The SSMΙΙΙ is a powerful fault diagnosis device (for Subaru vehicles) that has been developed using the latest advanced technology. Used in combination with a PC, it provides a tool for quick and efficient analysis of vehicle faults.

Application software running on a PC provides an interactive user interface for very simple operation. High-speed communication with the engine control system and transmission control system help to make checking of various phenomena faster than ever before.

The SSMΙΙΙ is a fault diagnosis device that provides a standard means of automotive fault diagnosis. It communicates with the various system control modules equipped in a vehicle to monitor control module input/output data, and to allow checking and deletion of diagnostic codes generated by the controlmodule. It also provides means to reset control module learning values and other control parameters, and to force operation of engine control system actuators.
