System Operation
Cruise Control - Non Adaptive
Component Description
Steering Wheel Switches
The cruise control steering wheel mounted switches are momentary contact switches. Each steering wheel switch function corresponds to a specific resistance value. The SASM (Steering Angle Sensor Module) sends out a 5 volt reference voltage to the steering wheel switch and monitors the voltage when a switch is pressed. The voltage varies depending upon the resistance of the specific switch pressed, indicating which switch is pressed.
Brake Switch
When the brake pedal is applied, an electrical signal from the stoplamp circuit to the PCM (Powertrain Control Module) deactivates the system. Under increased brake pedal effort, the cruise control deactivator switch opens and removes the ground signal from the PCM (Powertrain Control Module) input circuit, releasing the throttle immediately deactivating the system.
Clutch Switch
Vehicles equipped with a manual transmission have an additional clutch pedal cruise control deactivator switch. The clutch pedal cruise control deactivator switch is a normally open switch with the clutch pedal released. When the clutch pedal is pressed, an electrical signal from the clutch pedal speed control deactivator switch circuit PCM (Powertrain Control Module) deactivates the system.
