Testing the CAN bus (continued)
3. Locate the CAN bus isolation module and disconnect it from the machine
wire harness. Check the module and the harness connector for damage or
corrosion and clean or repair as necessary.

4. Set the key switch to the O
N
position.
5. Use a multimeter (DC voltage setting) to check for 12 VDC across terminals
A and B of the machine wire harness connector. If no voltage is present,
check the wire harness for damage; refer to
Appendix A (page A–1)
.
Note:
There is not a test procedure for the isolation module. Continue
testing the remaining components of the CAN bus before replacing the
isolation module.
6. Set the key switch to the O
FF
position.
7. Use a multimeter (ohms setting) to measure and record the resistance of
CAN A across the machine wire harness connector terminals C and D, and
CAN B across terminals E and F.
• A reading of 0 to 50 ohms indicates one of the devices (nodes) on the
CAN side being tested is faulty; refer to
Testing Devices (Nodes) on the
.
• A reading of 55 to 65 ohms indicates the CAN side being tested is intact.
• A reading of 110 to 140 ohms indicates one of the CAN terminator resistors
on the CAN side being tested is not connected or damaged; refer to
bus Terminator Resistors (page 5–101)
.
• A reading of 100K to 200k ohms indicates both of the CAN terminator
resistors on the CAN side being tested are not connected or damaged;
refer to
CAN bus Terminator Resistors (page 5–101)
