BRAKE PEDAL
NOTESSpecial notes:
Only carry out the checks if the PRESSED and RELEASED statuses are inconsistent
with the pedal position.
Use the Technical Note wiring diagram for New Twingo.
STATUS
"RELEASED"
Brake pedal
depressed
If brake lights operate:
–Check the continuity of connection 65A between components 160 and 1094.
If the connector is faulty (see NT6015, Repairing electrical wiring, wiring: Precaution
for repairs), repair the connector, otherwise replace the wiring.
If the brake lights are not working:
–Check the condition, mounting and adjustment of the brake light switch and the
conformity of the bulbs.
–Remove the brake light switch and check that it is operating correctly:
Connection continuity Connection insulation
Switch pressed
(Brake pedal released)AP10 and 5A AP10 and 65A
Switch released
(Brake pedal depressed)AP10 and 65A AP10 and 5A
–Replace the switch if necessary.
Intermediate connector R107 and component 160 and 1081 disconnected:
–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.
If the connector is faulty (see NT6015, Repairing electrical wiring, wiring:
Precaution for repairs), repair the connector or the wiring, otherwise replace the
wiring.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
