Cruise Control

The cruise control system on this vehicle is different from conventional systems in that there is no cable to hold the throttle open, nor is there a cruise control module. The electronic throttle control system makes these components unnecessary, and simplifies cruise control diagnostics. This is because a cruise control failure means that one or more of the sensors or switches associated with the system are not working properly. Diagnosing and correcting these sensor and switch failures will also restore the cruise control system to its proper functioning state.

The following diagnostic trouble codes DTCs could result in cruise control malfunctions, and should be diagnosed in the case of a cruise control inoperative condition.

Cruise control operation is prohibited by the engine control module (ECM) if it detects an invalid signal from the vehicle speed sensor, from the cruise/brake or stop lamp switches. Cruise control will remain inoperable until the end of the ignition cycle even if the fault condition should disappear.
