A method and a control module for diagnosing an engine component function includes a comparison module comparing an in-cylinder pressure signal to a threshold and a fault indication module generating a diagnostic signal for an engine component in response to comparing. A DLP station of the present invention includes a channel-switching module for switching a channel by writing a new channel number in a DLP request frame; a mode-switching module for switching a DLP mode by writing a new mode number in the DLP request frame; and a MAC frame-generating module for generating various MAC frames including the DLP request frame. Each identity corresponds to an internet social network that is facilitated by one of a plurality of social network sites. The count operation may be an up-count operation or a down-count operation based on the second control signal.
