Here, we’ll talk about SSM3 and SSM4 working for Allscanner Vxdiag Subaru


What is SSM?

SSM, the short form of Subaru Select Monitor, is an OBD based tool that allows configuration and customisation of the Engine Control Unit (ECU) and Transmission Control Unit (TCU), which is great for diagnostic and tuning purposes. It can be used for Subaru vehicles from MY1999 onwards, including the Legacy, Liberty, Outback, Baja, Impreza, Forester and Tribeca.


What is SSM3?

SSM3 software is designed to work for model years 1998-2016 using Hitachi HDS3000 or the newer Denso DST-i. It doesn’t work at all with standard OBD2 devices.


What is SSM4?

SSM4 works with model years 2016+ and it’s designed to work with the Denso only.
