Common Errors and Fixes
Holley Terminator X cannot detect USB CAN device
Symptom: The software opens, but your ECU or USB CAN adapter does not appear as connected.
Likely Cause: USB passthrough is not assigned to the Windows 11 ARM virtual machine.
- 1. Open your VM settings and confirm USB device passthrough is enabled.
- 2. Reconnect the USB CAN adapter and attach it to Windows (not macOS).
- 3. Re-run iCANDrivers installer inside Windows and reboot the VM.
- 4. Launch the tuning software again and verify COM/USB device detection.
Holley Terminator X opens but fails to connect to ECU
Symptom: You can start the app, but live data and ECU sync fail or time out.
Likely Cause: Incorrect communication selection, unstable power on ECU side, or cable/port quality issue.
- 1. Confirm ECU and adapter power are stable before opening software.
- 2. Use a short, direct USB cable and avoid passive hubs.
- 3. Select the correct communication interface in software settings.
- 4. Try a second USB port on MacBook Pro M5 and retry ECU handshake.
iCANDrivers installer runs but setup does not complete
Symptom: Installer exits early, or software still behaves as if no driver is installed.
Likely Cause: Security policy, antivirus interference, or stale prior install state.
- 1. Close tuning software before running the installer.
- 2. Run installer as Administrator in Windows 11 ARM.
- 3. Temporarily pause overly strict endpoint protection during install.
- 4. Restart Windows session after install and retest connection.
