Scan Tool Data Definitions (Cruise Control)

WARNING: This page is about a different car, the 2007 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

The Scan Tool Data Definitions contains a brief description of all cruise control related parameters available on the scan tool.

On vehicles equipped with a 3.8L engine, a powertrain control module (PCM) is used. On vehicles equipped with a 5.3L engine, and engine control module (ECM) is used.

Cruise Cancel Switch: The scan tool displays Active, Inactive or Invalid. The ECM determines the current status of cruise cancel switch. An active cruise cancel switch is displayed as Active.
Cruise Control Active (3.8L): The scan tool displays Yes or No. The PCM determines the current status of cruise control operation. An active cruise control system is displayed as Yes.
Cruise Control Active (5.3L): The scan tool displays Active, Inactive or Invalid. The ECM determines the current status of cruise control operation. An active cruise control system is displayed as Active.
Cruise Disengage (1-8) History: The scan tool displays the last 8 reasons why the cruise control system was disengaged. Refer to the Scan Tool Data Definitions (Disengaged History) for descriptions.
Cruise On/Off Switch: The scan tool displays On or Off. The ECM/PCM monitors the cruise control set/coast and resume/accelerate switch signal circuit. A closed switch is displayed as On.
Cruise Resume/Accel. Switch: The scan tool displays On or Off. The PCM monitors the cruise control set/coast and resume/accelerate switch signal circuit. A closed switch is displayed as On. The cruise control On/Off switch must be switched On in order to correctly view the Cruise Resume/Accel. Switch parameter.
Cruise Resume/Accel. Switch: The scan tool displays Active, Inactive or Invalid. The ECM monitors the cruise control set/coast and resume/accelerate switch signal circuit. A closed switch is displayed as Active. The cruise control On/Off switch must be switched On in order to correctly view the Cruise Resume/Accel. Switch parameter.
Cruise Set/Coast Switch: The scan tool displays On or Off. The PCM monitors the cruise control set/coast and resume/accelerate switch signal circuit. A closed switch is displayed as On. The cruise control On/Off switch must be switched On in order to correctly view the Cruise Set/Coast Switch parameter.
Cruise Set/Coast Switch: The scan tool displays Active, Inactive or Invalid. The ECM monitors the cruise control set/coast and resume/accelerate switch signal circuit. A closed switch is displayed as Active. The cruise control On/Off switch must be switched On in order to correctly view the Cruise Set/Coast Switch parameter.
Engine Run Time: Scan tool range 00:00:00-99:99:99 Hrs:Min:Sec. Indicates the time elapsed since the engine was started. If the engine is stopped, ENGINE RUN TIME will be reset to 00:00:00.
Engine Speed: The scan tool displays 0 to 9,999 RPM. The PCM/ECM monitors the CKP signal circuit in order to determine the engine RPM.
Ignition 1 Signal: The scan tool displays 6 Volts to 18 Volts. The PCM/ECM monitors the ignition 1 signal circuit in order to determine the system voltage.
Stoplamp Pedal Switch: The scan tool displays Applied or Released. The PCM monitors the stoplamp pedal switch circuit. When the PCM detects voltage on the stop lamp switch signal circuit, the scan tool displays Applied.
Stoplamp Pedal Switch Signal: The scan tool displays Volts. The PCM monitors the stoplamp pedal switch signal circuit in order to determine the voltage.
Traction Control Status: The scan tool displays Active or Inactive. When the ECM detects that the traction control is active, the scan tool displays Active.
Vehicle Speed Sensor: The scan tool displays 0 to 150 km/h (93.2 mph). The PCM/ECM monitors the vehicle speed sensor signal circuit in order to calculate the vehicle speed for display.
