1.) What kind of interface do I need ? The software works with all ISO-9141-2-/ISO-14230-1-compliant (K/L- and KK/L-) interfaces, that serve as simple voltage level converters ("Dump"-interface) or have a "pass-through"-mode.
The interface must be selectable through a serial port, which also includes USB-interfaces whose driver provides a virtual serial port (e.g. interfaces with
FTDI-USB-chip).
This is a (incomplete) list of interfaces that should work with FreeSSM (no guarantee !):
- all interfaces that work with VW-Tool and VAG-COM up to version 311.3 (409)
-
openPort-interface 1.2/1.3 (not 2.0 !)
- interfaces with AGV2055, AGV3000, AGV3001, AGV3100, AGV4000, AGV4500 chipset that provide a switch to activate the "transit mode" (e.g. OBD-Diag®-interfaces)
- "Jeff Noxons" interface (-design)
- "Andy Whitakkers" interface (-design)
Interfaces with
ELM-chip (ELM320, ELM322, ELM323, ELM327) will not work, because they use a fixed AT-command-set which is not compatible with the SUBARU®-specific protocol.
