NOTESSpecial notes:
Even though it is stored in the computer, the ABS/ESP system is not faulty.
The ESP is deactivated following unusable information from the injection system.
Perform fault finding on the injection system using the diagnostic tool.
Note:
The injection does not always store these transient faults as quickly as the ABS/ESP.
Note:
Once the fault in the injection system has been repaired, clear the ABS/ESP computer
fault memory.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started.
Check the injection computer (see 13B, Diesel injection or 17B, Petrol injection) using the diagnostic tool.
Run a multiplex network test (see 88B, Multiplex).

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,

DEF: Abnormal voltage.
NOTESUse the Wiring Diagram Technical Note for New Twingo.
Check the tightness and condition of the battery terminals (see 80A, Battery).
Check the charging circuit (see 16A, Starting - Charging).
Check the condition and position of fuse F1 (40A) and F2 (30A) in the engine fuse box
(see 81C, Fuse box).
Check the connection and condition (possible wiring damage) of the connectors of components 1094, 1834,
1016 and intermediate connector R107.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the connector, otherwise replace the wiring.
With the connector of component 1094 disconnected, check the insulation and continuity of connections MAH
of component 1094 (tightness, oxidation, etc.).
Connectors of components 1094, 1175, 583 and intermediate union R107 disconnected,
–check the insulation and continuity of connection AP5 between component 1094 and intermediate
connector R107.
–Check the insulation and continuity of connection AP5 between intermediate connector R107 and
component 1016.
–Check the insulation and continuity of connection BP14 between components 1094 and 1834.
–Check the insulation and continuity of connection BP8 between components 1094 and 1834.
If the connections are faulty (see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.

NOTESSpecial notes:
Even though it is stored in the computer, this fault does not cause the warning light to
come on or a fault message, because the ESP system is not faulty.
Perform fault finding on the BVR (sequential gearbox) using the diagnostic tool.
Note:
After repairing the fault in the BVR (sequential gearbox), clear the fault memory in the
ESP system.
Priority in the event of a number of faults:
Deal with fault DF152 Multiplex network first if it is present or stored.
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 BVR using the diagnostic tool (see 21B, Sequential gearbox).
Run a multiplex network test (see 88B, Multiplex).

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.
