running.
Special notes:
The cruise control/speed limiter is deactivated.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check that the pedal assembly is in good condition.
Check the cleanliness and condition of the dual-contact brake switch and its connections (component code 160)
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.
With the ignition on, check for + 12 V on connections 65A and 5A of the brake pedal switch, component code 160.

NOTESConditions for applying the fault finding procedure to stored faults
The fault is declared present when the ignition is switched on.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Run a multiplex network test (see 88B, Multiplex).
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.
For NEW TWINGO or E33:
Use the universal bornier to check the insulation and continuity of the following connections:
●133B between components 120 and 645,
●133C between components 120 and 645,
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, run fault finding on the UCH system (see 87B, Passenger compartment connection
unit).
For CLIO III or MODUS:
Use the universal bornier to check the insulation and continuity of the following connections:
●133B between components 120 and 1337,
●133C between components 120 and 1337.
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 UPC system (see 87G, Engine compartment connection
unit).
If the fault is still present, contact the Techline.

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,
