Scan Tool Data Definitions (Cruise Control)

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. 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 that are available on the scan tool.

Cruise Control Active: 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 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 PCM monitors the signal circuit of the On/Off switch of the cruise control system. A closed switch is displayed as On.
Cruise Release Brake Pedal Switch: The scan tool displays Applied or Released. The PCM monitors the TCC brake switch/Cruise control release signal circuit. An open switch is displayed as Applied.
Cruise Release Clutch/TCC Pedal Switches: The scan tool displays Applied or Released. The PCM monitors the TCC brake switch/Cruise control release signal circuit. An open switch is displayed as Applied.
Cruise Resume/Accel. Switch: The scan tool displays On or Off. The PCM monitors the signal circuit of the Resume/Accel. switch of the cruise control system. A closed switch is displayed as On.
Cruise Set/Coast Switch: The scan tool displays On or Off. The PCM monitors the signal circuit of the Set/Coast switch of the cruise control system. A closed switch is displayed as On. The cruise 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 PCM monitors the CKP signal circuit in order to determine the engine RPM.
Ignition 1 Signal: The scan tool displays 6 to 18 Volts. The PCM 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 signal circuit of the stop lamp switch. An open switch is displayed as Released.
TAC/PCM Communication Signal: The scan tool displays OK or Fault. The PCM uses the UART serial data circuit in order to communicate with the TAC module. If the communication between the PCM and the TAC motor is interrupted, the scan tool displays Fault.
Vehicle Speed Sensor: The scan tool displays 0 to 255 km/h (158 mph). The PCM monitors the vehicle speed sensor signal circuit in order to calculate the vehicle speed for display.
