04 BRAKESDynamic Stability ControlDSC Construction• The DSC system consists of the following parts. While each part has a regularfunction in other systems, only the function during DSC control is listed.Part nameFunction• Makes calculations using input signals from eachsensor, controls brake fl uid pressure to each wheel, andactuates each function (ABS, EBD, TCS and DSC) ofthe DSC system.DSC HU/CM• Outputs the torque reduction request signal, vehiclespeed signal and DSC system warning control data viaCAN lines.PCMTCM (AT)DSC indicator lightDSC OFF switchDSC OFF lightWheel speed sensorCombined sensorBrake fl uid pressuresensorSteering angle sensorMazda Technical TrainingMX-5 Miata New Model Training• Controls the on-board diagnostic system and failsafefunction when there is a malfunction in the DSCsystem.• Controls engine output based on signals from the DSCHU/CM.• Transmits engine speed, tire and shift position data viaCAN communication to the DSC HU/CM.• Transmits gear/selector lever target position data viaCAN communication to the DSC HU/CM.• Informs the driver that the DSC is operating (vehiclesideslip occurring).• Informs the driver that the TCS is operating (drive wheelis spinning).• Transmits driver intention to release DSC control to theDSC HU/CM.• Informs driver that DSC control has been released dueto DSC OFF switch operation.• Detects the rotation condition of each wheel andtransmits it to the DSC HU/CM.• Detects the lateral-G (vehicle speed increase) andthe yaw rate (vehicle turning angle) of the vehicle andtransmits them to the DSC HU/CM.• Detects the fl uid pressure from the master cylinder andtransmits it to the DSC HU/CM.• Transmits the steering angle and steering angle sensorcondition via CAN lines to the DSC HU/CM.SG-135
