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
connector R107.
–Check the continuity and insulation of connection AP10 between component 160 and intermediate
connector R107.

Replace component 160 if necessary.
Connectors of components 645, 172, 173, 639 and 1094, intermediate connectors R107 and R15 and connector
of component 119 (if present on the vehicle) disconnected from connection 65A:
Check the insulation of connection 65A between component 160 and intermediate connector R107.
Check the insulation of connection 65A between component 172 and intermediate connector R107.
Check the insulation of connection 65A between component 173 and intermediate connector R107.
Check the insulation of connection 65A between intermediate connectors R107 and R15.
Check the insulation of connection 65A between component 639 and intermediate connector R15.
Check the insulation of connection 65A between component 645 and intermediate connector R107.
If the connection is faulty (see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
If these checks do not reveal any faults:
Perform a complete check of component 645 using the diagnostic tool.
Perform a visual inspection of components 172, 173, 639 present on connections 65A and AP10 (short circuit to
earth).
Replace the component(s) if necessary:
See MR 411 Mechanical, Rear lighting, Rear wing lights, Removal - Refitting for components 172 and 173.
See MR 411 Mechanical, Rear lighting, High level brake light, Removal - Refitting for component 639.
