Raising the Vehicle

When a load is added to the vehicle, the vehicle body is moved downward. When the Automatic Level Control (ALC) Sensor has detected a "Car-Low" state for 7-14 seconds, the Intake Control Switch is closed to ground. With CKT 321 grounded, the coil in the Compressor Motor relay is energized and the relay contacts close. Battery voltage is applied to the Compressor Motor, which operates the Compressor and pumps air into the adjustable shock absorbers. As the shocks extend, the rear of the vehicle rises. When the vehicle body reaches its original height of +25 min (+1 inch), the ALC Sensor opens the Intake Control Switch, de-energizing the Relay coil and the Compressor Motor stops.
