OUTLINE OF THE TCS (Traction Control System)

The traction control system controls excessive spinning (slipping) of the rear wheel when accelerat-
ing.
The ECU monitors the front and rear wheel speeds using the signals from the front and rear speed
sensors, and detects rear wheel slipping according to the difference between the wheel speeds. If
the slipping 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 six traction control system modes and an off mode.
