The device either lost communication with the vehicle ECU or entered Listen Only mode, likely due to an installation issue. A loose device or harness connection is the most common cause.


  1. Check Engine Faults to see if there are any faults that indicate faulty installation
  2. If so, perform a hard reset by power cycling the device. Ensure the device and harness are secured.
  3. Take the vehicle on a short trip to allow the device to detect engine data again.
  4. If the problem is not resolved, contact your designated support channel for further assistance.
