Cruise Control Description & Operation: Notes

Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at vehicle speeds above 40 km/h (25 mph). Steep grades may cause variations in the selected vehicle speeds.

The following are the main components of the Cruise Control System:

• The accelerator pedal
• The powertrain control module (PCM)
• The on/off switch
• The resume/accel switch
• The set/coast switch
• The torque converter clutch (TCC)/brake switch
• The stop lamp switch
• The throttle actuator control (TAC) module
• The vehicle speed sensor (VSS)
