OUTLINE OF THE TCS (Traction Control System)

The traction control system controls excessive spinning (slipping) of the rear wheel when accelerating

on slippery surfaces, such as unpaved or wet roads.

The ECU monitors the front and rear wheel speeds using the signals from the front and rear wheel sen-

sors, and detects rear wheel slipping according to the difference between the wheel speeds. If the slip-

ping exceeds the preset value, the ECU controls the slipping using integrated control of the ignition

timing and fuel cut-off.

The traction control system can be set to “ON” operation modes or turned “OFF”.

FEATURES

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 and fuel cut-off so

that the amount of slip is less than the preset value. The traction control system indicator light in the

meter assembly flashes when the traction control system has activated.
