range
Deactivate: The
difference
between clutch
positions
indicated by the
sensor signal
(SEPoC) and the
inverted sensor
signal ( SEPoC
INV) is normal
Activate:
Sensor signal is
short circuit to
Ubatt or sensor
supply, when at
Voltage
least one of the

FMI3 sensor signals is
or shorted
above normal

Deactivate: No
sensor signal is
above normal

Activate: 1.
Open circuit on
any of the
sensor signals is
detected when:
one of the
sensor signals is
within normal
range and the
other sensor
signal is below
normal range

open circuit detected when
both the sensor
signals are
within the normal

Activate: Both
sensor signals
are below
