TROUBLESHOOTING
NETWORK RESISTANCE
The network resistance must be correct for the
network to operate correctly. Depending on which
node the measurement is taken at and the method
of measurement, the resistance may be one of two
values: 121 or 61 Ohms. Any value other than these
two means something is wrong with the network.
Method 1
1. Turn off the machine.
2. Locate a CAN node location on the machine.
3. Disconnect the connector containing the CAN
wires.
4. Measure the resistance between the green and
yellow wires.
5. Depending which nodes are still connected,
resistance should be 61 Ohms of 121 Ohms.
Method 2
1. Turn off the machine.
2. Locate a CAN node location on the machine.
3. Carefully push probes into the back of the
connector containing the CAN wires.
4. Since the network remains connected in this node,
resistance should measure approximately 61
Ohms.
CAN OPEN NETWORK ISSUES
The following items include procedures to investigate a
fault related to a CAN open network.
CONNECTOR FULLY SEATED
Each node on the network has a connector for the
CAN communication wires. A loose connection could
cause a fault code error. Check each board individual
to ensure the connectors are fully seated. There may
also be other connectors within the harness that should
be checked. If the connector is not fully seated, fully
seat the connector and power cycle the machine to see
if the fault clears.
PIN FULLY SEATED
A pin within the harness side of the connector may not
be fully seated or may come loose over time causing
a fault. If the pin is not fully seated, push it back in and
power cycle the machine to see if the fault clears.
