NOTESConditions for applying the fault finding procedure to stored faults:
Apply the fault finding procedure whether the fault is present or stored.
Use the Technical Note wiring diagram for New Twingo.
1.DEF
NOTESSpecial notes: This fault will appear in a road test
(speed greater than 12 mph (20 km/h)) if the computer
supply voltage is below the minimum operating voltage
(9.4 V < min battery voltage < 10 V).
Check the tightness and the condition of the battery terminals.
Check the battery voltage and carry out any work required to obtain the correct voltage (10 V < battery voltage
< 17 V).
Check the charging circuit (see 80A, battery).
Check the condition and position of the 15A and 20A fuses in the engine fuse and relay box.
Check the condition and position of the F10 5 A fuse in the Passenger compartment fuse box.
Consult section 81C, Fuses.
Check the connection and condition (possible damage to the wiring) of the connector of component 1094.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring, wiring: Precautions for
repair), repair the connector, otherwise replace the wiring.
●Connector of component 1094 disconnected, check the insulation and continuity of connection MAH of
component 1094 (tightness, oxidisation etc.).
●Connectors of component 1094 and 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.
●Connectors of component 1094 and R67 disconnected, check the insulation and continuity of
connections BP8 and BP14 between component 1094 and intermediate connector R67.
●Check the insulation and continuity of connections BP8 and BP14 between intermediate connector R67
and component 597.
If the connection or connections are faulty (see Technical Note 6015A, Electrical wiring repair, Wiring:
Precautions for repair), repair the connectors or wiring, otherwise replace the wiring.
If the checks reveal no faults, perform a conformity check of component 597.
If all the checks are in order, reconnect the computer and clear the computer fault memory.
Exit the fault finding procedure and carry out a road test.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESSpecial notes:
If this fault appears after the computer is replaced, the pump motor connection
has been twisted. Separate the hydraulic unit from the computer and restore the
connection to working order.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after: Brake pedal held down and AC016 Test pump
motor actuator command.
Use the Technical Note wiring diagram for New Twingo.
Check the tightness and the condition of the battery terminals.
Check the condition and position of the 15A and 20A fuses in the engine fuse and relay box.
Check the condition and position of the F10 5A fuse in the Passenger compartment fuse box.
Consult section 81C, Fuses.
Check the connection and condition (possible damage to the wiring) of the connector of component 1094.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring, wiring: Precautions for
repair), repair the connector, otherwise replace the wiring.
●Connector of component 1094 disconnected, check the insulation and continuity of connection MAH of
component 1094 (tightness, oxidisation etc.).
●Connectors of component 1094 and 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.
●Connectors of component 1094 and R67 disconnected, check the insulation and continuity of
connections BP8 and BP14 between component 1094 and intermediate connector R67.
●Check the insulation and continuity of connections BP8 and BP14 between intermediate connector R67
and component 597.
If the connection or connections are faulty (see Technical Note 6015A, Electrical wiring repair, Wiring:
Precautions for repair), repair the connectors or wiring, otherwise replace the wiring.
Use command AC016 Pump motor test. If the fault is still present (no sound of the pump turning or loss of
communication with the computer), replace the entire unit (pump mechanically seized, pump short circuited, etc.).
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP 1 No dialogue with the ABS computer
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Check that the diagnostic tool is not causing the fault by trying to establish dialogue with a computer on another
vehicle. If the tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle,
the cause could be a faulty computer interfering on the multiplex network.
Check the battery voltage and carry out the necessary operations to obtain the correct voltage (9.5 V < Battery
voltage < 17.5 V, see MR411 Mechanical systems, 16A, Starting-charging).
Run fault finding on the multiplex network, using the diagnostic tool (see MR413 Fault finding, 88B, Multiplex).
Check the condition and position of the 15A and 20A fuses in the engine fuse and relay box.
Check the condition and position of the F10 5 A fuse in the Passenger compartment fuse box.
Consult section 81C, Fuses.
Check the connection and condition (possible damage to the wiring) of the connector of component 1094.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring, wiring: Precautions for
repair), repair the connector, otherwise replace the wiring.
Check that the supply to the computer is correct:
●Connector of component 1094 disconnected, check the insulation and continuity of connection MAH
of component 1094 (tightness, oxidisation etc.).
●Connectors of component 1094 and 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.
●Connectors of component 1094 and R67 disconnected, check the insulation and continuity of
connections BP8 and BP14 between component 1094 and intermediate connector R67.
●Check the insulation and continuity of connections BP8 and BP14 between intermediate connector R67
and component 597.
If the connection or connections are faulty (see Technical Note 6015A, Electrical wiring repair, Wiring:
Precautions for repair), repair the connectors or wiring, otherwise replace the wiring.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

Ensure that the supply to the diagnostic socket is correct:
Check the condition and position of the F12 5 A fuse in the Passenger compartment fuse box.
Consult section 81C, Fuses.
Connector of component 645 of connection BP19 disconnected:
–Check for + after ignition feed on connection BP19 of component 225.
If the + after ignition feed is not present on connection BP 19, check component 1016.
–Check connections NAM and MAM of component 225.
If the connection is faulty (see Technical Note 6015A, Repairing electrical wiring, wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If dialogue has still not been established after these checks, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
