Fault finding - System operation21B
Operation in MANUAL mode (continued):
–when driving, the selection of “N” is only accepted by the sequential gearbox computer if the driver's foot
is on the brake pedal,
–when driving, selection of reverse gear is prohibited,
–when the vehicle is slowing down and the speed is approaching 0 mph, the sequential gearbox computer
automatically selects 1
st gear.
In manual mode, the driver decides when to change gears by:
–moving the gear lever towards “+” which enables a higher gear to be selected,
–moving the gear lever towards “-” which enables a lower gear to be selected,
–moving the gear lever to “N” which enables neutral to be selected,
–moving the gear lever to “R” which enables reverse gear to be selected.
Operation in AUTO mode:
Automatic mode frees the driver from having to worry about changing gear: instead, the sequential gearbox
computer determines when best to change gear in relation to the different vehicle parameters (speed, acceleration,
position of accelerator pedal etc.,).
The main characteristics of automatic mode are as follows:
–AUTO mode only functions when the engine is running.
–AUTO mode is preselected when the engine is started.
The AUTO mode entry conditions are as follows:
–Moving the gear lever to the left (towards A/M) when manual mode is selected, when a forward gear is
engaged and AUTO mode was selected.
–Engine started.
To exit AUTO mode when driving and under normal operating conditions (no faults), the following exit conditions
must be met:
–Movement of the gear lever to the left (deselecting automatic mode using the lever).
–Movement of gear lever towards “+” (except when changing from R to 1 or N to “X”).
–Movement of the gear lever towards “-” (except when changing from N to “X” or when reverse gear is
engaged).
Buzzer operation:
The buzzer operates in the following cases:
–Safety risk: the buzzer sounds when one of the front doors is opened, if the following conditions are met:
–the engine is running,
–a gear is engaged,
–the driver is not applying the brakes.
–The buzzer will cut out if one of the following conditions is confirmed:
–the engine is not running,
–the driver applies the brakes,
–the driver closes the door(s).
–Driver warning when push-starting vehicle:
–The buzzer will sound to inform the driver that moving the lever to select a gear will enable the engine to
start. The buzzer will sound when the vehicle has reached the speed that will allow the engine to start.
–When the computer detects that the clutch is overheating.

STOREDCLUTCH TEMPERATURE
1.DEF : Clutch overheating
NOTESPriorities when dealing with a number of faults:
Deal with other faults declared present first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the clutch is used under severe conditions
(prolonged holding on a hill).
Special note:
–Instrument panel displays: “Sequential gearbox overheating”
–Fault warning light comes on.
–An engine speed wire fault or incorrect multiplex line value (speed equals 0) may
increase the occurrence of this fault.
Clear the stored fault and check that the clutch is not slipping by performing a road test, pulling away with a low
load then up or down an incline.
If the clutch slips, proceed in the following way:
–Pull away several times with low load and check parameter PR096 Clutch progressivity.
–If the fault is still present, replace the clutch.
AFTER REPAIRDeal with any faults detected by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

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.
