NOTESConditions for applying the fault finding procedure to stored faults
The fault is declared present with the engine running.
Special note:
Defect mode 4: speed limited to less than 66 mph (110 km/h) in 5th and 6
th and the
accelerator pedal feels spongy.
Defect mode 5: the ESP and Cruise control - Speed limiter are deactivated.
Defect mode 6: the wastegate is not controlled and opens freely.
The engine runs without turbocharging, like a naturally aspirated engine.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III, or
MODUS.
Check the connection of the turbocharging ducts.
Check the condition of the connector of the turbocharger pressure sensor (component code 1071), of the
wastegate solenoid valve (component code 436), and of the engine management computer (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 connections:
●3AHN between components 436 and 120,
●3AT between components 436 and 120,
●3LN between components 1071 and 120,
●3LP between components 1071 and 120,
●3LQ between components 1071 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical

STOREDACCELERATOR PEDAL POSITION SIGNAL
1.DEF: Signal incoherent
NOTESConditions for applying the fault finding procedure to stored faults:
If the customer complains of intermittent faults typical of defect mode type 3
(no accelerator pedal, cruise control or speed limiter), and that the ESP indicator
light comes on but the injection system displays no present faults, apply this fault
finding procedure.
Special notes:
This fault finding procedure enables an accelerator pedal mechanical seizure type fault
to be displayed whilst the pedal is depressed (when the driver's foot is lifted, the pedal
position remains the same). In this case, the driver will brake.
This program enables an inconsistency in the driver's behaviour, such as the brake
pedal and accelerator being depressed simultaneously to be detected (but enables
heel/toe points and left foot braking to be performed without displaying a fault).
There are two possible cases:
1. The fault finding procedure detects constant acceleration then braking with the
acceleration still maintained => change to reversible type 3 defect mode (see
System operation) which no longer recognises the accelerator pedal => warning
light does not come on, fault is not stored. If the accelerator pedal changes position
before the end of a time delay (approximately 31 seconds), it exits defect mode
and returns to normal mode.
2. If the accelerator pedal does not change position for the entire time delay
(approximately 31 seconds), it goes irreversibly into defect mode (requires the
ignition to be switched off to exit it). The warning light comes on and the fault is
stored. This fault finding procedure has no relation with the throttle position.
An accelerator fault (locking, for example) is needed to show the stored fault.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.

NOTESPriorities when dealing with a number of faults:
Deal first with fault DF084 Actuator relay control circuit or DF046 Battery voltage
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present when the engine is running.
Special note:
Controlled coolant thermostat:
–For CO and CC.1:
Thermostat not controlled; temperature regulation performed at 110˚C.
–For CC 0:
Thermostat continuously controlled; temperature regulation performed at 90˚C.
Use Wiring Diagram Technical Note for CLIO III or MODUS.
Check the condition of the controlled coolant thermostat connector (see Technical Note Wiring Diagram, CLIO III
or MODUS, component code 1458).
Check the condition of the engine management computer connector (see Technical Note Wiring Diagram,
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.
If the fault is still present, check (with the ignition on) for + 12 V on connection 3FB of the controlled coolant
thermostat.
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.
Use the "universal bornier" to check the insulation and continuity of the following connection:
●3VL between components 1458 and 120.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
