04 BRAKESDynamic Stability ControlDSC HU Part Construction/Operation (continued)During ABS and EBD control• During ABS and EBD control, when wheel lock-up is about to occur, the tractioncontrol solenoid valve and stability control solenoid valves are not energized, andthe inlet and outlet solenoid valves are energized and controlled in three pressuremodes (increase, reduction or maintain), thereby adjusting brake fl uid pressure.Brake fl uid during pressure reduction is temporarily stored in the reservoir andafterwards the pump motor operates the pump to return the fl uid to the mastercylinder. (The following fi gure shows these conditions: right front wheel pressureincreased, left front wheel pressure maintained, and both rear wheels pressuredecreased.)Solenoid valve operation table• Refer to Service Highlights, page 04-15-8 to view the table.Hydraulic circuit diagram(continued)Mazda Technical TrainingMX-5 Miata New Model TrainingSG-139
