TCS (Traction control system) block diagram
The signals from the front and rear wheel sensors are sent to the ECU through the ABS ECU, and the
ECU calculates the amount of slip according to the difference between the detected front and rear
wheel speeds.
If the amount of slip exceeds the preset value, the ECU controls the ignition timing, fuel cut-off, and
throttle valve opening of the YCC-T system so that the amount of slip is less than the preset value. The
traction control system indicator/warning light in the multi-function meter center display flashes when
the traction control system has activated.
