How does the self leveling suspension system work?
The earlier system using the electro-hydraulic pump will not be dis- cussed. The self-leveling suspension system is designed to maintain vehicle ride height under loaded conditions. The system is fully hydraulic, utilizing a tandem oil pump to supply pressure to both the suspension system and power steering system.
How to measure suspension level control control calibration?
Wait until the car goes into 2 different levels. Measure the heights from wheel center to the lower edge of the fender (see comments ). Enter the ACTUAL MEASURED VALUE FROM THE CAR in “new value” in Millimeters into Channel 01. Measure the heights from wheel center to the lower edge of the fender (see comments ).
How does Electronic Suspension Control ( ESC ) work?
The electronic suspension control (ESC) system independently controls each of the four shock absorbers to control the vehicle’s ride characteristics. The ESC system is capable of making these changes within milliseconds. It uses sensors like the steering angle, pitch/yaw and brake pedal sensors to determine the correct dampening force.
Where is the self leveling system fluid marked?
The self-leveling system fluid type is always marked on the top of the hydraulic reservoir. Always use the correct fluid never mix with another fluid. When filling the system, be aware of the status of the level control system. If the vehicle is loaded, the level will appear to be low. Do not fill the system unless it is in the resting state.
