NOTESConditions for applying the fault finding procedure to a stored fault:
If the fault becomes present during a road test at over 21 mph (35 km/h).
Special notes:
– the cruise control/speed limiter function is switched off.
Use bornier Elé. 1681 for all operations on the engine management computer
connector.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
Check the condition of the clutch sensor connector (see Wiring Diagram Technical Note, Laguna II ph2, Vel
Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 675).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
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.
Display status ET405 Clutch pedal switch (can only be displayed for Manual Gearboxes) which is normally
INACTIVE when the pedal is not depressed.
Depress the clutch pedal and note whether this status becomes ACTIVE.
If the status becomes ACTIVE when the clutch pedal is in the rest position.
Clear the fault, switch off the ignition, wait for the end of the power-latch and wait for the diagnostic tool message
(maximum wait 8 min): Loss of dialogue with the computer: EDC16 CP33, check the tool connection and the
computer supply voltage and switch on the ignition again.
Carry out a road test and then take a fault reading.
If the fault is still present, contact the Techline.

Check the + 12 V after relay supply to the brake pedal switch on the following connections:
•SP13 of component 160,
•AP10 of component 160.
Disconnect the ABS/ESP (electronic stability program) computer and check the continuity and insulation
from + 12 V and from earth of the following connections:
•65A between components 1094 (or 118) and 160,
•65G between components 1094 and 160.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Remove the brake pedal switch and check that it is working correctly:
– in the rest position: infinite resistance between connections SP13 and 5A of component 160.
– depressed: continuity between connections SP13 and 5A of component 160.
Replace the switch if necessary.
If the fault is still present, run fault finding on the ABS/ESP (see 38C, Anti-lock braking system), then
