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.
7
Remove the tie rod pivot pin retaining
fasteners.
1 left yoke assembly
2 steer sensor cover
3 compression spring
4 steer sensor actuator
5 tie rod pivot pin
8
Use a small pry bar to move the pivot pin down
enough to clear the steer sensor assembly.
9
Remove the steer sensor actuator and spring
from the tie rod pivot pin and set aside.
Note: Inspect the steer sensor actuator to make
sure it is not broken or twisted.
