Toyota Electronic Modulated Suspension

TEMS (Toyota Electronic Modulated Suspension) is a shock absorber that is electronically controlled (Continuous Damping Control) based on multiple factors, and was built and exclusively used by Toyota for selected products during the 1980s and 1990s (first introduced on the Toyota Soarer in 1983). The semi-active suspension system was widely used on luxury and top sport trim packages on most of Toyota's products sold internationally.
