The Body Computer
M1 receives door open input signals at
pin 8 of connector D (driver's door) and pin 25 of connector E
(passenger door).
The front courtesy light
G10 is supplied
by the direct line protected by fuse F39 of the junction unit under
the dashboard B2.
The front courtesy light
G10 is controlled
by the Body Computer M1 with a timer: pin 28 of connector E of
M1 receives an analogue control signal from the three buttons on
the actual courtesy light: as a result the Body Computer M1 supplies
the courtesy lights G10, according to the battery voltage control
logic ('SBMT') described previously, providing a timed earth signal
from pins 21, 30 and 37, connector E for the three map reading lights separately.
The Body Computer
M1 is connected, via
the CAN

CAN CONNECTION LINES
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, reaches the Body Computer
M1
via
the CAN line.
