COURTESY LIGHTS - Functional description

3-door

Functional description

The Body Computer M1 receives the 'door open' input signals at pin 8 (left door) and pin 25 (right door) of connector E.

On the basis of the timing and control logic described previously, the Body Computer M1 supplies the two courtesy lights:

• from pin 23 of connector E it supplies the front courtesy light G10; from pin 21 of the same connector it supplies the earth signal for the timer;
• from pin 33 of connector E it supplies the rear courtesy light G20; from pin 37 of the same connector it supplies the earth signal for the timer;

The Body Computer M1 is connected, via the CAN line, to the instrument panel E50, from which it receives the 'inertia switch operated' signal which lights upt the courtesy lights and sends a signal which, if necessary, can light up the 'doors open' warning light.

The 'low battery voltage' signal which switches off the courtesy lights if they are on also arrives via the CAN See E1050 CAN CONNECTION LINES.

• from pin 33 of connector E it supplies the rear courtesy light G20; from pin 37 of the same connector it supplies the earth signal for the timer;

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

The 'low battery voltage' signal which switches off the courtesy lights if they are on, always arrives via the CAN See E1050 CAN CONNECTION LINES.
