System Operation

OPERATION
- The cruise control automatically controls vehicle speed and allows the vehicle to run at a constant speed without depressing the accelerator pedal.
- The cruise control module compares the actual vehicle speed detected by feedback signals from the speed sensor 2 (MT) or TCM (AT) with the speed set in the memory memorized when the set switch was turned on.

A signal is then transmitted according to the difference between the two speeds. This signal is transmitted to the solenoid valve in the vacuum actuator located at the engine compartment.

The movement of the actuator operates the throttle cam, thereby keeping the vehicle speed constant.
