AXLE AR-CENTER 3693747 - Caterpillar

Problem-Remote CAN Network receives no data from Local CAN Network
Probable Cause
Confirm the PL1000T is properly connected to system power. Confirm the key switch circuit has Batt+ applied.
Confirm all devices on the CAN networks that are connected to the PL1000T are functioning properly. Confirm all devices on the CAN networks that are connected to the PL1000T are configured for 250K baud rate.
Confirm the "J1939 Bridge Function Enable Status" on the "PL1000T Communications ECM Configuration" screen is configured to "Enabled".
Connect the service tool to the CAN network that is connected to the "CAN Port 1" of the PL1000T. Use the "Caterpillar Communications Adapter". Confirm that the devices that are connected to that network are detected. If no devices are detected, then the harnessing should be analyzed and repaired. Connect the service tool to the CAN network that is connected to the "CAN Port 2" of the PL1000T. Use the "Caterpillar Communications Adapter II". Confirm that the devices that are connected to that network are detected. If no devices are detected, then the harnessing should be analyzed and repaired.Problem-Remote CAN Network receives partial data from Local CAN Network
Probable Cause
Confirm all devices on the CAN networks connected to the PL1000T are functioning properly and configured for 250K baud rate.
Connect to Caterpillar Communication Adapter. Confirm that the devices that are connected to "CAN Port 1" of the PL1000T are detected. Confirm that the devices that are connected to "CAN Port 2" of the PL1000T are detected. If one or more devices connected to "CAN Port 2" of the PL1000T are not detected, the CAN network connection to that device should be analyzed and repaired.
Monitor the "CAN Extension Bridge Statistics" screen using the service tool. The number of messages that are received on "CAN Port 1" should equal the amount of messages that are transmitted on "CAN Port 2". A potential cause of partial data is an intermittent harness failure. The harnessing should be analyzed and appropriate repairs made.Problem-Excessive data latency from Local to Remote CAN Network
Disable all other PL1000T features. Observe the data flow. If the data flow is improved, the "CAN Buss" loading is excessive. A secondary PL1000T must be used in this system in order to enable the other features.
