Fault finding - System operation21B
Description of gear lever positions (continued):
–"+": moving the gear lever towards this position enables the driver to shift up,
–“-”: moving the gear lever towards this position will enable the driver to shift down.
Description of the display:
This display is specifically for the sequential gearbox. It displays 4 types of information for the driver:
–displays the gear selected: 1, 2, 3, 4, 5, N or R,
–the pictogram displaying AUTO mode: this pictogram lights up when AUTO mode is selected,
–the “depress brake pedal” symbol: this symbol lights up when a driver action requires the brake pedal to be
depressed if the driver is not depressing the brake pedal. This symbol only lights up when there is an error (driver
actions without depressing the brake pedal = symbol lighting up),
–the sequential gearbox fault warning light: this lights up when the sequential gearbox computer detects a fault on
the sequential gearbox system.
General information about the operation:
Operation in MANUAL mode:
Manual mode allows the driver to select gears by moving the gear lever. However, in manual mode, the driver is not
completely free to do what he/she likes. This is why this mode is also called semiautomatic mode because the driver
is still assisted by the sequential gearbox computer in the following instances:
–when driving, shifting the lever towards the “+” position may result in underspeed. As a result, the sequential
gearbox computer forbids the driver's request,
–when driving, shifting the lever towards the “-” position may result in engine overspeed. As a result, the sequential
gearbox computer forbids the driver's request,
–when driving, as the overspeed threshold is approached, the computer automatically selects a higher gear,
–when driving, as the underspeed threshold is approached, the computer automatically selects a lower gear,
–when driving, if the vehicle speed reduces too quickly (brakes applied), the sequential gearbox computer can
order a downshift. Reminder:
Creep is only possible in first or reverse gears; it makes parking manoeuvres easier: if the brake pedal or
the handbrake is released, the vehicle moves forward by itself, without the driver having to accelerate.
Creeping is not possible in second gear.

HANDBRAKE
STATUS
DEFINITION"Engaged": the handbrake lever is raised.
"Released": the handbrake lever is in rest position.
NOTESUse the Wiring Diagrams Technical Note for New TWINGO.
Engine stopped, ignition on
Status ET028 indicates the position of the handbrake lever:
●"Engaged": the handbrake lever is raised.
●"Released": the handbrake lever is in rest position.
If status ET028 is incorrect, apply the procedure below.
Electrical check of the sensor
Run a multiplex network test (see 88B, multiplex).
Check the condition of the connections of component 156 and check that they are correctly connected.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Remove the handbrake switch.
Press the handbrake switch and check the insulation between connection 27A and earth.
If there is resistance, replace the handbrake switch.
Release the handbrake switch and check the continuity between the same connections.
If there is no continuity, replace the handbrake switch.
Check the condition of the connections of component 247 and check that they are correctly connected.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the continuity and the earth insulation on connection 27A between components 247 and 156.
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, perform a fault finding of the instrument panel (see 83A, Instrument panel).
AFTER REPAIRCarry out another fault finding check on the system.
Deal with any other faults.
Clear the stored faults.

SETTINGSAC014 "Clutch solenoid valve"
This command enables the clutch solenoid valves to be operated to perform a listening
check or to test their supply.
AC015 "Engagement solenoid valves"
This command enables the engagement solenoid valves to be operated to perform a
listening check or to test their supply.
AC016 "Selection solenoid valves"
This command enables the selection solenoid valves to be operated to perform a listening
check or to test their supply.
AC017 "Display"
This command enables the display integrity to be checked by searching through all the data
available relating to the sequential gearbox.
AC019 "Return gearbox to neutral"
This command returns the gearbox to neutral.
AC024 Sequential actuator control
This command enables all sequential gearbox switches to be operated in order to check that
they are working.
AC028 "Engage reverse gear"
This command enables reverse gear to be engaged.

This command enables pressure in the hydraulic circuit to be discharged. The handbrake
must be applied when using this command.
VP001 "Write VIN"
This command permits manual entry of the vehicle's VIN into the computer.
Use this command each time the computer is replaced or (re)programmed.
Note:
When replacing or reprogramming a computer, use command AC007 Hydraulic unit pump rehabilitation
before carrying out parameter VP008 Program selection/engagement ranges.
VP008 "Program selection/engagement ranges"
This command enables the gears to be programmed.
Use this command when:
–replacing the electrohydraulic unit, the clutch or the gearbox,
