Steer Sensors
The steer sensors measure steer angle and
communicates that information to the ground
controls ECM. The steer sensor on the ground
controls side of the machine at the square-end acts
as the lead sensor when in front wheel steer mode.
In rear wheel steer mode, the steer sensor on the
ground controls side of the machine at the
circle-end acts as the lead sensor. The other three
sensors follow the position, or steer angle, of the
lead sensor. There is a steer sensor mounted to the
top of each steer yoke upper pivot pin.
How to Replace a Steer Sensor
Note: When the steer sensor is replaced, both the
sensor and magnet must be replaced as a set.
Note: Perform this procedure with the axles fully
retracted and the boom in the stowed position.
1 Align the remaining wheels on the machine so
they are visually parallel to the chassis as
close as possible.
2 Disconnect the steer sensor assembly cable
from the main harness to be replaced.
3 Remove the steer sensor cover retaining
fasteners. Remove the steer sensor assembly.
Note: If the sensor activator pin needs to be
replaced, install the new activator pin per Illustration
1.
