Lowering the Vehicle

When a load is removed from the vehicle, the vehicle body is moved upward. When the Automatic Level Control (ALC) Sensor has detected a "Car-High" state for 7-14 seconds, the Exhaust Control Switch is closed to ground. With CKT 320 grounded, the Exhaust Solenoid is energized allowing the Exhaust Valve to open. The ALC System vents into the atmosphere, lowering the rear of the vehicle. When the vehicle body reaches its original height of +25 mm (+1 inch), the Sensor opens the Exhaust Control Switch, de-energizing the Solenoid and closing the Exhaust Valve.
