Terminal

Sending commands straight to the adapter and seeing the raw answer.

The Terminal sends ELM327 commands straight to the adapter and shows the answer raw. It is the right tool for investigating a car that answers in an unusual way, and it does not replace the reading screens for everyday use.

  1. Connect first

    The screen needs the adapter connected and the ECU answering, because the commands are sent in real time.

  2. Send a command

    Type in the Please enter your command field and send. The answer appears below, exactly as the adapter returned it.

    Commands starting with AT go to the adapter; the rest are passed on to the car.

  3. Use it for what it is meant for

    The terminal serves to confirm the adapter version, to check which protocol was negotiated and to try a command that the manufacturer documentation mentions and the app does not model yet.

    To read sensors, use Live Data. To look for new sensors, use sensor discovery. Both screens do those jobs more safely.

  4. Be careful

    Write commands can change settings in the vehicle's ECU. If you do not know exactly what a command does, do not send it.


If something goes wrong

The terminal needs the ECU answering. Connect the adapter with the ignition on, through the Connection screen.

The answer means the car did not serve that command. The possible causes are a command the vehicle does not implement, a protocol other than the expected one, or an ECU that is still asleep. Make sure the ignition is on.

Turn the ignition off, wait a moment and turn it on again, so that the ECU restarts. Do not repeat the command: write commands can change vehicle settings.
