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.
Check the insulation and continuity of connection AP5 between intermediate connector R107 and
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.
