ECU Serial Connection
Begin by connecting to the COMMAND ECU using the Comms tab. Select the correct COM port from the list, or click the 'Scan ports' button to search for COMMAND data among all serial ports present.
If the scan was successful, clicking on Connect will establish communications with the COMMAND ECU. A successful connection is indicated by:
- Port Connection Status = Connected,
- ECU Connection Status = Connected,
- ECU Authentication Status = Success
If Level COMMAND fails to connect to the ECU over the chosen COM port, a warning will be displayed as shown below.
If connection fails:
- Verify ECU power
- Confirm the correct COM port is selected
- Check USB or serial connections
If the ECU is detected successfully, click Connect.
Level COMMAND will:
- Establish communication with the ECU
- Read stored parameters
- Load the current machine configuration
Once connected, proceed to Profile Setup.
