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, fuel cut-off, and throttle valve opening of the YCC-T system.
The traction control system can be set to one of two operation modes or turned off.
