Parking Brake Sensor - Toro 04384 Service Manual

Parking Brake Sensor

The parking brake sensor is normally closed and opens
when the operator applies the parking brake. If the func-
tional control lever is moved out of the NEUTRAL posi-
tion and the parking brake is applied, the engine will stop
running. The sensor and its electrical connector are lo-
cated directly under the operator floor plate (Fig. 20).
Testing
1. Park machine on level surface, lower cutting units,
stop engine, apply parking brake and remove key from
ignition switch.
2. Disconnect electrical connector from the parking
brake sensor.
3. Check the continuity of the sensor by connecting a
multimeter (ohms setting) across the connector termi-
nals.
4. With the parking brake applied, there should not be
continuity across the sensor terminals.
5. Release the parking brake. There should be conti-
nuity across the sensor terminals.
6. Replace parking brake sensor if testing determines
that it is faulty.
7. After testing is completed, connect sensor electrical
connector. Reset the parking brake.
