Cruise Control Description and Operation: Notes

Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at 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 brake pedal position (BPP) sensor
• The body control module (BCM)
• The cruise control cancel switch
• The cruise on/off switch
• The + RES switch (equivalent to resume/accel switch)
• The - SET switch (equivalent to set/coast switch)
• The engine control module (ECM)
• The throttle actuator control (TAC) motor
• The vehicle speed sensor
