Engine Speed Switch (Yanmar Diesel Engine Only)
The engine speed switch is located on the console arm
(Fig. 38). The engine speed switch is used as an input
for the engine control unit (ECU) to raise or lower the en-
gine speed. By momentarily tapping the switch, the en-
gine speed can be increased or decreased in 100 rpm
increments. By holding the switch down the engine RPM
will automatically increase or decrease to the set High
or Low idle speed, depending on which end of the switch
is depressed. The current engine RPM will be displayed
on the InfoCenter screen for five seconds when the en-
gine speed switch is depressed.
The engine speed switch is an input used by the Toro
Electronic Controller (TEC) to manage various machine
functions.
Testing
The engine speed switch and its circuit wiring can be
tested as a TEC input using the InfoCenter Display (see
InfoCenter Display in this chapter). If testing determines
that the switch and circuit wiring are not functioning cor-
rectly, proceed with the following test procedure:
1. Park machine on a level surface, lower cutting units,
engage parking brake and stop engine. Remove key
from ignition switch.
2. Remove console arm covers to gain access to en-
gine speed switch (see Console Arm in Chapter 8 −
Chassis).
3. Disconnect wire harness electrical connector from
the engine speed switch.
4. The switch terminals are marked as shown in Figure
39. With the use of a multimeter (ohms setting), the
switch functions may be tested to determine whether
continuity exists between the various terminals for each
position. Verify continuity between switch terminals.
5. Replace switch if testing identifies a faulty switch.
6. If switch tests correctly and circuit problem still ex-
ists, check wire harness (see Electrical Schematics and
Wire Harness Drawings in Chapter 10 − Foldout Draw-
ings in this manual).
7. After testing is completed, connect wire harness
connector to the switch.
8. Assemble console arm (see Console Arm in Chap-
ter 8 − Chassis in this manual).
