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 or 2.4L 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 (If Equipped)

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

Cruise Cancel Switch (2.4L)

- The scan tool displays Active, Invalid, or Inactive. This is the state of the cruise cancel switch as detected by the ECM. An active cruise cancel switch is displayed as Active. The cruise control On/Off switch must be On to view the parameter correctly.

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 Switch (2.2L)

- The scan tool displays On or Off. This is the state of the cruise set switch as detected by the ECM. An active cruise set 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 Active, Invalid, or Inactive. This is the state of the cruise set switch as detected by the ECM/PCM. An active cruise set switch is displayed as Active. 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.
