Need to read fault codes or check a warning lamp on your Ottimo without a workshop trip?

Free to scan; the one-time $18.99 Motortune Pro adds the write features.

Adapter

14 of 19 control units — including the engine — sit on the standard OBD pins, which any ELM327 v1.5+ adapter reaches. 5 more are on the slower interior bus (MS-CAN, pins 3/11): reaching those needs an adapter with an MS-CAN transceiver, such as the OBDLink MX+ or vLinker MC+.
