NOTESSpecial notes:
This fault is declared present when the supply voltage of
the computer is less than the minimum operating voltage
(10 V < minimum battery voltage < 16 V).
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 fuses F1 and F2 (40A and 30A) in the engine fuse box and fuse F10 (5A) in
the passenger compartment fuse box (see 81C, Fuse box).
Check the connection and condition (for possible wiring damage) of the connector of components 1094, 1834
and the 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.).
With the connectors of component 1094, 1175, 583 and intermediate connector R107 disconnected, check
the insulation and continuity of connection AP5 between component 1094 and intermediate connector R107.

component 1016.
With the connectors of components 1094 and 1834 disconnected, check the continuity and insulation
of connection BP14 between components 1094 and 1834.
With the connectors of components 1094 and 1834 disconnected, check the continuity and insulation
of connection BP8 between components 1094 and 1834.
If the connection(s) are faulty (see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions
for repair), repair the wiring, otherwise replace the wiring.

ALP1 No dialogue with the ABS/ESP computer
NOTESOnly address this customer complaint after a complete check with the diagnostic tool.
Use the Wiring Diagram Technical Note for New Twingo.
Try to establish dialogue with an ESP computer on another vehicle to make sure that the diagnostic tool is not
faulty. 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 tightness and condition of the battery terminals (see 80A, Battery).
Check the charging circuit (see 16A, Starting - Charging).
Check that the power supply to the diagnostic socket is correct:
Check for + 12 V on connection BP19 of component 225.
Check for earth on connections MAM and NAM of component 225.
If the connections are faulty (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Apply the fault finding procedure for specification 1. DEF of fault DF001 Computer supply.
Carry out fault finding on the multiplex network using the diagnostic tool (see 88B, Multiplexing).
If dialogue has still not been established after these checks, contact Techline.
