The turn signal activation (earth) signals are sent to pins
7 of connector I and 30 of connector G of the Body Computer
M1
from the steering column switch unit H5.
The hazard warning lights activation signal,
on the other hand, reaches pin 34 of connector G of
M1 from the
control button in the climate control system controls H80 (or M70).
The direct supply for the climate control
system
H80 controls (or M70) arrives via the line of fuse F39
of the junction unit under the dashboard B2; pin 7 of connector
A is earthed (earth controlled by the Body Computer M1).
The Body Computer
M1 receives a specific
direct supply for the hazard warning lights via fuse line F53 of
the junction unit under the dashboard B2;
as a result, it controls
the side direction indicators
F20 (left) and F21 (rght) from
pins 2 and 13 of connector D, the front side lights F10 (left) F11
(right) from pins 38 and 39 of connector B and for the rear side lights
F30 (left) F31 (right) from pins 12 and 3 of connector D.
The (positive) signal is sent, from pin
29 of connector G of
M1, to light up the LED in the climate control
system controls button H80 (or M70).
The Body Computer
M1 is connected, via
the CAN line, to the instrument panel E50, to manage the 'direction
indicators' warning light, the buzzer and, if there are failures
in the circuit, the 'lights failure' warning light.
