Why are CAN nodes not detected in my Raven Control Systems?
- CchristopherhortonAug 26, 2025
If CAN nodes are not being detected, the possible causes are: * No power to CAN nodes. * Weak or dirty power to the CAN nodes. * Water in CAN nodes. * Corrosion in CAN connections. * Broken cable to node. * Low power voltage. Verify that there is 12 volt power and ground to the CAN node's logic power. Make sure that the 12 volt power to the CAN node is coming from the switch relay that is connected to the battery. Prevent water and moisture from building up in the nodes. Disconnect and clean the CAN connections. Repair or replace the cable and verify at least +10VDC at the node.
