Cruise Control System Description - Overview
The cruise control system maintains a constant vehicle speed without operating the accelerator pedal.
Operation
To operate the cruise control system, the driver must first turn on the CRUISE/MAIN switch. With the CRUISE/MAIN switch on, the
cruise main indicator appears in the gauge control module, and the gauge control module will send cruise control commands to the
PCM via the F-CAN line.
The speed value is set at the moment the driver releases the SET button on the combination switch. Once the speed is set, the cruise
control system maintains this speed in the system memory until: A new speed replaces the current value, the CRUISE/MAIN switch is
turned off, the brake pedal is depressed, the clutch pedal (M/T) is depressed for more than five seconds, or the CANCEL button is
pressed.
The driver can also increase and decrease the set speed by pressing the plus () and minus () buttons on the combination switch.
To maintain the set speed, the PCM monitors the throttle actuator position using the throttle position sensor and controls the speed by
commanding the throttle actuator to open and close as needed.
The system changes its cruise control throttle inputs depending on whether the vehicle's ECON mode is on or off.
When the ECON mode is on, the system limits the throttle position to prevent excessive throttle application to improve fuel economy
when there is a change in vehicle load - for example, it will take longer for the vehicle to accelerate to the set speed or applyin
g
throttle to maintain speed when climbing a hill. When the ECON mode is off, the vehicle will accelerate quicker to compensate for the
change in vehicle load.
