Circuit/System Description

The ratchet and pawl switches are part of the rear compartment lid latch and are used by the liftgate control module to determine the state of the actuator during the process of cinching or unlatching. The ratchet and pawl switches will be inactive when the primary and secondary latches are latched. Each of the rear compartment lid latch switch signal circuits are supplied signal through a resistor and monitored within the liftgate control module. The rear compartment lid latch switches share a common ground circuit from the liftgate control module and when the switch contacts close the signal circuit goes low and the liftgate control module determines the switch to be active.
