COMPUTER SUPPLY VOLTAGE
PARAMETER
DEFINITIONThis parameter indicates the sequential gearbox computer supply voltage value
expressed in V.
NOTESUse the Wiring Diagrams Technical Note for New TWINGO.
Engine stopped, ignition on
PR008 ≈ 12 V
The computer supply voltage value must be close to the battery voltage.
Electrical check of the component
Check that the sequential gearbox supply fuse is correctly positioned and in good condition in the engine
compartment connection unit.
Check the engine earths on the vehicle are in good condition.
Repair if necessary.
Measure the battery voltage and check the charge circuit (see Technical Note 6014A, Charge circuit check).
Check the connection and condition of the connections of component 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 continuity and insulation of the following connections:
●Connection code BP39,
●Connection code AP4,
between components 1016 and 119.
●Connection code N (2 connections) between earths MC-12A and MC-12B and 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.

Diagnostic - Fault finding chart
ALP 1 No dialogue with the sequential gearbox computer
NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic
tool.
Use the Wiring Diagrams Technical Note for New TWINGO.
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty. If
the tool is not causing the fault and dialogue cannot be established with any other computer on the same vehicle,
it may be that a faulty computer is disrupting the CAN diagnostic line.
Use a process of successive disconnections to locate this computer.
Check the voltage of the battery and carry out the operations necessary to obtain a voltage which is to
specification (9.5 V < battery voltage < 17.5 V).
Check the presence of and condition of the Sequential Gearbox fuses on the passenger compartment fuse box
(7.5 A and 20 A).
Check that the computer connector is properly connected and check the condition of its connections.
Check the sequential gearbox earths (good condition, not corroded, tightness of the earth bolt above the
hydraulic unit).
Check that the supply to the computer is correct:
–Earth on the N connections of the 52-track connector.
–+ AVC on connection BP39 of the 52-track connector.
–+ after ignition feed on connection AP4 of the 52-track connector.
Check that the power supply to the diagnostic socket is correct:
–+ AVC on connection BP19.
–Earth on connections MAM and NAM.
If dialogue has still not been established after these checks, contact the 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 2Cannot select a forward or reverse gear when stationary
Impossible to select N
Impossible to start engine with gear engaged, even with brake
pedal depressed
NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
Use the Wiring Diagrams Technical Note for New TWINGO.
Check the + after ignition feeds and the earths of the sequential gearbox computer.
Check the condition of the gear lever contacts and that it is operating correctly (consult the interpretation of
statuses ET043 "Lever contact No. 0", ET044 "Lever contact No. 1", ET045 "Lever contact No. 2" and
ET046 Lever contact No. 3").
Repair if necessary.
Check for the presence and condition of the brake light switch supply fuse on the passenger compartment fuse
board.
Repair if necessary.
Check that the brake light switch connector is correctly connected, check the condition of the connections as well
as those of the computer.
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 that the brake light switch on the pedal is correctly fitted and adjusted.
Check for continuity, with the pedal depressed, between connections AP10 (track 2) and 65A of
component 160.
Replace the switch if necessary (see MR 411 Mechanical, 83D Cruise control, Brake light switch: Removal -
Refitting).
Check there is no continuity with the pedal released, between connections AP10 (track 2) and 65A of
component 160.
Replace the switch if necessary (see MR 411 Mechanical, 83D Cruise control, Brake light switch: Removal -
Refitting).
If the fault is still present, check the continuity of the following connection:
●Connection code 65A between components 160 and 119.
Also ensure the insulation to earth.
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 5 No reversing lights
NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
Use the Wiring Diagrams Technical Note for New TWINGO.
Check the condition of the bulbs for the reversing lights.
Replace if not correct.
Check the conformity of the supply fuse of the reversing light switch (15 A) located on the passenger
compartment fuse box.
Replace the fuse if not correct.
If, following replacement of the fuse and switching on the ignition, the fuse is not correct, check the insulation to
earth of connection AP3 between components 1016 and 155.
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.
Replace the faulty fuse.
If the fuse is correct, check the presence of + 12 V on connection AP3 of component 155.
If there is no + 12 V, check the continuity of connection AP3 between components 1016 and 155.
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.
Check the conformity of the reversing lights switch:
●Switch in rest position: insulation between connections AP3 and H66P of component 155.
●Switch depressed: continuity between connections AP3 and H66P of component 155.
Replace the reversing lights switch if not correct.
Check for the earth of the reversing light on the following connection(s):
●Left-hand drive: connection MF of component 172.
●Right-hand drive: connection MG of component 173.
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.

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.

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.
