Testing the CAN–bus Terminator Resistors (continued)
Electrical System: Electrical Component Testing

1. Dash cover
2. Engine ECU
2. One CAN−bus termination resistor is integrated into the Yanmar engine ECU.
A. Make sure that key switch is OFF and key is removed from switch.
B. Unplug the external terminator resistor from the platform wire harness
(located near the rear attachment electrical connector below the right rear
corner of the operator platform).
C. Locate and remove the cap from the Yanmar SA-D connector.
D. Use a digital multimeter (ohms setting) to measure the resistance value
for the integrated termination resistor. There should be 120 ohms
resistance between terminals 2 and 3 of the Yanmar SA-D connector.
E. If testing determines the integrated termination resistor is faulty, replace
the engine ECU; contact an Authorized Toro Distributor for assistance.
F. After testing is complete, install the SA-D connector cap, and make sure
the external termination resistor is fully installed into the connector and
secured to the wire harness.
3. If the resistors test correctly and a circuit problem still exists, check the
remainder of the CAN–bus; refer to
Authorized Toro Distributor for assistance.
