Impossible to select N
Impossible to start engine with gear engaged, even with brake
pedal depressed
NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
Use the Wiring Diagrams Technical Note for New TWINGO.
Check the + after ignition feeds and the earths of the sequential gearbox computer.
Check the condition of the gear lever contacts and that it is operating correctly (consult the interpretation of
statuses ET043 "Lever contact No. 0", ET044 "Lever contact No. 1", ET045 "Lever contact No. 2" and
ET046 Lever contact No. 3").
Repair if necessary.
Check for the presence and condition of the brake light switch supply fuse on the passenger compartment fuse
board.
Repair if necessary.
Check that the brake light switch connector is correctly connected, check the condition of the connections as well
as those of the computer.
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
Check that the brake light switch on the pedal is correctly fitted and adjusted.
Check for continuity, with the pedal depressed, between connections AP10 (track 2) and 65A of
component 160.
Replace the switch if necessary (see MR 411 Mechanical, 83D Cruise control, Brake light switch: Removal -
Refitting).
Check there is no continuity with the pedal released, between connections AP10 (track 2) and 65A of
component 160.
Replace the switch if necessary (see MR 411 Mechanical, 83D Cruise control, Brake light switch: Removal -
Refitting).
If the fault is still present, check the continuity of the following connection:
●Connection code 65A between components 160 and 119.
Also ensure the insulation to earth.
AFTER REPAIRClear the computer fault memory. Switch off the ignition and wait 20 seconds.
Carry out a road test followed by another check with the diagnostic tool.

NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
Check the + after ignition feeds and the earths of the sequential gearbox computer.
Check that the gear lever is not jammed or damaged or even broken. Replace the lever if necessary (see MR 411
Mechanical, 21B, Sequential gearbox, Sequential gearbox selector lever: Removal - Refitting).
Apply the fault finding procedure for ET043 "Lever switch No. 0", ET044 "Lever switch No. 1", ET045 "Lever
switch No. 2" and ET046 Lever switch No. 3".
If the fault is still present, run a multiplex network test using the diagnostic tool (see 88B, Multiplex).
AFTER REPAIRClear the computer fault memory. Switch off the ignition and wait 20 seconds.
Carry out a road test followed by another check with the diagnostic tool.

ALP 6No creeping
Brake lights permanently lit
Forward or reverse gear can be selected without depressing the
brake pedal
NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
In a case where there is no creeping, if the customer has heard the buzzer whilst
driving, it is normal for creeping to be prohibited (clutch overheating). Leave the clutch
to cool down and then check if there is any creep. Apply the following procedure if the
fault persists.
Use the Wiring Diagrams Technical Note for New TWINGO.
Check for the presence, condition and correct positioning of the brake light fuse in the passenger
compartment fuse box.
Check the connection and condition of the connectors of components 160, 156 and 119.
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
Check the fitting and adjustment of component 160 on the pedals.
Pedal depressed:
Check the continuity between connections AP10 (track 2) and 65A of component 160.
Check the insulation between connections AP10 (track 4) and 5A of component 160.
If the checks are incorrect, replace the switch (see MR 411 Mechanical systems, 83D Cruise control, Brake
light switch: Removal - Refitting).
Pedal released:
Check the insulation between connections AP10 (track 2) and 65A of component 160.
Check the continuity between connections AP10 (track 4) and 5A of component 160.
If the checks are incorrect, replace the switch (see MR 411 Mechanical systems, 83D Cruise control, Brake
light switch: Removal - Refitting).
Check the continuity and insulation from earth of the following connection:
●Connection code 65A,
between components 160 and 119.
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.
AFTER REPAIRClear the computer fault memory. Switch off the ignition and wait 20 seconds.

ALP 11 Display and warning buzzer operation erratically
NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
–The buzzer is active:
–when the front doors are opened,
–if the clutch overheats while the vehicle is being driven,
–if the sequential gearbox programming has not been carried out.
–The depress brake pedal symbol is active:
–when the engine is stopped by a gear lever request or if the lever is accidentally shifted to the neutral
position while the vehicle is being driven.
Carry out a road test to recreate the customer complaint.
Carry out the following programming:
–VP008 “Program selection/engagement ranges”.
–Program the biting point using command:
RZ003 Clutch biting point programming
Exit fault finding mode and switch off the ignition.
Wait 1 minute and then re-establish dialogue with the computer.
Shift the gear lever to rest position (Stb).
Start the engine.
Wait 10 seconds without changing gear (for programming the clutch biting point).
Check that programming has been successfully completed by referring to the following status:
ET062 “Biting point programming” displays “Done”.
Repeat the procedure if unsuccessful.
AFTER REPAIRClear the computer fault memory. Switch off the ignition and wait 20 seconds.
Carry out a road test followed by another check with the diagnostic tool.

NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
If a gear was engaged when there is a request to start the engine check the oil level in the sequential gearbox
circuit.
Check the operation of the brake pedal switch as well as the condition of the gear lever switches (consult the
interpretation of statuses: ET043 “Lever switch no. 0”, ET044 “Lever switch no. 1”, ET045 “Lever switch
no. 2” and ET046 “Lever switch no. 3”).
Ensure that the cylinder and the clutch fork are operating correctly (damage, seizing, part breakage, etc.).
AFTER REPAIRClear the computer fault memory. Switch off the ignition and wait 20 seconds.
Carry out a road test followed by another check with the diagnostic tool.
