NOTESPriorities when dealing with a number of faults:
If fault DF062 Multiplex line fault is present or stored, deal with it first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the computer fault memory has been cleared, the
ignition has been switched off and on again and the engine has been started.
Use the Wiring Diagrams Technical Note for New TWINGO.
Run a multiplex network test (see 88B, Multiplex).
Run fault finding on the injection system (see 17B, Petrol injection).
Check for the presence, condition and correct positioning of the 15A fuse for the brake lights in the passenger
compartment fuse box.
Check that the indicator light switches off quickly as soon as the brake pedal moves.
Check the connection and condition of the connectors of components 120 and 160.
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 adjustment of the brake light switch on the pedals.
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 systems, 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 systems, 83D Cruise control, Brake light switch:
Removal - Refitting).
Ensure the insulation to + 12 V, to earth and the continuity of the following connections:
●Connection code 3MT,
●Connection code 3MS,
between components 120 and 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.
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 LIGHT SWITCH (OPENING)
STOP LIGHT SWITCH (CLOSURE)
STATUS
DEFINITIONThese statuses indicate the position of the brake pedal.
NOTESUse the Wiring Diagrams Technical Note for New TWINGO.
Engine stopped, ignition on
–Brake pedal released: ET003: "Closed" and ET004: "Open".
–Brake pedal depressed: ET003: "Open" and ET004: ''Closed".
If the statuses do not correspond with the position of the brake pedal, perform the following fault finding
procedure.
Electrical check of the sensor
Check the condition of the 15 A fuse of the brake light switch located on component 1016.
Check the brake light switch is correctly positioned on the brake pedal.
Check the condition and correct connection of component 160.
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 the + after ignition feed on both connections AP10 of component 160.
If there is no + after ignition feed, check the continuity and insulation to earth of the two connections AP10
between components 160 and 1016.
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.
Pedal released:
Check the continuity between connections AP10 (track 4) and 5A of component 160.
Check the insulation between connections AP10 (track 2) and 65A of component 160.
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 one of these checks is incorrect, replace the brake light switch (see MR 411 Mechanical, 83D Cruise control,
Brake light switch: Removal - Refitting).
AFTER REPAIRCarry out another fault finding check on the system.
Deal with any other faults.
Clear the stored faults.

ET012
GEAR LEVER POSITION
STATUS
DEFINITIONThis status ET012 indicates one of the six positions of the gear lever: UP, DW, N, R,
STB or A.
NOTESNone
Engine stopped, ignition on
Check the specification of status ET012 for each position of the gear lever:
●movement towards the front of the vehicle: "UP".
●movement towards the rear of the vehicle: "DW".
●Movement to the right: "N".
●Movement to the left: "A".
●Brake pedal depressed, movement to the right followed by a movement to the rear: "R".
●Lever in rest position: "STB".
If status ET012 is not consistent with the position of the gear lever each time it is moved, refer to the interpretation
of fault DF067 "Lever position switch circuit".
AFTER REPAIRCarry out another fault finding check on the system.
Deal with any other faults.
Clear the stored faults.

GEAR ENGAGED
STATUS
DEFINITIONThis status ET013 indicates the gear engaged and corresponds to the gear displayed
on the instrument panel:
●1: 1st
●
2: 2nd
●
3: 3rd
●
4: 4th
●
5: 5th
●
N: Neutral
●R: Reverse
NOTESNone
Engine stopped, ignition on
Check the specification of status ET013 each time the gear lever is moved:
●Gears 1st to 5th: push the lever forwards for the next gear up and backwards for the next gear down and
check how status ET013 changes each time the gear lever moves.
●Position N (neutral): when status ET013 is "1", push the lever to the right and check that status ET013 is
"N".
●Gear R (reverse): check status ET013 changes to "R" after depressing the brake pedal, pushing the lever to
the right and then to the rear.
If status ET013 is not correct, refer to the interpretation of faults DF069 "Selection position circuit" and DF070
"Engaging position sensor circuit".
AFTER REPAIRCarry out another fault finding check on the system.
Deal with any other faults.
Clear the stored faults.

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).
