Scan Tool Data Definitions - Cruise Control

SCAN TOOL DATA DEFINITIONS (CRUISE CONTROL)

Battery Voltage Signal: The scan tool displays 6-18 volts. The engine control module (ECM) monitors the ignition voltage.

BPP Circuit Signal: The scan tool displays Applied or Released. The 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 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.
