What to do if eControls ECOM E2046012 CAN/SERIAL LED is flashing red and there is no communication?
- TtinaarnoldJul 25, 2025
If the eControls Cables and connectors CAN/SERIAL LED is flashing red and there is no communication, several factors could be at play: * A disconnected wire or reversed CAN-H and CAN-L wires. To fix this, resolve the wiring issue. * The eControls device software may be set to the wrong baud rate. Verify the correct baud rate for your bus and controllers, then adjust your software accordingly. * The CAN bus might need a 120-ohm terminating resistor. If so, connect a terminating resistor between CAN-H and CAN-L. * The ECOM device may be attempting to transmit a CAN packet when there is no other node on the CAN bus. Connect and activate another CAN device to resolve this.
