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 available on the scan tool. On vehicles equipped with a 2.0L engine, a powertrain control module (PCM) is used. On vehicles equipped with a 2.2L engine, an engine control module (ECM) is used.

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

Clutch Pedal Switch
- The scan tool displays Applied or Released. The PCM monitors the clutch pedal position (CPP) switch signal circuit. An open switch is displayed as Applied.

CPP Switch
- The scan tool displays Applied or Released. The ECM monitors the clutch pedal position (CPP) switch signal circuit. An open switch is displayed as Applied.

Cruise Control Active
- The scan tool displays Yes or No. The ECM/PCM 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 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. The listed values are voltage values from a known good cruise control switch. Off = 0.0 Volts / On = 0.6 Volts / Resume = 1.5 Volts / Set = 3.0 Volts.

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. Scan Tool Data Definitions (Disengage History)

Cruise On/Off Switch
- The scan tool displays On/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 On or Off. This is the state of the resume/accel switch as detected by the ECM/PCM. An active cruise resume and accel switch is displayed as On. The cruise control On/Off switch must be On to view the parameter correctly.

Cruise Set/Coast Switch
- The scan tool displays On or Off. This is the state of the cruise set switch as detected by the ECM/PCM. An active cruise set switch is displayed as On. The cruise control On/Off switch must be On 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/PCM. The ECM/PCM 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/PCM monitors the voltage of the ignition 1 voltage circuit.

Initial Brake Apply Signal
- The scan tool displays Applied or Released. The PCM monitors the cruise/brake switch signal circuit. An open switch is displayed as Applied.

Reduced Engine Power
- The scan tool displays Active or Inactive. When the ECM/PCM detects that a reduced engine power condition exists, the scan tool displays Active.

Stop Lamp Pedal Switch
- The scan tool displays Applied or Released. The ECM/PCM monitors the stop lamp pedal switch signal circuit. An activated brake pedal is displayed as Applied.

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

Traction Control Status
- The scan tool displays Active or Inactive. When the ECM/PCM 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/PCM monitors the vehicle speed sensor signal in order to calculate the vehicle speed for display.
