Low Accumulator Pressure Warning
WARNING: This page is about a different car, the 1990 Oldsmobile Toronado, 1989 Oldsmobile Toronado, and 1988 Oldsmobile Toronado. However, it is still accessible from the selected car via links, so may be relevant.
Low accumulator pressure is detected on the loop circuit by an open between pins "C" and "E" of the pressure switch on the hydraulic unit. The pressure switch will open if pressure drops below 1500 psi (10,350 kPa). Pressure switch will automatically reset when pressure reaches 1900 psi (13,100 kPa).
