Steer Angle Sensor

How to Replace the Steer Angle
Sensor
The steer angle sensor, installed on the steer yoke,
is monitored by the control system to determine
steer angle. The control system uses the steer
angle input, along with pre-programmed
parameters, to vary the speed of each drive motor
while steering to minimize tire scrub and to help
minimize turning radius. Drive speed is also
reduced proportionately depending on the steer
angle to minimize lateral platform acceleration.
1 Adjust the steer tires so they are in a straight
driving position.
2 Turn the key switch to the off position.
3 Push in the red Emergency Stop button to the
off position at both the ground and platform
controls and turn the key switch to the off
position.
4 Remove the cable clamp securing the steer
sensor cable to the chassis.
5 Tag and disconnect the steer sensor harness
from the main harness.
6 Remove the steer sensor cover.
