Circuit/System Description

The latch ajar switches provide a single input to the midgate control module. The switch signal circuit is supplied accessory voltage through a resistor and monitored by the midgate control module. When the midgate is opened both of the latch ajar switches close and the circuit is pulled low. The midgate control module provides an ajar signal to the body control module through the midgate ajar indicator signal circuit. The body control module supplies the signal circuit with accessory voltage through a resistor and monitors the voltage level. When the midgate is ajar the midgate control module will ground the ajar indicator signal circuit and the voltage monitored by the body control module will drop indicating the circuit is active.
