above 600 rpm, the clutch
position is more engaged
than the slip point and the
engine speed is received
from the engine ECU and
above 600rpm
A forward gear is engaged
in the gearbox and the main
shaft speed sensor (SESM)
indicates forward movement
or A reverse gear is
engaged and the main shaft
speed sensor (SESM)
indicates reverse
movement.
The fault is also deactivated
if the main shaft speed
sensor (SESM) signal is not
within normal range, or if
there is an active fault on
any of the sensors:
-The sensor for the
countershaft speed (SECS)
-The sensor for the clutch
position (SePoC)
-The sensor for the position
of the split cylinder (SePoS)
-The sensor for the position
of the shift cylinder (1R
SEPo1R)
-The sensor for the position
of the shift cylinder (23
SEPo23)
-The sensor for the range
cylinder (SEPoR)
