General Information
Operator’s Manual
The Operator’s Manual provides information regarding
the operation, general maintenance and maintenance
intervals foryour Groundsmaster 4300--D machine. Re-
fer to that publication for additional information when
servicing the machine.
Toro Electronic Controller (TEC)
Groundsmaster 4300--D machines use a Toro Electron-
ic Controller (TEC) to manage machine electrical func-
tions. The controller is a microprocessor controlled
device that senses the condition of various switches (in-
puts) and then directs electrical power to control ap-
propriate machine functions (outputs) based on the
inputs. The status of inputs to the controllers as well as
outputs from the controllers can be monitored with the
Diagnostic Display (see Special Tools in this chapter).
IMPORTANT: Before performing any welding on the
machine, disconnect both positive and negative
battery cables from the battery, disconnect the wire
harness connector from the TEC controller and dis-
connect the terminal connector from the alternator.
This will prevent damage to the electrical system of
your Groundsmaster.
CAN--bus Communications
TheTECcontrollerusedontheGroundsmaster4300--D
communicates with other electrical components on a
CAN--bus communication system. The CAN--bus sys-
tem reduces the number of electrical components and
connections used on the machine and allows the num-
ber of wires in the wire harness to be reduced.
Each of the components that is controlled by the CAN--
buslinkonlyneedsfour(4)wirestooperateandcommu-
nicate to the system: CAN--high, CAN--low, B+ (power)
and ground.
IMPORTANT: The termination resistors at the ends
of the bus cables are required for proper electrical
system operation.
CAN identifies the Controller Area Network that is used
on the Groundsmaster. Two (2) specially designed,
twisted cables form the bus. These wires provide the
data pathways between machine components. The en-
gineering term for these two (2) cables are CAN--high
and CAN--low. At the ends of the twisted pair of bus
cables are 120 ohm termination resistors.
