B1671 RAM Description
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. It is open when the latch is in primary position and closed when the latch is out of primary. The OBDII code sets when the ratchet switch did not remain closed during a power cinch operation.
