CAN Troubleshooting

Although the control algorithm is located within the CAN node(s), the same 
troubleshooting techniques that apply to traditional hard wired control systems still 
apply to a CANbus control network. CAN allows for modularization of the control 
system, but the behavior of the system remains the same. Flow and speed 
sensors, the control valve and any boom valves, are used in the same manner.

The following are some common causes for communication failures:

Issue

Possible 
Cause

Solution

Console or 

CANbus cannot 

find nodes

Switch Box is 

not properly 

connected

Check switched power connection.

Check the CANbus connection to the 

Switch Box and reinitialize the console 

to detect the Switch Box nodes.

Ensure console is powered on.

No power to 

Switch Box

Check chassis cable power and ground 

connections.

Weak or dirty 

power to CAN 

nodes

Verify at least +10V DC is present on 

the switched power connector.

Corrosion in 

CAN 

connections

Disconnect and clean the cable 

connections

CANbus not 

terminated 

properly

Check the CAN Terminator(s)
