The parking brake sensor is a normally open proximity sensor that mounts to
the brake lever assembly
is the parking brake detent.
The machine is equipped with an interlock switch on the parking brake. The
engine shuts off if the traction control pedal is moved from the N
with the parking brake engaged. Refer to the Safety Interlock System in the
Traction Unit Operator's Manual.
When the parking brake is not set (the brake latch is not engaged), the parking
brake detent is positioned near the target end of the parking brake sensor so
that the sensor is closed. The parking brake detent is moved away from the
sensor when the parking brake is set (the brake latch is engaged) causing the
sensor to open.
The Toro Electronic Controller (TEC) monitors the operation of the parking
brake sensor.
1. Park the machine on a level surface, lower the cutting deck, and shut off
the engine.
2. Before you disconnect the parking brake 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 brake sensor and circuit wiring are
functioning correctly, then no more brake sensor testing is necessary.
4. If the InfoCenter determines that the brake sensor and circuit wiring are not
functioning correctly, proceed with the test.
5. Locate the parking brake sensor
Note: Ensure that the parking brake is not set.
