Cruise Control Module: Description and Operation

Speed Control Actuator
The speed control actuator is mounted on the right-hand inner fender behind the suspension unit top mount. The speed control actuator incorporates the following components:
- The electronic speed control unit
- The stepper motor and geartrain, electromagnetic coupling and reduction gearing

Speed Control Unit
The speed control unit evaluates incoming signals from the system sensors and switches. It actuates a stepper motor and cable linkage to adjust the throttle body cam, maintaining a constant vehicle road speed.

If the vehicles brake or the clutch pedal are depressed, the speed control unit interrupts the speed control operation.

Stepper Motor
When the speed control system is activated, the windings in the stepper motor are energized by the speed control unit ensuring accurate positioning of the throttle body cam. The vehicle road speed then settles to the speed selected by the driver.
