Cruise Control: Operation

• The cruise control system automatically controls the vehicle speed. It allows the vehicle to run at a constant speed without need for the driver to keep the accelerator pedal depressed.
• On non-turbo models, when the driver has activated the system and made a desired speed setting, the cruise control module compares the actual vehicle speed detected by the speed sensor (MT) or transmission control module (AT) with the preset speed in the memory, then generates a signal according to the difference between the two speeds.

  This signal is transmitted to the actuator located in the engine compartment.

  The actuator operates the throttle cam as necessary to keep the preset vehicle speed.

• On turbo models, when the driver has activated the system and made a desired speed setting, the engine control module (ECM) compares the actual vehicle speed detected by the speed sensor (MT) or by the transmission control module (AT) with the preset speed in the engine control module (ECM) memory, and then generates a signal according to the difference between the two speeds. This signal is transmitted to the electronic control throttle.

The electronic control throttle operates the throttle valve as necessary to keep the preset vehicle speed.
