Scan Tool Data Definitions

SCAN TOOL DATA DEFINITIONS (CRUISE CONTROL)

BPP Circuit Signal: The scan tool displays Applied or Released. The engine control module (ECM) monitors the stop lamp pedal switch signal circuit. An activated brake pedal is displayed as Applied.

BPP Signal: The scan tool displays Applied/Released/Invalid. The body control module (BCM) monitors the signal circuit of the brake pedal position sensor. When the ECM receives a GMLAN serial data message from the BCM indicating that the brake pedal has been applied, the scan tool displays Applied.

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

Cruise Control Active: The scan tool displays Yes or No. The ECM determines the current status of the cruise control operation. An operating Cruise Control System is displayed as Yes.

Cruise Control Switch: The scan tool displays Off/On/Error/Resume/Set. The BCM monitors the cruise control set/coast and resume/accel switch signal circuit in order to determine the status of the cruise control switch.

Cruise Control Switch: The scan tool displays 0-5 volts. The BCM monitors the voltage of the cruise control set/coast and resume/accel switch signal circuit. in order to determine the status of the cruise control switch.

Cruise Control Switch Sw. to Batt. Voltage Ratio: The scan tool displays percent (%). This is the ratio of the cruise control switch voltage to battery voltage.

Cruise Disengage (1-8) History: The scan tool displays the last 8 reasons why the Cruise Control System was disengaged. Refer to Scan Tool Data Definitions (Cruise Control) Scan Tool Data Definitions (Disengage History), Disengage History for descriptions. Scan Tool Data Definitions (Disengage History)

Engine Speed: The scan tool displays 0 to 9999 RPM. This is the engine RPM as monitored by the ECM. The ECM monitors the crankshaft position (CKP) signal circuit in order to determine the engine RPM.

Ignition 1 Signal: The scan tool displays 0 to 25.5 volts. The ECM monitors the voltage of the ignition 1 voltage circuit.

Reduced Engine Power: The scan tool displays Active or Inactive. When the ECM detects that a reduced engine power condition exists, the scan tool displays Active.

Traction Control Status: The scan tool displays Active or Inactive. When the ECM detects that a traction control condition exists, the scan tool displays Active.

Vehicle Speed Sensor: The scan tool displays 0-255 km/h (0-155 mph). The ECM monitors the vehicle speed sensor signal in order to calculate the vehicle speed for display.
