Tesla’s air suspension is “smart” because it uses GPS information and vehicle speed to adjust suspension ride height.
Air ride and active shocks and struts will eventually fail – succumbing to either damage to or dry rot of the air spring.
Air ride systems can control vehicle ride height, passenger comfort and improve handling. How they operate and work with the rest of the systems on the vehicle is part of the embedded logic of their control system.
Air ride diagnostics can be just as complex as any ABS or fuel injection problem. The diagnostic process should start with questions about the system rather than the parts.
