The diagnosis information can be checked using a diagnosis tool (GST: Generic Scan Tool).

Function of OBD

The GST is connected to the diagnosis connector on the vehicle and communicates with the on-board control units to perform diagnosis. The diagnosis connector is the same as for CONSULT-III. Refer to GI-50, "Description".
