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. On vehicles equipped with a 3.4L engine, a powertrain control module (PCM) is used. On vehicles equipped with a 3.6L engine, an engine control module (ECM) is used.

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

Cruise Control Active: The scan tool displays Yes or No. The PCM monitors the cruise engaged signal circuit. The cruise control module provides a ground on the cruise engaged signal circuit when the cruise control system is active. An active cruise control system is displayed as Yes.

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 (Disengaged History) for descriptions. Scan Tool Data Definitions - Disengage History

Cruise Inhibit Reason: The scan tool displays the reason that the cruise control is inhibited as detected by the ECM/PCM.

Cruise Inhibit Signal Circuit Status: The scan tool displays Ok or Fault. The PCM monitors the cruise inhibit circuit for a fault. A DTC is set when a fault is detected.

Cruise Inhibit Signal Command: The scan tool displays On or Off. On is displayed when the PCM commands the cruise control module to inhibit the cruise control system.

Cruise On/Off Switch: The scan tool displays On or Off. The ECM the monitors the cruise control on switch signal circuit. A closed switch is displayed as On.

Cruise Resume/Accel. Switch: The scan tool displays On or Off. The ECM the monitors the cruise control is resume/accel switch signal circuit. A closed switch is displayed as On.

Cruise Set/Coast Switch: The scan tool displays On or Off. The ECM the monitors the cruise control set/coast 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 Switch parameter.

Engine Speed: The scan tool displays 0 to 9,999 RPM. The ECM/PCM monitors the crankshaft position (CKP) signal circuit in order to determine the engine RPM.

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

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

Traction Control Status: The scan tool displays Active or Inactive. When the ECM receives a class 2 signal from the Electronic Brake Control Module (EBCM) requesting a traction control related function, the scan tool displays Active.

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