If the checks are incorrect, replace the switch (see MR 411 Mechanical, 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 insulation between connections AP10 (track 4) and 5A of component 160.
If the checks are incorrect, replace the switch (see MR 411 Mechanical, 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, check the connection and condition of intermediate connector R67 located near the
engine fuse and relay box.
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 fault finding of the following computers:
●The UCH (see 87B, Passenger compartment connection unit).
●The injection computer (see 17B, Petrol injection).
●The ABS computer (see 38C, Anti-lock braking system).
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.

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.
