2753538 - E5010 STARTING AND RECHARING - Functional description

Functional description

The ignition switch H001 is supplied directly by the battery, by the line protected by the fuse F23, housed in the engine compartment junction unit B001. When the ignition key is turned to START, the direct battery supply is provided, from pin 3 connector A of H001, to the starter motor A020, pin 1 connector A. The direct current generated by the alternator A010 (pin B+ connector B) is sent to the battery A001, passing through the motor A020. When the alternator does not turn, and so does not recharge the battery, an earth signal is sent from pin D+ connector A of A010 to the body computer node M001 (pin 6 of connector C) which, via the CAN line, switches on the 'alternator fault' warning light on the instrument panel See E1050 CAN CONNECTION LINES .
