Summary
Service Information: Introduction to electronic controlled air suspension (ELC) The electronic controlled air suspension maintains the ride height by using an electronic control unit (ECU), height sensors, pressure sensors and solenoid valve blocks. The ECU uses the information of the height sensors and the pressure sensors to determine the proper vehicle ride height. If necessary, the ECU will change the pressure within the air bags by actuating specified solenoids in the valve blocks. This Service Bulletin provides an overview.
