Air Valve Block

The Air Valve Block contains 6 solenoid operated valves, an inlet valve, an exhaust valve, and one valve for each air spring. When an increase in height is required at an air spring, ECU energizes inlet solenoid valve and respective air spring solenoid valve by applying voltage to their respective Air Valve Block terminal. The solenoid valves are grounded at ground E111 through Air Valve Block terminals No. 10 and 11. When an air release is required, ECU energizes exhaust solenoid valve and respective air spring solenoid valve.
