Testing the CAN bus Terminator Resistors (continued)
resistor and the resistor holder for damage or corrosion and clean or repair
if necessary.
Note:
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.

4. If testing determines the external termination resistor is faulty, replace the
resistor.
5. After testing is complete, make sure the external terminator resistor is fully
installed into the connector and secured to the wire harness.
6. Install the operator’s console covers if previously removed.

position and remove
the key from the key switch.
2. Remove the operator’s console covers; refer to
