NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the brake pedal has been depressed several times.
Special notes:
1.DEF: If this fault is present, the cruise control - speed limiter is deactivated.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Carry out a consistency check on the brake contacts using ET704 Brake contact no. 1 and ET705 Brake
contact no. 2 when the pedal is depressed, the status should be "Depressed" and with no load on the pedal
it should be "Released".
–If there is inconsistency, check the condition of the brake light switch connector (component code 160) and the
engine management computer connector (component code 120).
–Check the condition of the connector. 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:
●5A between components 120 and 160.
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, test the multiplex network (see 88B, Multiplex).
If the fault is still present, run fault finding on the UCH system (see 87B, Passenger compartment connection
unit).
If the fault is still present, contact the Techline.

2.DEF: EOBD
NOTESConditions for applying the fault finding procedure to stored faults
The fault is considered present when the engine is running.
Special note:
1.DEF: The OBD warning light is lit.
Check the cleanliness and condition of the engine flywheel.
Check the mounting and condition of the engine speed sensor.
Check the condition and count the number of target teeth, if possible.
Repair or replace the engine flywheel if necessary.
If the flywheel has been replaced or removed, reinitialise the flywheel target, then program it.
Reinitialise programming:
Run command RZ005 Programming.
Programming the flywheel signal:
The engine must be warm. Decelerate a first time with injection cut-off (feet off the brake, accelerator, and clutch
pedals) between 3500 and 3000 rpm, in a gear above 3rd for at least 5 seconds for manual gearboxes.
Decelerate a second time with injection cut-off (feet off the brake, accelerator, and clutch pedals) between
2400 and 2000 rpm, in a gear above 3rd for at least 5 seconds for manual gearboxes.
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.

If the brake lights are working:
–Check the continuity and the absence of interference resistance of the
following connections:
●5A between components 160 and 120/645/119 (for NEW TWINGO or E33)
●65A between the components 160 and 120/645/119 (for CLIO III or MODUS).
If the connections are faulty and if there is a repair procedure (see Technical Note
6015A, Electrical wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace the wiring.
If the brake lights are not operational, check:
–the condition and fitting of the brake switch,
–the condition and conformity of the brake lights fuse.
–the conformity of the values in the following tables:
