Diagnostics

[Insomniac]

I heard there is a open source(free) diagnostic software out there that support OBD II but requires a hardware interface along with it . Is there one that doesn't require hardware interface instead it reads it straight from the OBD II through the cable and to the computer?

As far as I know you need at least some hardware to communicate with OBD II so the "free" software can diagnoses the data from Engine Controller Module.

[accord]

The "Computer" build in any vehicle from 1996 is read only, you can fash the computer on some models in GMC products

Either I do not understand your question or U do not know what U're asking?
The HW interface is nothing but the connector (J1962) with some PINs (16).
It is the way U can read the info from the ECU.
Bluetooth implementation would be nice but I'm sure it's still in RD state :)
