SETTINGS
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.
VP008: "Selection/engagement zones programming"
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.
VP009: "Enter last After-Sales operation date"
Use this command for each workshop operation on the sequential gearbox.
Select command VP009 on the diagnostic tool.
Enter the operation date with the tool keyboard.
VP013: "Enter new clutch fitting date"
This command should be used when the clutch is replaced.
Select command VP013 on the diagnostic tool.
Enter the operation date with the tool keyboard.
VP014: "Enter clutch initial closed position"
This command enables the value of the initial closed position of the clutch to be re-entered into a new or
reprogrammed computer in order to keep a consistent record of the clutch wear,.
Use this command each time the computer is replaced or reprogrammed. Note:
When replacing or reprogramming a computer, use command AC007 Hydraulic unit pump rehabilitation
before carrying out parameter VP008 Program selection/engagement ranges.

1.DEF: Internal electronic fault
NOTESSpecial note:
–fault warning light comes on.
Use the Wiring Diagrams Technical Note for New TWINGO.
Check the condition and positioning of the following fuses:
●Fuse F1 (30A) located in the engine fuse and relay box.
●Fuses F16 (20A) and F4 (7.5A) located in the passenger compartment fuse box.
Check the connection and condition of the 52-track connector of component 119.
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 for + before ignition on connection BP39 and for + after ignition feed on connection AP4 on the
connector of component 119.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the wiring, otherwise replace it.
Check the insulation, continuity and the absence of interference resistance on the following connections:
●Connection code N between component 119 and the chassis earth MC - 12A.
●Connection code N between component 119 and the chassis earth MC - 12B.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the wiring, otherwise replace it.
Clear the computer fault memory and exit fault finding.
Switch off the ignition.
Switch on the ignition again and carry out a new check using the diagnostic tool.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
