The Primary Ratchet Switch must remain closed when the liftgate is fully open or between full open and closed positions. The switch will open when the liftgate is fully closed and latched. This switch indicates when the latch is in primary position. It is open when in primary and closed when out of primary. The OBDII code sets when the ratchet switch remains open during a power release operation or when the primary ratchet switch is detected open when the latch is unlatched (liftgate open).
