Cruise Control Module: Description and Operation

The cruise control module assembly is mounted on the engine compartment cowl. The cruise control module assembly allows the cruise control system to obtain the desired vehicle speed. The cruise control module assembly consists of an electronic control module and an electric stepper motor. The control module uses a vehicle speed input from the PCM to determine how to adjust the electric stepper motor. The stepper 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 prevents 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 signals the PCM to let the PCM know that the cruise control module is controlling the vehicle speed. The cruise control module is not serviceable.
