The lower left endgate ajar switch signal and upper right endgate ajar switch signal circuits provide input to the endgate module. These inputs are used for endgate swing latch and drop latch requests. If the endgate module detects an open on the lower left endgate ajar switch signal circuit when a drop latch request is made, or an open on the upper right endgate ajar switch signal circuit when a swing latch request is made, a DTC is set.
