If the app shows an error message when you tap “Calibrate OBD-II Device”, please follow these steps to troubleshoot.
- Start vehicle engine.
- Purchase and install DashCommand app. That’s the best OBD app that reads a whole bunch of readings from the vehicle, even engine fault codes.
- Open DashCommand > Data Grid > Add PID > DTCs > Distance since diagnostic trouble codes cleared > check it > Back > Done. It will show up on the bottom. After a few seconds, you should see a number.
- If all the other readings showed up, but the one you just added “SAE.CLR_DIST” did not show any number, that means your vehicle does not support that reading.
- If the number is 65535, which means it’s maxed out, so you need to open Diagnostics screen > Clear Codes. It will reset that reading. After reset, you need to disconnect from DashCommand, and open TripLog and re-calibrate OBD.
TripLog relies on that reading to determine the odometer. Not all vehicles support that reading. You can try this on a different car. If your vehicle does not support, unfortunately, we cannot do anything. But you can still use TripLog with other auto start options.
