Code B2419 Mercury Description

When the power liftgate moves in the close direction, the Liftgate/Trunk Module (LTM) monitors the pinch strips and motor position sensor for obstacle detection. If the LTM detects an obstacle, it reverses the power liftgate. The LTM monitors the left and right pinch strips and if either pinch strip is pressed the LTM reverses the power liftgate. The LTM monitors the position sensor feedback for position and movement. If the LTM is unable to determine the liftgate position or the movement indicates an obstacle the LTM reverses the power liftgate. The LTM also monitors the power liftgate latch status once the liftgate closes to a secondary latch position. If the liftgate is unable to obtain a primary latch position the LTM aborts the power close.
