STOREDBRAKE SWITCH 2 CIRCUIT
1.DEF: No signal
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is present after the ignition has been switched on and the brake pedal has
been depressed.
Special notes:
The fault appears after a fault on one of the two brake switch contacts.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check:
–the consistency of statuses ET704 Brake switch no. 1 and ET705 Brake switch no. 2 becoming ACTIVE -
INACTIVE when the brake pedal is depressed,
–the condition and cleanliness of the brake lights switch, component code 160.
Disconnect the battery and the injection computer, check the condition and cleanliness of the injection computer
connections, 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 insulation and continuity of the following connection:
●5A between components 120 and 160.
If the connection is 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 a fault finding procedure on the Anti-lock Braking System (see 38C, Anti-lock
Braking System).
If the fault is still present, contact the Techline.
SIM32_V44_DF128/SIM32_V4C_DF128/SIM32_V54_DF128
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.

STOREDCLUTCH SWITCH CIRCUIT
1.DEF: Open circuit or short circuit
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present at a driving speed of over 36 mph (60 km/h) and after
more than twenty gear changes without the clutch pedal being detected as having been
depressed.
Special notes:
In the event of open circuit or short circuit to + 12 V: the clutch pedal is seen by the
system as being permanently depressed. This makes it impossible to select a cruising
speed in cruise control mode. The speed limiter remains operational in defect mode
(imprecise speed limiting). Engine speed surges when changing gear.
In the event of a short circuit to earth: the clutch pedal is still viewed as not being
depressed by the system, this causes bursts of engine speed when changing gear.
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 condition of the clutch pedal switch connector and its connections (component code 675) and 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 for an earth on connection M of the clutch pedal switch connector, component code 675.
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.

STOREDFLYWHEEL SIGNAL SENSOR CIRCUIT
1. DEF: Abnormal voltage
2.DEF: Tooth lost
3.DEF: EOBD
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is considered present when the engine is running.
Special notes:
In the event of flywheel signal loss, the injection and ignition are cut off: the vehicle stalls
and cannot be restarted.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the mounting and positioning of the flywheel signal sensor.
Repair if necessary.
Manipulate the wiring harness between the injection computer and the flywheel signal sensor in order to produce
a change in fault status (from present to stored).
Look for possible damage to the wiring harness.
Check the condition of the connector of the flywheel signal sensor (component code 149) 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:
●3BL between components 120 and 149,
●3BG between components 120 and 149.
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.

Measure the resistance of the flywheel signal sensor between connections 3BL and 3BG:
If the resistance of the flywheel signal sensor is not between:
200
Ω < X < 270 Ω at 23 ˚C, replace the sensor.
Disconnect the computer, use the universal bornier to check the signal from the flywheel signal sensor.
If it is fitted, use the Clip oscilloscope and make sure the square pulse signal of the sensor is not faulty (interference,
tooth missing, etc.).
If there is interference in the signal, check the air gap of the TDC 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.

NOTESPriorities when dealing with a number of faults:
Deal first with fault DF012 Sensor feed voltage no. 2 if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the accelerator pedal is depressed several times.
Special notes:
The level 1 fault warning light is lit, the throttle valve goes into defect mode 4, causing
a maximum speed limitation of 66 mph (110 km/h) and a loss of power when
accelerating (impression of having a "soft" pedal).
CO.0: The vehicle has a tendency to decelerate.
CC.1: The vehicle has a tendency to accelerate.
2.DEF: The throttle valve goes into defect mode 3, causing a driver's request loss
(no response from the accelerator pedal).
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check that the pedal mechanism has not seized.
Repair if necessary.
Check the condition of the pedal potentiometer connector (component code 921) 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.
