Need to read fault codes, reset the service light or check a warning lamp on your Grand Commander without a workshop trip? Motortune turns your iPhone and an ELM327 / OBD-II adapter into a scanner for the Jeep Grand Commander (type K8): it walks every control unit it can reach, names each fault in plain language, resets the service reminder and runs guided service routines. Free to scan; the one-time $18.99 Motortune Pro adds the write features.

Adapter

9 of 14 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+.
