ACTUATORS (Continued)
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.
AC081 "Discharge pressure accumulator"
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,
–replacing or reprogramming the computer,
–replacing the engagement position sensor and the selecting position sensor,
–replacing the engagement, selection or clutch solenoid valves.
–replacing the reservoir, accumulator or pump only.

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.

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.
