The steering home sensor is used to determine when the wheels are directed
straight ahead. The sensor acts as an input for the Toro Electronic Controller
(TEC) to determine when steering can be changed from 4-wheel steering to
2-wheel steering. This interlock system is described in the
Switch (page
5–65).
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
sensor is a target bracket attached to the left side front steering fork.
When the left side front steering fork is in the straight ahead position, a 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.
1. Park the machine on a level surface, lower the cutting deck, and shut off
the engine.
2. Before you disconnect the steering home sensor for testing, ensure that
you test the sensor and its circuit wiring as a TEC electrical input with the
InfoCenter display; refer to
(page
5–30).
3. If the InfoCenter verifies that the steering home sensor and circuit wiring are
functioning correctly, then no more steering home sensor testing is necessary.
4. If the InfoCenter determines that the steering home sensor and circuit wiring
are not functioning correctly, proceed with the test.
5. Locate the steering home sensor and target bracket on the left side front
