Cruise Control Module

The cruise control system uses a cruise control module to obtain and hold any desired vehicle cruise speed above a minimum speed of 40 km/h (25 mph). Two components within the module help achieve this:
^ An electronic controller that monitors the following functions:
- Vehicle speed
- All cruise control system switch inputs
- Cruise control release
- Stop lamp switch inputs
- Operates the electric stepper motor
^ A stepper motor which moves an internal strap (linked to the throttle lever via the cruise control cable) in response to the controller to maintain the desired cruise speed.
