COURTESY LIGHTS - FUNCTIONAL DESCRIPTION

FUNCTIONAL DESCRIPTION

The Body Computer M1 receives door open input signals at pin 8 of connector D (driver''s front door) and 25 of connector E (passenger side door).

Front courtesy light G10 is operated from a direct line protected by fuse F39 of under-dashboard control unit B2.

The front courtesy light G10 is controlled by the Body Computer M1: the analogue control signal from the three courtesy light buttons reaches pin 28 of connector E of M1: the Body Computer M1 consequently supplies the courtesy lights G10, providing a timed earth signal from pins 21, 30 and 37.

The Body Computer M1 is connected, via the CAN line, to the instrument panel E50 from which it receives the "inertia switch operated" signal that lights up the courtesy lights and to which a signal that lights up the "doors open" warning light, when necessary, is sent.
