ET017BRAKE 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

RZ001Fault memory This command is used for clearing the computer's stored faults
RZ011Sensor offsetsThis command reinitialises programming of the ESP sensors.
Run this command each time an operation required the steering
wheel angle to be programmed or following any operation on the
axle assemblies.
Also run this command when the combined sensor has been
removed or replaced
SC001Check target teethThis command tests the condition of the teeth on each wheel.
Select the command SC001 and follow the instructions.
The test result should indicate 48 teeth.
SC006Bleed the hydraulic unit and
brake circuitsThis command should only be used if an abnormally long brake
pedal travel is noted during a road test with ABS control (the
system must have been bled beforehand by the usual method).
Select command SC006 and follow the instructions given by the
diagnostic tool.

Ignition on, engine stopped and vehicle speed zero.
The previous four commands allow the hydraulic check of each wheel.
Raise the vehicle in order to be able to rotate the wheels, and check that they rotate freely.
Keep the brake pedal depressed to prevent the wheel being tested from being turned (do not brake so firmly that
full brake power is reached).
Select and confirm the command of the wheel being examined (e.g. Front left-hand wheel solenoid valves, etc.)
Turn the wheel concerned by hand to see it go through several locking/unlocking cycles.
