TCS CONTROL OPERATION

BHE041543750T08

• 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 DSC HU/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 steering angle sensor
  – Yaw rate and lateral-G signals from the combined
  – Fluid pressure signals from the brake fluid pressure sensors
