The steering home sensor is used to determine when the wheels are directed
straight ahead. The sensor acts as an input for the TEC to determine when
steering can be changed from 4-wheel steering to 2-wheel steering.
The steering home sensor is a normally open proximity sensor. The sensor
mounts to a bracket that is secured to the bottom of the front axle near the left
side front steering fork
bracket attached to the left side front fork.
When the left side front steering fork is in the straight ahead position, an oval
hole in the target bracket is positioned directly below the steering home sensor
allowing the sensor to be in its normally open state. The sensor closes when the
left side front steering fork is not in the straight ahead position.
Before performing an adjustment to the steering home sensor, ensure that the
front and rear wheels are aligned in a straight ahead position. A rigid straight
edge (e.g., angle iron or metal pipe) at least 2 m (80 inches) long can be used
to confirm the wheel alignment. Place the straight edge across the sides of
both front and rear tires to confirm the wheel alignment. The straight edge
should contact both front and rear tires at 2 points when the wheels are aligned
(Figure 192). If necessary, turn the steering wheel until the front and rear tires
are aligned with the straight edge. Once the front and rear wheels are aligned,
proceed with the steering home sensor adjustment.
Note: If the wheel alignment cannot be achieved by turning the steering wheel,
additional adjustment may be required. Refer to
1. When the wheels are in the straight ahead position, ensure that the steering
home sensor is directly over the oval opening in the target bracket attached
to the left side front steering fork. If necessary, loosen and change the
