Cruise Control Module: Description and Operation
The cruise control module assembly is mounted on the right side of the engine compartment near the engine mount. The cruise control system uses the
cruise control module assembly in order to obtain the desired vehicle speed. Two important components in the module assembly help achieve the desired
vehicle speed; an electronic control module and an electric stepper motor. The control module uses a vehicle speed input from the PCM in order to
determine how to adjust the electric stepper motor. The motor moves a band and the throttle linkage in response to the control module in order to
maintain the desired cruise speed.
The cruise control module and the PCM have a low speed limit which will prevent the cruise control system from engaging below a speed of 25 mph (40
km/h). The PCM will not allow the cruise system to operate under certain conditions. When the cruise control system is enabled, the cruise control
module sends a signal to tell the PCM that cruise control module is controlling the vehicle speed. The cruise control module is not serviceable.
