FUNCTIONAL DESCRIPTION

The Body Computer M001 - connector A - receives a direct power supply from the battery through the line protected by maxi fuse F01 of the engine compartment junction unit B001.

Pin 9 of connector E of M001 provides the Body Computer with a reference earth.

The ignition switch H001 is supplied by the engine compartment junction unit B001 via the line protected by fuse F03.

In the MAR-ON position, numerous protected ignition-operated circuits and services are supplied (INT and 15/54 lines): the ignition-operated signal 15/54 is sent to the engine compartment junction unit B001, whilst the INT signal is sent to the Body Computer M001, to pin 11 of connector E.

The ignition-operated signal INT/A, however, is sent to Body Computer M001 at pin 1 of connector E.

When the ignition key for switch H1 is turned to the extreme position (AVV) pin 50 - the starter A020 solenoid winding is supplied - pin 50.

Pin 30 of A020 - connector A - i.e. the actual motor, receives a power supply with the voltage coming directly from the battery A1.

The direct current produced 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 does not therefore recharge the battery, an earth signal is sent from pin D+ connector A of A010 to Powertrain Control Module M010 - pin 15 of connector B: this is connected via the CAN line to Body Computer M001 and to instrument panel E050 and manages, as described above, the activation of the generator warning light on the instrument panel.
