323000432 - E5010 IGNITION AND RECHARGING - FUNCTIONAL DESCRIPTION

FUNCTIONAL DESCRIPTION

The function is, in the main, managed by the Body Computer M001.The exchange of the D+ signal between the Body Computer M001 and the alternator A010 takes place along the line that leaves pin 25 of connector D of M001 and reaches connector B of A010.The Body Computer receives a power supply from the battery, via the line protected by fuse F1 located in the engine compartment junction unit B001. It also receives an ignition-controlled power supply (INT) from the ignition switch H001. The reference earth reaches pins 10 and 19 of connector A of M001.The Body Computer M001 also converses via the CAN with the instrument panel E050 to manage the turning on of the dedicated warning light and to converse with the other network nodes.The ignition switch H001 receives a power supply from the battery at pin 2 of connector A via the line protected by fuse F3 located in B001. The ignition switch H001 then sends the signal for activating the starter motor (if the key is turned to the extreme "AVV" (starting) position) from pin 3 of connector A via the line passing through the engine compartment junction unit until reaching A020.The starter motor A020 (30, connector A) receivers a power supply from the battery A001 (connector B). The direct current produced by the alternator A010 (B+, connector A) is sent along the line which connects connector A of A010 with connector B of A020.
