NOTESSpecial notes:
Even though this is stored in the computer, this fault does not cause the warning lights
to come on or a fault message, because the ESP system is not faulty.
Perform fault finding on the UCH (Passenger compartment connection unit) using the
diagnostic tool.
Note:
After repairing the fault in the UCH (Passenger compartment connection unit), clear the
fault memory in the ESP system.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started.
Run a check on the UCH (Passenger compartment connection unit) using the diagnostic tool (see 87B,
Passenger compartment connection unit).
Run a multiplex network test (see 88B, Multiplex).

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