Scan Tool Data Definitions



SCAN TOOL DATA DEFINITIONS

The Scan Tool Data Definitions contains a brief description of all cruise control related parameters that are available on the scan tool. An engine control module (ECM) is used on a vehicle that is equipped with a 2.2 L (L61) engine and a powertrain control module (PCM) is used on a vehicle that is equipped with a 3.5 L (L66) engine.

Brake Switch: The scan tool displays Applied or Released. The ECM/PCM monitors the signal circuit of the stop lamp switch. An open switch is displayed as Released.

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

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

Cruise Brake Switch: The scan tool displays Applied or Released. The ECM/PCM monitors the signal circuit of the cruise/brake switch. An open switch is displayed as Applied.

Cruise Resume/Accel: The scan tool displays On or Off. The ECM/PCM monitors the signal circuit of the Resume/Accel. switch of the cruise control system. A closed switch is displayed as On. The cruise 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 ECM/PCM monitors the signal circuit of the Set/Coast switch of the cruise control system. A closed switch is displayed as On. The cruise 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 ECM/PCM monitors the CKP signal circuit in order to determine the engine RPM.

Ignition 1: The scan tool displays 6 to 18 Volts. The ECM/PCM monitors the Ignition 1 signal circuit in order to determine the system voltage.

Vehicle Speed: The scan tool displays 0 to 255 km/h (158 mph). The ECM/PCM monitors the vehicle speed sensor signal circuit in order to calculate the vehicle speed.
