Frequently asked questions

Everything you need to know about getting started with Koder Auto.

What hardware do I need?

You need any standard ELM327 Bluetooth OBD-II adapter. They are widely available and typically cost US$10–30. Koder Auto supports all ELM327 revisions.

Which cars are supported?

All gasoline cars from 1996 onward and diesel cars from 2004 onward support OBD-II. Koder Auto handles ISO 15765 (CAN), ISO 14230 (KWP2000), ISO 9141, and SAE J1850 protocols automatically.

Can I clear my Check Engine light?

Yes. Koder Auto can read and clear Diagnostic Trouble Codes (DTCs) with plain-text descriptions explaining what each code means and common causes.

Does it work offline?

All OBD-II telemetry and trip logging work completely offline. Navigation requires map data to be downloaded once — after that, it works without any internet connection.

Is my driving data private?

Your data stays on your phone by default. Optional cloud sync is end-to-end encrypted — nobody except you can read your trips, locations, or vehicle data.

Which platforms does it support?

Koder Auto runs on Android and iOS. Desktop companion apps for Linux, macOS, and Windows are on the roadmap.
