CAN–bus Terminator Resistors
System communication between various electrical components on Outcross
9060 machines is accomplished on a CAN−bus communications network. 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). A 120 ohm termination resistor is located
at each end of the CAN–bus.
One resistor is part of a short harness plugged into the platform wire harness
#2 expansion port (external) and is replaceable separately. The expansion port
is located near the rear attachment electrical connector below the right rear
corner of the operator platform.
The second CAN−bus termination resistor is part of the Yanmar engine ECU
(integrated) and can be tested as part of the CAN−bus wiring. The integrated
termination resistor is not replaceable separately.
Note:
Refer to
Appendix A (page A–1)
for additional information on the
CAN−bus wiring.
IMPORTANT
Both terminator resistors are required for proper electrical system
operation.

Keyway
1. One terminator resistor is external (plugged into the platform wire harness #2
expansion port located near the rear attachment electrical connector below
the right rear corner of the operator platform). Locate the external termination
resistor and unplug it from the wire harness for testing.
The insulator wedge in the external termination resistor is blue for
identification purposes. There also is a center keyway to prevent the
termination resistor from plugging into the wrong wire harness connector.
A. Make sure that key switch is OFF and key is removed from switch.
B. Use a digital multimeter (ohms setting) to measure the resistance
value for the external termination resistor. There should be 120 ohms
resistance between terminals A and B.
C. If testing determines the external termination resistor is faulty, replace
the resistor.
D. After testing is complete, make sure the external termination resistor is
fully installed into the connector and secured to the wire harness.
