Scan Tool Data Definitions

The Scan Tool Data Definitions contains a brief description of the Cruise Control System related parameters available on the scan tool.

ACC Gap Switch
- The scan tool displays Inactive/ Increase/ Decrease/ Error. The body control module (BCM) monitors the gap adjustment switch signal circuit. This is the state of the ACC gap switch as detected by the BCM.

Clean Radar Indicator Message
- The scan tool displays On / Off. This is the state of the clean radar indicator message as commanded by the distance sensing cruise control (DSCC) module.

Cruise Cancel Switch
- The scan tool displays Active/ Inactive/ Invalid. This is the state of the cruise cancel switch on/off switch as detected by the ECM.

Cruise Control Active
- The scan tool displays Yes / No. The ECM determines the current operational status of the cruise control system. An operating cruise control system is displayed as Yes.

Cruise Control Switch
- The scan tool displays Off / On / Invalid / Resume / Set. The instrument panel module (IPM) monitors the cruise control set/coast and accel/resume switch signal circuit in order to determine the status of the cruise control switch. The IPM sends a serial data message to the ECM indicating the status of the cruise control switch.

Cruise Disengage (1-8) History
- The scan tool displays the last 8 reasons why the ECM disengages the cruise control system. Refer to the Scan Tool Data Definitions (Disengage History - ECM) for the disengage reasons description. 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.

Cruise On / Off Switch Status
- The scan tool displays On / Off. This is the state of the cruise on / off switch as detected by the DSCC module.

Cruise Resume/Accel. Switch
- The scan tool displays Active/ Inactive/ Invalid. The ECM receives a GMLAN serial data message from the IPM indicating the status of the cruise control accel/resume switch. An active cruise control accel/resume switch is displayed as On.

Cruise Set/Coast Switch
- The scan tool displays Active/ Inactive/ Invalid. The ECM receives a GMLAN serial data message from the IPM indicating the status of the cruise control set/coast switch. An active cruise control set/coast switch is displayed as On. The cruise control On/Off switch must be On to view the Cruise Set/Coast Switch parameter correctly.

Driver Selected Speed
- The scan tool displays km/h (mph). This is the driver selected set speed as monitored by the ECM.

Driver Throttle Override Status
- The scan tool displays Active / Inactive. The ECM monitors the throttle and reports a throttle override condition initiated by the driver.

Engine Speed
- The scan tool displays 0-9999 RPM. This is the engine RPM as monitored by the ECM. The ECM monitors the CKP signal circuit in order to determine the engine RPM.

Follow Speed
- The scan tool displays km/h (mph). This is the following speed as determined by the DSCC module.

HUD Virtual Device
- The scan tool displays Present / Not Present. This is the state of the HUD as determined by the DSCC module.

Ignition 1 Signal
- The scan tool displays 6 volts to 18 volts. The ECM monitors the Ignition 1 signal circuit in order to determine the system voltage.

Service Radar Indicator Message
- The scan tool displays On / Off. This is the state of the service radar indicator as commanded by the DSCC module.

Target Found this Ignition Cycle
- The scan tool displays Yes / No. The FLS radar scans the road environment to detect the presence of a vehicle in its path. Yes is displayed if a target is acquired.

Vehicle Ahead Indicator Message
- The scan tool displays On / Off. This is the state of the vehicle ahead indicator as commanded by the DSCC module.

Vehicle Speed Sensor
- The scan tool displays 0-255 km/h (0 to 155 mph). The ECM monitors the vehicle speed sensor signal in order to calculate the vehicle speed for display.
