6. ETCS-i (Electronic Throttle Control System-intelligent)
General
D In the conventional throttle body, the throttle valve angle is determined invariably by the amount of the
accelerator pedal effort. In contrast, ETCS-i uses the THS ECU to calculate the optimal throttle valve
angle that is appropriate for the respective driving condition and uses a throttle control motor to control
the angle.
D In case of an abnormal condition, this system transfers to the limp mode.
