Scan Tool Data Definitions (Cruise Control)

WARNING: This page is about a different car, the 2004 Cadillac SRX. 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.

Cruise Control Active: The scan tool displays Yes or No. The engine control module (ECM) determines the current status of cruise control operation. An active cruise control system is displayed as Yes.
Cruise Control Switch: The scan tool displays On, Off, Set, Resume, or Error. The ECM monitors the signal circuit of the cruise control switch.
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 Inhibited: The scan tool displays Yes or No. The ECM determines when the conditions for inhibiting the cruise control system exists. An inhibited cruise control system is displayed as Yes.
Cruise Inhibit Reason: The scan tool displays the reason that the cruise control is inhibited as detected by the ECM.
Cruise Inhibit Signal Command: The scan tool displays On or Off. The ECM determines when the conditions for inhibiting the cruise control system exists. An inhibited cruise control system is displayed as On.
Cruise On/Off Switch: The scan tool displays On or Off. The ECM monitors the signal circuit of the cruise control switch. A closed switch is displayed as On.
Cruise Resume/Accel. Switch: The scan tool displays On or Off. The ECM the monitors the cruise control set/coast and resume accel 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 Set/Coast Switch: The scan tool displays On or Off. The ECM the monitors the cruise control set/coast and resume accel 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.
Engine Speed: The scan tool displays 0 to 9,999 RPM. The ECM monitors the crankshaft position (CKP) signal circuit in order to determine the engine RPM.
Initial Brake Apply Signal: The scan tool displays Applied or Released. The EBCM monitors the signal circuit of the brake pedal position sensor. When the ECM receives a class 2 serial data message from the EBCM indicating that the brake pedal has been applied, the scan tool displays Applied.
Reduced Engine Power: The scan tool displays Active or Inactive. When the ECM determines that a throttle actuator control system malfunction exists, the scan tool displays Active.
Stoplamp Pedal Switch: The scan tool displays Applied or Released. The ECM monitors the stop lamp switch signal circuit. An open switch is displayed as Applied.
Traction Control Status: The scan tool displays Active or Inactive. When the ECM receives a class 2 signal from the Electronic Brake Control Module (EBCM) requesting a traction control related function, the scan tool displays Active.
Vehicle Speed Sensor: The scan tool displays 0 to 150 km/h (93.2 mph). The ECM monitors the vehicle speed sensor signal circuit in order to calculate the vehicle speed for display.
