The machine controllers communicate with each other on a Controller Area
Network (CAN) bus system. Using this network allows full integration of all the
different electrical components of the machine, allowing them to operate together
as one. The CAN bus system reduces the number of electrical components and
connections used on the machine and allows the number of wires in the wire
harness to be significantly reduced.
The InfoCenter, lithium-ion battery controller (BMS - Battery Management
System), electric motor controller and TEC are on the CAN bus. Additional
controllers may be added to the CAN bus in the future through the expansion
port connector and/or the telematics connector.
Each of the components that is controlled by the CAN bus link only needs four
(4)wires to operate and communicate to the system: CAN High, CAN Low, power
and ground. The key switch needs to be in the RUN or START position for the
components on the network to be activated.
Two specially designed, twisted wires form the CAN bus. These wires provide
the data pathways between the components on the network. The engineering
term for these cables are CAN High and CAN Low. The CAN bus wires are
red/white (CAN-High) and black/white (CAN-Low). At end of the CAN bus is a
120 ohm termination resistor; refer to
CAN-bus Terminator Resistor (page 5–39)
.
The Toro DIAG electronic control diagnostics service system is available to
Authorized Toro Distributors to support machine fault diagnosis and maintenance
services of the machine electrical control devices. The Toro DIAG connector is
located inside the upper cover assembly; refer to
