04 BRAKESDynamic Stability ControlDynamic Stability Control (DSC) Outline• The DSC HU/CM, integrates both the hydraulic unit (HU) and control module (CM),resulting in a size and weight reduction.• A combined sensor, integrating both the yaw rate sensor and lateral-G sensor,improves serviceability.• The controller area network (CAN) system improves serviceability and reliabilityfor the steering angle sensor.• An enhanced malfunction diagnosis system, used with the WDS improvesserviceability.DSC Operation Outline• The ABS prevents wheel lock-up during braking. The TCS detects drive wheel spindue to the accelerator pedal being pressed too hard or similar causes and controlsengine speed to suppress wheel spin. With these systems, safety is assured whendriving or stopping.• Additionally, the DSC controls sudden changes in vehicle attitude, due to evasivesteering or road conditions. The DSC suppresses vehicle sideslip when drivingdue to vehicle spin (oversteer) or drift-out (understeer) by controlling braking andengine speed. At this time, the DSC indicator light illuminates to alert the driverthat the DSC is operating due to a dangerous situation. As a result, the drivercan calmly react and is provided leeway for the next maneuver, resulting in safedriving conditions.Mazda Technical TrainingMX-5 Miata New Model TrainingSG-129
