Subaru FreeSSM OBD2 USB Data Cable (MY99+)
Subaru vehicles from MY1999 onwards, including the Legacy, Liberty, Outback, Baja, Impreza, Forester and Tribeca can be analysed using a Subaru Select Monitor (SSM). SSM 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.
SSM typically exists as a very expense piece of hardware found only at dealerships, however thanks to a few creative developers, there is software available online known as FreeSSM. Combined with a specific OBD Cable, you can customise and tweak your own vehicle at home using a Windows computer!
- USB to OBD Cable
- FreeSSM (v1.2.5) on CD
Installation is relatively straightforward, the software and drivers are included on the CD. We recommend using Windows XP due to the age of the software.
- Insert the CD
- Install the included drivers and FreeSSM
- Open FreeSSM and in the Preferences, select the correct COM Port (Can be found within Windows Device Manger, under ‘Ports’)
- Plug in the OBD Cable, turn the ignition to ON. Click ‘Test Diagnostic Interface’ to confirm operation.
Note: The last known release of FreeSSM was in 2010 (v1.2.5), as found on SourceForge. As a result the software is dated, and comes with no support or any further details. Use with caution, it is probably best used on older Subaru vehicles.
