1. Parking brake switch
The parking brake switch is a normally open switch. The Electronic Control Unit
(ECU) monitors the operation of the parking brake switch.
The parking brake switch located under the operator's platform.
When the parking brake is not set, the parking brake bracket is away from the
target end of the parking brake switch so that the switch is open. When the
parking brake is set, the parking brake bracket is positioned on the target end of
the parking brake switch so that the switch is closed.
1. Park the machine on a level surface, lower the cutting deck, shut off the
engine and the key switch is in the OFF position.
2. Locate and disconnect the machine wire harness connector from the parking
brake switch (Figure
3. Connect a multimeter (ohms setting) across the switch connector terminals
to check the continuity of the switch as follows:
A. With the parking brake disengaged, there should be no continuity
between the switch terminals.
B. Engage the parking brake, there should be continuity between the switch
terminals.
4. Replace the switch if testing determines that the switch is damaged.
5. If the parking brake switch testing is correct and a circuit problem still exists,
check the main wire harness; refer to the Electrical Schematics and Wire
Harness Drawings/Diagrams in
6. After you complete the reverse switch testing, connect the switch connector
to the machine wire harness.
