Traction Control
• The PCM calculates the target throttle valve opening angle by the torque up/down request signal from the DSC
HU/CM and TCM and the engine speed.
Cruise Control
• Calculates the throttle valve opening angle based on the deviation of the actual vehicle speed from the set
vehicle speed which was set with the cruise control switch and sends a duty signal to the throttle valve
actuator.
• The PCM controls the actual vehicle speed so that it is close to the set vehicle speed.
• The cruise control includes the cruise control operation condition and the cruise control stop condition.

— Cruise control related DTCs (P0564, P0571) detected
• When any of the following conditions are met even while in cruise control, the PCM stops the cruise control
while storing the set vehicle speed.
— Cancel switch: ON
— Neutral switch (MT) or CPP switch (MT): ON
— Inhibitor switch (AT) P/N position switch: ON
— Vehicle speed: Less than 22.5 km/h {13.9 mph}
— Brake switch: ON
— The actual vehicle speed is 15 km/h {9.3 mph} or more lower than the set vehicle speed during cruise
control (ascending).
— Condition where actual vehicle speed is 15 km/h {9.3 mph} or more lower than the set vehicle speed
