See the modules in your vehicle
With an ELM327-based BLE OBD2 adapter, CarCoding scans the vehicle’s modules, reads fault codes from those it can reach and explains every code in plain language. Which modules are reachable depends on the make and on the vehicle. The app is free to download.
Some advanced features require an in-app purchase.
Data source: the CarCoding ECU scan map (ecuDatabase.ts). The addresses and names in the table are definitions from the map; they can differ depending on the hardware and software version in your vehicle.
