Any information on electronic suspension operation welcome.

I'm a technician looking for information (general or OEM specific) about electronic suspension systems. I don't have access to dealer info right now if anyone can help it would be greatly appreciated.

What kind of electronic suspension systems? Airbags? Shocks/struts that firm up based on compression amount? Magnetic fluid systems that adapt to compression rate and level?

What type of information are you looking for? The mechanism that causes them to alter their characteristics? The amount of current they draw? The cost to replace them? If they can be overridden and replaced with standard systems?
