Engage reverse gear.
Check for + 12 V on connection H66P of component 172 (left-hand drive) or 173 (right-hand drive).
If there is no + 12 V, check the insulation and continuity of connection H66P between components 155 and
172 (left-hand drive) or 173 (right-hand drive).
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 fault finding on the UCH (see 87B, Passenger Compartment Connection
Unit).
If the vehicle is fitted with the parking distance control system, perform fault finding on the parking distance control
computer (see 87F, Parking distance control).
If the supply and earth of the reversing light are correct, replace the reversing light.
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.
Carry out a road test followed by another check with the diagnostic tool.

ALP 8Vehicle does not move forward with gear engaged and engine
running
NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
Apply the fault finding procedure associated with the multiplex network test (see 88B, Multiplexing).
Check the mechanical condition of the clutch (no grease or leaks on the flywheel, clutch driven plate not cracked
or disintegrated, no broken parts, etc.).
Check the condition of the driveshaft (broken joint, internal gearbox mechanical fault etc.).
Repair or replace the faulty components.
If the engine speed remains at idle speed, check the positioning of the accelerator pedal sensor.
Run fault finding on the injection system (see 17B, Petrol Injection).
If the fault is still present, contact Techline.
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 9 Inadequate reaction to full load request
NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
Carry out a road test and check for a hard point on the accelerator pedal under full load and on consecutive
downshifting.
If the hard point is noticeable on the pedal but not when downshifting, perform another road test with the selector
in automatic mode.
If downshifting is still not active, use the diagnostic tool to check that status ET030 Accelerator pedal position
varies depending on the pedal position.
Check the operation of the pedals (pedal travel fault or pedal potentiometer damaged).
If the fault is still present, check the injection system (see 17B, petrol injection).
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 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.

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.
