The ignition-operated power supply (INT) of the instrument panel
E50
reaches
pin 1 of connector A through the line of fuse F37 of the unit under
the dashboard
B2
; the direct supply reaches pin 2 of connector
A through the line of fuse F53 of the unit under the dashboard
B2
;
pin 7 of connector A is earthed (earth controlled by the Body Computer
M1
).
The instrument panel
E50 is connected
from pins 3 and 4 of connector A to the Body Computer M1 and via
the latter to the whole CAN network: via CAN the signal for the electronic
speedometer arrives (coming from the ABS control unit M50): this
signal is replicated from pin 16 of M50 to pin 7 of connector A
of the Body Computer M1.
The electronic rev counter receives the
rpm signal coming via CAN from the engine management control unit
M10
.
The fuel gauge is controlled in accordance
with the signals coming from the fuel gauge sender unit located
in the fuel pump assembly
N40 - at pins 4 and 15 of connector
D of the Body Computer M1, and from here via CAN to the instrument
panel E50.
The low brake fluid/handbrake applied warning
light comes on through a signal from the handbrake switch
I40
,
which reaches pin 24 of connector E of the Body Computer
M1
,
or from the signal from the low brake fluid level sensor
K25
,
which reaches pin 18 of connector A of
M1
.
All these signals are transferred via CAN
to the instrument panel
E50
.
Instrument panel
E50 also contains electronic
modules that control panel dimmed lighting and other controls
