What does this module do?
The engine control unit manages fuel injection, ignition timing and air measurement; most emissions-related monitoring also runs here. The mandatory OBD-II emissions channel points at this module, which is why it is usually the easiest one to reach with a generic adapter.

Engine Control Unit on your own 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.
