CAN bus
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 integration of the controllers allows the InfoCenter Display to assist
with electrical system diagnostics.
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
yellow (CAN-High) and green (CAN Low). At each end of the CAN bus is a 120
ohm termination resistor; refer to
CAN–bus Terminator Resistors (page 6–71)
.
Testing the CAN bus

1.
Main fuse block

Connector cover
2.
Toro DIAG connector
1. Make sure that key switch is OFF and key is removed from switch.
2. The Toro DIAG connector is part of the CAN bus and is located below the
dash next to the main fuse block. Locate the Toro DIAG connector and
remove the connector cover.
3. Use a multimeter (ohms setting) to measure the resistance across terminals
A and B.
• A reading of 54 to 66 ohms indicates the CAN bus is intact.
• A reading of 120 ohms indicates one of the CAN bus terminator resistors
is not connected or damaged; refer to
(page 6–71)
.
• Any other reading indicates the CAN bus wiring is damaged; refer to
Appendix A (page A–1)
or contact an Authorized Toro Distributor for
assistance.
4. Install the Toro DIAG connector after testing.
