Scan Tool Data Definitions (Cruise Control)

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

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

Cruise Control Active: The scan tool displays Yes or No. The ECM determines the current status of cruise control operation. An active cruise control system is displayed as Yes.
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 Inhibit Reason: The scan tool displays the reason whey the cruise control system is inhibited.
Cruise On/Off Switch: The scan tool displays On or Off. The engine control module (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 monitors the signal circuit of the cruise control switch. The scan tool displays On, when the cruise on/off switch is ON and the resume/accel (+) button is pressed, the ECM detects a predetermined voltage value for the resume/accel. switch.
Cruise Set/Coast Switch: The scan tool displays On or Off. The ECM monitors the signal circuit of the cruise control switch. The scan tool displays On, when the cruise on/off switch is ON and the ECM detects a predetermined voltage value for the set/coast (-) switch.
Engine Speed: The scan tool displays 0 to 9999 RPM. The ECM monitors the crankshaft position (CKP) signal circuit in order to determine the engine RPM.
Ignition 1 Signal: The scan tool displays Volts. This is the voltage at the ignition 1 input of the ECM.
Initial Brake Apply Signal: The scan tool displays Applied or Released. The electronic brake control module (EBCM) monitors the signal circuit of the brake pedal position sensor. When the ECM receives a class 2 message from the EBCM indicating that the brake pedal has been applied the scan tool displays Applied.
Stoplamp Pedal Switch: The scan tool displays Applied or Released. The ECM monitors the stop lamp switch signal circuit. When the brake pedal is pressed, the scan tool display Applied.
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 ECM monitors the vehicle speed sensor signal circuit in order to calculate the vehicle speed for display.
