OBD-II provides additional information to engineer for diagnosis and repair of emissions related problems.
OBD-II, standardizes on the amount of memory (Freeze Frame) it uses to store the readings of the vehicle sensor when it
logs on emission related Intermittent Trouble code (IT). The intent of OBD-II, systems is to detect most vehicle
malfunctions when performance of a power train component or system deteriorates to the point that the vehicle’s HC
emission exceed standard. The vehicle operator is notified at the time when the vehicle begins to marginally exceed
emission standards, by illuminating the Malfunctions Indicator Light (MIL).

We have kept IJCERT is a free peer-reviewed scientific journal to endorse conservation. We have not put up a paywall to readers, and we do not charge for publishing. But running a monthly journal costs is a lot. While we do have some associates, we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
