Standard Control Module (2Wd Machines) - Toro Groundsmaster 360 Service Manual

Standard Control Module (2WD Machines)

Groundsmaster 360 machines with 2WD are equipped
with a Standard Control Module (SCM) to monitor and
control electrical components required for safe opera-
tion. The SCM is attached to the frame under the opera-
tor seat (Fig. 52).
Inputs from the ignition, neutral, parking brake, PTO,
seat, high temperature warning and high temperature
shutdown switches are monitored by the SCM. Current
output to the PTO, engine starter motor and engine run
components (fuel pump and engine run solenoid) are
controlled based on the inputs monitored by the SCM.
The SCM can be used to check operation of machine
switches by monitoring the SCM LED's. If a SCM LED
does not illuminate (e.g. the In Seat input LED does not
illuminate when the seat is occupied and the ignition
switch is in the RUN position), testing of the switch,
fuses and circuit wiring would be required.
The SCM does not connect to an external computer or
hand held device, cannot be re--programmed and does
not record intermittent fault data.
SCM Inputs (Fig. 53)
The Power input LED should be illuminated when the
ignition switch is in the RUN position. The Power input
LED should also be illuminated when the ignition switch
is in the START position.
The Start input LED should be illuminated when the igni-
tion switch is in the START position.
The Neutral input LED should be illuminated when the
traction control pedal is in the neutral position.
The Parking Brake Off input LED should be illuminated
when the parking brake is not applied.
The PTO Switch input LED should be illuminated when
the PTO switch is on (pulled out).
The In Seat input LED should be illuminated when the
operator is sitting in the seat.
The High Temperature Shutdown input LED should be
illuminated when the engine high temperature shut-
down switch closes due to engine coolant temperature
o o
of 240 F (115 C) (approximate).
The High Temperature Warning input LED should be il-
luminated when the engine high temperature warning
switch closes due to engine coolant temperature of
o o
220 F (105 C) (approximate).
The Backlap input LED is not used on the Groundsmas-
ter 360.
Electrical System
SCM Outputs (Fig. 53)
The Start output LED should be illuminated when the
ignition switch is in the START position with the traction
control pedal in the neutral position, the PTO switch OFF
and either the seat occupied or parking brake engaged.
The Run output LED should be illuminated when the
ignition switch is in the RUN position and inputs from the
neutral, parking brake, PTO, seat and engine coolant
temperature switches indicate safe engine operation
(e.g. seat occupied and parking brake disengaged when
the traction control pedal is moved from the neutral posi-
tion).
The PTO output LED should be illuminated when the
ignition switch is in the RUN position and the PTO switch
is ON (pulled out). NOTE: If the SCM High Temperature
Warning input LED is illuminated, PTO output LED will
not be illuminated and PTO will be disengaged regard-
less of PTO switch position.
