Lowering the Vehicle

When a load is removed from the vehicle, the vehicle body is moved upward and the Actuator arm rotates downward. Switch A closes in the Auto Level Control Sensor. After an 8 to 15 second delay, switch C closes. The Vent Solenoid is energized and air is exhausted from the air shocks. As the vehicle body moves downward, the Actuator Arm is rotated back to its original position (± 1 inch), switch A opens and the Vent Solenoid is no longer energized.
