Shorted to
supply
5V
Act as if in Out of
Stowed
position
*elevated drive speed
*no elevated drive due
to
tilt drive cutout on CE
units
Driving at 2 MPH is
allowed if primary and
secondary
angle sensors are
calibrated
and the mV value is
close to the calibrated,
stowed value.
Verify:
*5V from TCON C19-8
thru
C3-15 to sensor C15-C
*Verify B- from C19-9
thru C3-16 to C15-A
*Signal Output
approximately 1000 -
4000 mV across range
of motion at
TCON C19-10 GY thru
C58-5 from C15-B
(C124 SBS RD/WH)
*Cycle Power with
problem
corrected to clear fault
To Calibrate:
Stowed mV must be
between 3600 & 4400
mV
Elevated mV must be
between 600 &
16 Sensor at Zero 0V
