Does it read check-engine codes?
Yes. The tracker plugs into the OBD-II port, so it reads the diagnostic trouble codes the vehicle reports, with the description, a severity rating and a plain-English explanation.
Can it clear a fault code?
The app shows and tracks codes and lets you mark an issue resolved once it has been fixed. Clearing a code without fixing the fault only hides it until the next drive cycle.
How does it know my mileage?
The odometer is read from the vehicle itself, so service intervals are based on miles actually driven rather than a number someone typed in.
Does maintenance tracking cost extra?
No. Diagnostics, service reminders and the service log are included for the life of the device, like everything else.
Will it work on any car?
Any car or light truck with an OBD-II port — every vehicle sold since 1996. The range of diagnostic data available varies a little by manufacturer.
