CAN-bus Terminator Resistor
g291761
Figure 64
The system communication between the electrical components on the
Greensmaster eFlex machines is accomplished on a CAN-bus communication
system. The 2 specially designed, twisted cables form the bus for the networks
used on the eFlex. These wires provide the data pathways between the
machine components. At the ends of the twisted pair of bus cables are 120
ohm terminator resistors.
The resistors plug into the wire harness in the following areas:
1. On the main wire harness under the key switch, inside the handle cover.
2. On the main wire harness near the TEC controller.
Note:
Refer to the Electrical Schematic and Wire Harness Drawings in
Appendix A (page A–1)
for additional information on the terminator resistor
locations and wire connections.
IMPORTANT
The terminator resistors at the ends of the bus cables are required
for proper electrical system operation.
Testing the CAN-bus Terminator Resistor
1. The CAN-bus terminator resistor (
) can be tested using a digital
multimeter (ohms setting). Locate the CAN-bus terminator resistor and
remove the cable tie that secures the resistor to the wire harness. Unplug the
resistor from the wire harness for testing.
2. Check the resistor and resistor holder for damage or corrosion and clean
or repair if necessary.
3. Use a digital multimeter (ohms setting) to measure the resistance value for
the CAN-bus terminator resistor. There should be 120 ohms resistance
between the terminals 1 and 2.
4. If the testing determines that the CAN-bus terminator resistor is damaged,
replace the CAN-bus terminator resistor.
5. After you complete the testing, ensure that the CAN-bus terminator resistor
is fully installed into the wire harness connector and secured to the wire
harness with cable tie.
6. If the resistor test correctly and a circuit problem still exists, check the
CAN-bus; refer to
Testing the CAN bus (page 5–24)
, wire harness drawings
in
Appendix A (page A–1)
for additional information, or contact an Authorized
Toro Distributor for assistance.
