Lowering the Vehicle

When a load is removed from the vehicle, the vehicle body moves upward, the actuator arm rotates downward, and the "Exhaust Signal" switch closes (located in the Electronic Level Control (ELC) height sensor). After a 17-27 second delay, the "Ground" switch closes, the exhaust solenoid is energized and air is released from the rear struts. As the struts deflate, the vehicle body moves downward and the actuator arm rotates back to the level position (plus or minus 1 inch) causing the "Exhaust Signal" and the "Ground" switches to open. The exhaust solenoid is de-energized and air is no longer released from the rear struts.
