baud rate 9600? not sure about this specific device, but elm327 can operate in 9600 or 38400, maybe try the latter? And the "raw" protocol supports 4800, 9600, 10400 and various other (see e.g. http://www.obdtester.com/obd2_protocols , but you would have to dig further, I don't remember exactly and I'm not even sure you should use these when connecting via elm327 and/or bluetooth)
