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.

Battery Voltage: The scan tool displays the battery voltage. The ECM monitors the battery positive voltage circuit.

Clutch Pedal Switch: The scan tool displays Applied or Released. The ECM monitors the signal circuit of the Clutch Pedal Position (CPP) switch. A closed switch is displayed as Released.

Cruise Engaged: The scan tool displays Yes or No. When the ECM detects that the cruise control system has been requested, and the cruise engagement criteria has been met, the cruise control activates and the scan tool displays Yes.

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 Release Brake Pedal Switch: The scan tool displays Applied or Released. The ECM monitors the TCC brake switch/cruise control release signal circuit. A closed switch is displayed as Released.

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 cruise 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.

Cruise -- VSS Out of Range: The scan tool displays Yes or No. The ECM monitors the signal circuit of the vehicle speed signal sensor. When the ECM detects that the vehicle speed is below 40.2 km/h (25 mph), the scan tool displays Yes.

Extended Travel Brake Pedal Switch: The scan tool displays Applied or Released. The ECM monitors the signal circuit of the extended travel brake pedal switch. A closed switch is displayed as Released.

Vehicle Speed: The scan tool displays km/h or mph. The ECM monitors the signal circuit of the vehicle speed signal sensor.
