Outline<\/p>\n

\u2022 The TCS control actuates torque reduction through engine control, as well as using brake control to control traction.<\/div>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\n
\u2022 Engine control: Engine output is lowered by fuel cut and ignition timing control to reduce the traction, preventing driving wheel slip.<\/div>\n
\u2022 Brake control: Brake fluid pressure from the hydraulic unit (HU) to the driving wheel that is slipping is increased, operating the brake and preventing driving wheel slip.<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n

Features<\/p>\n

\u2022 The left and right wheels are controlled at the same time by engine control. Therefore, when the road surface friction coefficients differ between the left and right wheels, proper torque reduction cannot be performed separately for each wheel. When this occurs, torque reduction is performed by independent left and right wheel brake control, providing more stable vehicle control.<\/div>\n
\u2022 The DSC OFF switch allows the driver to optionally enable\/disable the TCS control at the driver’s discretion.<\/div>\n
\n
\n
\u2015 When both driving wheels are stuck, traction control according to the driver’s operation can be performed by inhibiting the TCS control.<\/div>\n
\u2015 The TCS control returns to normal operation automatically at the next ignition cycle.<\/div>\n<\/dd>\n<\/dl>\n

Operation<\/p>\n

\u2022 TCS control detects driving wheel spin based on the signals listed below, sends torque reduction request signals to the PCM, and also controls the solenoid valves and pump motor in the DSC HU\/CM.<\/div>\n
\n
\n
\u2015 Vehicle wheel speed signals from the front and rear ABS wheel-speed sensors<\/div>\n
\u2015 Engine torque signal from the PCM<\/div>\n
\u2015 Steering angle signal from the EPS CM<\/div>\n
\u2015 Yaw rate and lateral-G signals from the SAS control module<\/div>\n
\u2015 Fluid pressure signal from the brake fluid pressure sensor (built into the DSC HU\/CM)<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
