TCS CONTROL OPERATION

id041800819000

• Traction control system (TCS) control detects a slipping drive wheel using the following signals, sends a torque reduction request signal to the PCM and, at the same time, controls the solenoid valves and pump motor in the dynamic stability control (DSC)/roll stability control (RSC) hydraulic unit (HU)/control module (CM).

  ― Vehicle wheel speed signals from the front and rear ABS wheel-speed sensors
  ― Engine torque signal from the PCM
  ― Steering angle signal from the body control module (BCM)
  ― Yaw rate, roll rate, forward-G and lateral-G signals from the SAS control module
  ― Fluid pressure signals from the brake fluid pressure sensors
