Function
|
---|
DSC HU/CM
|
• Makes calculations using input signals from each sensor, controls brake fluid pressure to each wheel, and actuates each function (ABS, EBD, TCS and DSC) of the DSC system.
• Outputs the torque reduction request signal, wheel speed signal and DSC system warning control data via CAN lines.
• Controls the on-board diagnostic system and fail-safe function when there is a malfunction in the DSC system.
|
PCM
|
• Controls engine output based on signals from the DSC HU/CM.
• Transmits engine speed, tire and shift position data via CAN communication to the DSC HU/CM.
• Transmits gear/selector lever position data via CAN communication to the DSC HU/CM.
|
DSC indicator light
|
• Informs the driver that the DSC is operating (vehicle sideslip occurring).
• Informs the driver that the TCS is operating (drive wheel is spinning).
• Informs the driver of DSC/TCS malfunction.
|
DSC OFF switch
|
• Transmits driver intention to release DSC control to the DSC HU/CM.
|
DSC OFF light
|
• Informs driver that DSC control has been released due to DSC OFF switch operation.
|
ABS wheel-speed sensor
|
• Detects the rotation condition of each wheel and transmits it to the DSC HU/CM.
|
Combined sensor
|
• Detects the lateral-G (vehicle speed increase) and the yaw rate (vehicle turning angle) of the vehicle and transmits them to the DSC HU/CM.
|
Brake fluid pressure sensor (Built into DSC HU/CM)
|
• Detects the fluid pressure from the master cylinder.
|
Steering angle sensor
|
• Detects the steering angle and transmits it to the DSC HU/CM.
