NOTE: This FAQ pertains to the 1st & 2nd generation Automatic adapters only.
There are a few reasons this could happen, but it usually means that the adapter hasn’t synced with your phone via Bluetooth or your adapter isn’t plugged in properly.
Sometimes Bluetooth can appear to be on but has actually crashed in the background, so try toggling it off and back on again. Also, ensure that the adapter is firmly plugged into your car’s OBD-II port. Please see this FAQ for more on what can cause missed trips. You can also refer to our Connection Troubleshooting Guides for iOS and Android for additional troubleshooting steps.
