CAN

CAN/CAN-FD is an industry-standard vehicle bus protocol designed for reliable ECU communication in automotive applications.

IMPORTANT

All features described in this section require a CAN DBC file. For more information about DBC files, please refer to our database documentation.

NOTE

Supported Hardware:

Manufacturer	Protocols
PEAK	CAN, CAN-FD
KVASER	CAN, CAN-FD
ZLG	CAN, CAN-FD
Toomoss	CAN, CAN-FD (Coming Soon)

Device Configuration

For demonstration purposes, we'll use a simulated device. You can configure the baud rate and sample point in the device settings.

Interactive Mode and Node Scripts

EcuBus-Pro offers two primary methods for CAN communication:

• Interactive Mode: For manual frame transmission
• Node Scripts: For automated communication using custom scripts

Interactive Mode

Each frame can be configured for periodic transmission or manual triggering (single-shot or key-bound).

You can add frames in two ways:

• Manual frame configuration
• Import from DBC database

Node Scripts

Nodes can be configured with UDS capabilities (tester) and custom scripts.

Example script for periodic signal updates:

import {setSignal} from 'ECB'
let val = 0;
// Update signal value every second
setInterval(() => {
    setSignal("Model3CAN.VCLEFT_liftgateLatchRequest", (val++) % 5);
}, 1000);
