The parking brake sensor is a normally open proximity sensor that is mounted
below the parking brake shaft
sensor is the tab that is on the brake shaft.
When the parking brake is not set (the brake latch is not engaged), the tab is
positioned near the target end of the parking brake sensor so that the sensor is
closed. The tab is moved away from the sensor when the parking brake is set
(the brake latch is engaged) causing the sensor to open.
The Standard Control Module (SCM) monitors the operation of the parking brake
sensor. If the key switch is in the R
(the brake latch is not engaged), the SCM parking brake sensor input LED
should be illuminated. Test the parking brake sensor and circuit wiring as a SCM
input before you perform the following testing procedure.
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 SCM input; refer to
Control Module (page
3. If the SCM verifies that the brake sensor and circuit wiring are functioning
correctly, then no more brake sensor testing is necessary.
4. If the SCM determines that the brake sensor and circuit wiring are not
functioning correctly, proceed with the following parking brake sensor testing
procedure.
5. Remove the left cover.
6. Locate the parking brake sensor
Note: Ensure that the parking brake is not set.
