Error Response from OBD-ii (7F 01 11)

I have been extracting OBD-II DATA from UART board (ELM327) on my TOYOTA INNOVA. It responded correctly few weeks before and gave all supported sensor values. But now, for every response, ECU responds "7F 01 11". Please tell me what exactly this output means and how to get rid of this problem.

7F is the general fail response.

11 means: Service Not Supported.

So that is what it means. However it seems strange as it was working before. Did you change any setting of the ELM327 module? If so, it could be possible to reset all settings.
