NG: ROLL STABILITY CONTROL
DSC/RSC OUTLINE

• The dynamic stability control (DSC)/roll stability control (RSC) HU/CM, integrating both the hydraulic unit (HU)
and control module (CM), has been adopted, resulting in a size and weight reduction.
• A combined sensor, integrating both the yaw rate sensor, roll rate sensor, forward-G sensor and lateral-G
sensor, has been adopted, improving serviceability.
• An enhanced malfunction diagnosis system, used with the Mazda Modular Diagnostic System (M-MDS), has
been adopted, improving serviceability.
RSC Operation Outline
• The dynamic stability control (DSC)/roll stability control (RSC) system monitors the signal from the roll rate
sensor and each sensor, and calculates if the vehicle may be approaching a situation where rollover is
probable. When this occurs, the DSC/RSC system applies preemptive action.
