Energy Accumulator (Capacitor)
WARNING: This page is about a different car, the 1993 Mercedes-Benz 500SEL and 1993 Mercedes-Benz 500E. However, it is still accessible from the selected car via links, so may be relevant.
On 500E models, the energy accumulator or capacitor is a separate SRS component. On all other models, energy accumulator or capacitor is an integral component of SRS control unit. Capacitor is used to supply power to SRS control unit if normal power source (battery voltage) is interrupted. If capacitor fails, SRS warning light on instrument cluster will remain on.
