SCAN TOOL DATA DEFINITIONS

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 powertrain control module (PCM) determines the current status of cruise control operation. An active cruise control system is displayed as Yes.

Cruise Enabled: The scan tool displays Yes or No. This parameter is for the cruise control On/Off switch. The PCM monitors the cruise control set/coast and resume/accelerate switch signal circuit. A closed switch is displayed as Yes.

TCC Release Switch: The scan tool displays open or closed. The PCM monitors the signal circuit of the torque converter clutch (TCC)/cruise control release switch. A closed switch is displayed as closed.

Cruise Resume/Accel: 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 parameter.

Cruise Set/Coast: 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 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 Volts to 18 Volts. The PCM monitors the Ignition 1 signal circuit in order to determine the system voltage.

Reduced Engine Power: The scan tool displays Active or Inactive. When the PCM detects that an overheated engine condition exists, the scan tool displays Active.

Stoplamp Pedal Switch: The scan tool displays Applied or Released. The PCM monitors the stop lamp switch signal circuit. A closed switch is displayed as Applied.

Vehicle Speed Sensor: The scan tool displays 0 to 150 km/h (0 to 93.2 mph). The PCM monitors the vehicle speed sensor signal circuit in order to calculate the vehicle speed for display.
