NOTESUse the Wiring Diagram Technical Note for New Twingo.
Check that the connections and location of any special fittings (CB, car phone, amplifier, etc.) are not preventing
the system from working correctly.
With the ignition on, check for 12 V between connections NAM and AP5 of component 583.
Is the voltage measured correct?
YESConnectors of components 1175, 1094, 583 and intermediate union
R107 disconnected.
Check the insulation and continuity of connections 4AP and 4AH between
component 583 and intermediate union R107.
Check the insulation and continuity of connections 4AP and 4AH 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.
NOCheck the condition and position of fuse F10 (5A) in the passenger compartment fuse
box (see 81C, Fuse box).
Check the connection and condition (possible wiring damage) of the connectors of
components 583 and 1016.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Connectors of components 1175, 1094, 583 and intermediate union
R107 disconnected.
Check the insulation and continuity of connection AP5 between component 1016
and component 583.
Check the continuity and insulation of connection AP5 between component 1094
and intermediate connector R107.
Check the continuity and insulation of connection NAM between component 583
and the chassis earth (tightness, oxidation, etc.).
If the connections are faulty (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.

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.

NOTESConditions of use of the command.
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.

AC195VEHICLE SPEED SIGNAL
NOTESConditions of use of the command.
Ignition on, engine stopped and vehicle speed zero.
This command is used to generate a speed other than 0 mph (0 km/h) at the computer's vehicle speed wire output
(connection 47F) for users of that signal (radio, sunroof, power-assisted steering).
This command has no visible effect on the dashboard speedometer needle.
Radio: Switch on the radio and check that the "adjustment of volume according to speed" function is active
(see 86A, radio).
Run the command AC195. During the command, you should hear the volume of the sound increase and then
decrease.
Variable electric power-assisted steering: Start the vehicle then return to the conditions of use of the command.
Turn the steering wheel from lock to lock using command AC195, to note a variation in the assistance level.
