Engine speed switch
The engine speed switch is used on machines with either a Yanmar diesel
engine or Kubota gasoline engine. The engine speed switch is used as an input
for the TEC to signal the engine ECU via the CAN-bus to increase or decrease
the engine speed. When the switch is pressed and held in the forward position,
the engine speed will increase. Conversely, when the rear of the switch is
pressed, the engine speed will decrease. The engine speed switch is located on
the control arm (
).
Testing the Engine Speed Switch
1. Park the machine on a level surface, lower the cutting units, set the parking
brake, and shut off the engine.
2. Before you disconnect the engine speed switch for testing, ensure that you
test the switch and its circuit wiring as TEC input with the InfoCenter display;
refer to
Using the InfoCenter Display for Troubleshooting (page 7–28)
.
3. If the InfoCenter verifies that the engine speed switch and circuit wiring are
functioning correctly, no further switch testing is necessary.
4. If the InfoCenter determines that the engine speed switch and circuit wiring
are not functioning correctly, proceed with the test.
5. Remove the control arm covers to get access to the engine speed switch;
refer to
Disassembling the Control Arm (page 8–23)
.
6. Ensure that the key switch is in the O
FF
position. Disconnect the wire harness
electrical connector from the engine speed switch.

7. The engine speed switch terminals are identified in
and the
circuitry of the switch is shown in the
Circuit Logic Table (page 7–69)
. With
the use of a multimeter (ohms setting), test the switch functions to determine
if continuity exists between the various terminals for each switch position.
Check the continuity between the switch terminals.
