NOTESSpecial note:
Fault warning light comes on.
Starting is not permitted until the driver has depressed the brake pedal (enabling
neutral to be engaged).
Use the Wiring Diagrams Technical Note for New TWINGO.
Check the connection and condition of the connectors of components 1055 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 continuity and insulation to earth and to + 12 V on the following connections:
●Connection code 5HN,
●Connection code 5HX,
●Connection code 5FA,
between components 1055 and 119.
If the connections are faulty, check the connection and condition of the intermediate connector R235 located on
the hydraulic unit.
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.
Remove the engagement position sensor and check the wear of the cylinder-potentiometer mechanical
connection.
(see MR 411 Mechanical, 21B, Sequential gearbox, Engagement position sensor).
Repair if necessary.
If the checks are correct, replace the engagement position sensor (see MR 411 Mechanical, 21B, Sequential
gearbox, Engagement sensor: Removal - refitting).
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.

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.

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.
