• The dynamic stability control (DSC)/roll stability control (RSC) system consists of the following parts. While
each part has a regular function in other systems, only the function during DSC/RSC control is listed.
End Of Sie
Part name Function
DSC/RSC HU/CM
• Makes calculations using input signals from each sensor, controls brake fluid pressure
to each wheel, and actuates each function (ABS, EBD, TCS, DSC and RSC) of the
DSC/RSC system.
• Outputs the torque reduction request signal, vehicle speed signal and DSC/RSC
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/RSC system.
PCM
• Controls engine output based on signals from the DSC/RSC HU/CM.
• Transmits engine speed, tire and shift position data via CAN communication to the
DSC/RSC HU/CM.
TCM
• Transmits gear/selector lever target position data via CAN communication to the DSC/
RSC HU/CM.
DSC indicator light
• Informs the driver that the RSC is operating.
• Informs the driver that the DSC is operating (vehicle sideslip occurring).
• Informs the driver that the TCS is operating (drive wheel is spinning).
TCS OFF switch • Transmits driver intention to release engine TCS control to the DSC/RSC HU/CM.
TCS OFF light
• Informs driver that engine TCS control has been released due to TCS OFF switch
operation.
ABS wheel-speed sensor • Detects the rotation condition of each wheel and transmits it to the DSC/RSC HU/CM.
Combined sensor
• Detects the lateral-G (vehicle speed increase), forward-G (vehicle speed increase),
yaw rate (vehicle turning angle) and roll rate (vehicle rolling angle) of the vehicle and
transmits them to the DSC/RSC HU/CM.
Brake fluid pressure sensor
(Builtinto DSC/RSC HU/CM)
• Detects the fluid pressure from the master cylinder and transmits it to the DSC/RSC
HU/CM.
BCM
• Transmits the steering angle and steering angle sensor condition via CAN lines to the
DSC/RSC HU/CM.
