System Description
SYSTEM DESCRIPTION1. AIR SUSPENSION SYSTEM DESCRIPTION
a. The suspension control ECU operates the compressor & motor with the dryer and uses the solenoid valves to control the vehicle height by analyzing the information based on the switches, sensors and input signals.
b. Through the 4 height control sensors, the suspension control ECU detects the changes in the vehicle height that results from the number of occupants or the amount of the load. Then, the suspension control ECU controls the height control solenoid valves and the compressor & motor with the dryer in order to automatically adjust the vehicle height to a constant (normal) vehicle height.
c. Furthermore, three vehicle heights can be selected by operating the height control switch: HI, Normal and LO.
d. When the engine is shut-off, the vehicle height can be lower than the LO vehicle height by operating the access mode switch.
e. In the case such as when the vehicle is jacked up, the auto leveling function is prohibited by operating the height control OFF switch.
