NOCheck that the "Automatic brake light" function is activated using status
ET030 Automatic brake light.
If the status ET030 "Automatic brake lights" is "PROHIBITED":
inhibit or authorise the automatic brake lights (depending on the country's legislation)
using command VP021 Automatic brake light inhibition or VP022 Automatic brake
light authorisation.
Check the condition and position of fuse F5 (15 A) in the passenger compartment
fuse box (see 81C, Fuse box).
Connector of components 1281, 1094 and intermediate union R107 disconnected,
Check the continuity of connection 4GJ between component 1281 and intermediate
union R107.
Check the continuity of connection 4GJ between intermediate union R107
and component 1094.
If the connections are faulty (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
With the connector of components 1281 and 1016 disconnected, check the continuity
and insulation of connection AP10 between components 1016 and 1281.
If the connection is faulty (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If all these checks are in order, replace component 1281.

1.DEF: Inconsistency
2.DEF: Permanent high signal
NOTESConditions for applying the fault finding procedure to stored faults:
Clear the stored fault, carry out a road test at a speed of > 36 mph (60 km/h) and test
the brakes using ABS.
Use the interpretation of the fault if it recurs.
Special notes:
The fault is detected if the computer does not detect a brake lights switch status change
for 4 acceleration/braking cycles and/or the contact is closed for over 6 minutes with
the vehicle speed above 24 mph (40 km/h).
Using the diagnostic tool, check on the status screen that ET017 Brake pedal recognises the correct pressed
and released positions of the brake pedal.
If the correct pedal position is not displayed, use the interpretation of ET017 Brake pedal.

NOTESSpecial notes:
Only carry out the checks if the PRESSED and RELEASED statuses are inconsistent
with the pedal position.
Use the Wiring Diagram Technical Note for New Twingo.
"Released" STATUS Brake pedal depressed.
If the brake lights are working:
With the connectors of components 1094, 160, intermediate union R107 and component 119 disconnected
(depending on equipment), check the continuity of connection 65A between components 160 and 1094.
If the connection is faulty (see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
If the brake lights are not working:
–Check the condition, fitting and the adjustment of component 160 as well as the conformity of the bulbs.
–Remove (see MR 411, Mechanical, 37A, Mechanical component control, Brake light switch: Removal -
Refitting) and test the operation of component 160:
Continuity between tracks Insulation between tracks
Switch engaged
(Brake pedal released)AP10 and 5A AP10 and 65A
Switch released
(Brake pedal depressed)AP10 and 65A AP10 and 5A
Replace component 160 if necessary.
Check the condition and position of fuse F5 (15A) (see 81C, Fuse box).
Check for +12 V after ignition feed on connection AP10 of component 1016 to the earth MAH.
With intermediate connector R107 and component 160, 1281 and 1081 disconnected (depending on equipment):
–Check the continuity and insulation of connection AP10 between component 1016 and intermediate
