Cruise Control Description and Operation (3.5L): 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 On/Off switch
• The engine control module (ECM)
• The + RES switch

  The + RES switch is the equivalent to an accel/resume switch.

• The - SET switch

  The - SET switch is the equivalent to a set/coast switch.

• The throttle actuator control (TAC) module
• The TAC motor
• The vehicle speed sensor
