Scan Tool Data Definitions Cruise Control

The Scan Tool Data Definitions contains a brief description of all cruise control related parameters available on the scan tool.

Battery Voltage Signal: The scan tool displays 6-18 Volts. The body control module (BCM) monitors the ignition voltage.

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

BPP Signal: The scan tool displays Applied, Released or Invalid.

CPP Switch: The scan tool displays Applied or Released.

Cruise Cancel Switch: The scan tool displays Active or Inactive. The status of the cruise cancel switch as monitored by the BCM.

Cruise Cancel Switch: The scan tool displays Active, Inactive or Invalid. The status of the cruise cancel switch as monitored by the ECM.

Cruise Control Active: The scan tool displays Active, Inactive or Invalid. The ECM determines the current status of the cruise control operation. An operating cruise control system is displayed as Active.

Cruise Control Switch: The scan tool displays Off/On/Error/Resume/Set. The body control module (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 the Scan Tool Data Definitions (Disengage History) for descriptions.

Cruise On/Off Switch: The scan tool displays On or Off. This is the state of the cruise control On/Off switch as detected by the ECM/PCM. An active switch is displayed as On.

Cruise Resume/Accel. Switch: The scan tool displays Active, Inactive, or Invalid. This is the state of the resume/accel switch as detected by the ECM. An active cruise resume/accel switch is displayed as Active.

Cruise Set/Coast Switch: The scan tool displays Active, Inactive, or Invalid. This is the state of the cruise set switch as detected by the ECM. An active cruise set switch is displayed as Active. The cruise control On/Off switch must be On in order to view the parameter correctly.

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.

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.
