Cruise Control: Scan Tool Testing and Procedures
Scan Tool Data Definitions (Cruise Control)
Scan Tool Data Definitions (Cruise Control)
The Scan Tool Data Definitions contains a brief description of all cruise control related parameters that are available on the scan tool. Vehicles equipped
with a 4.2L (LL8) engine use a powertrain control module (PCM). Vehicles equipped with a 5.3L (LH6) engine use an engine control module (ECM).
Cruise Control Active
-
The scan tool displays Yes or No. The PCM determines the current status of cruise control operation. An active cruise control system is displayed
as Yes.
Cruise Control Active
-
The scan tool displays Active or Inactive. The ECM determines the current status of the Cruise Control System. An active Cruise Control System
is displayed as Active.
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. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Scan Tool Testing and
Procedures/Scan Tool Data Definitions
Cruise On/Off Switch
-
The scan tool displays On or Off. The PCM monitors the signal circuit of the On/Off switch of the cruise control system. A closed switch is
displayed as On.
Cruise On/Off Switch
-
The scan tool displays Active or Inactive. The ECM monitors the signal circuit of the Cruise Control System On/Off switch. A closed switch is
displayed as Active.
Cruise Release Clutch/TCC Pedal Switches
-
The scan tool displays Applied or Released. The PCM monitors the TCC brake switch/Cruise control release signal circuit. An open switch is
displayed as Applied.
Cruise Resume/Accel. Switch
-
The scan tool displays On or Off. The PCM monitors the signal circuit of the Resume/Accel. switch of the cruise control system. A closed switch
is displayed as On.
Cruise Resume/Accel. Switch
-
The scan tool displays Active or Inactive. The ECM monitors the signal circuit of the Resume/Accel. switch of the Cruise Control System. A
closed switch is displayed as Active.
Cruise Set/Coast Switch
-
The scan tool displays On or Off. The 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 Switch parameter.
Cruise Set/Coast Switch
-
The scan tool displays Active or Inactive. The ECM monitors the signal circuit of the Set/Coast switch of the Cruise Control System. A closed
switch is displayed as Active. The cruise 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 CKP signal circuit in order to determine the engine RPM.
