WARNING: This page is about a different car, the 2006 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.

The scan tool data definitions contain a brief description of all object detection system related parameters available on the scan tool. The parameters that are available on the scan tool are listed below in alphabetical order.

Battery Voltage: The scan tool displays 0 -19 volts. This is the system battery voltage as detected by the object alarm module.
Loudspeaker Feed Voltage Output: The scan tool displays voltage/counts. This is the radio loudspeaker feed voltage/counts output as monitored by the object alarm module.
Park Assist Disable History (1 - 8): The scan tool displays Empty/Manual Disable/Park Brake/Hitch Object Attached/Reverse Overspeed/Inhibit/Sensor Disturbance/Snow,Ice,Mud/Sensor Ring Time. The object alarm module maintains 8 history data for the park assist system at all times. This data represents the last 8 reasons why the park assist system was disabled.
Park Assist Switch: The scan tool displays Active/Inactive. This is the state of the park assist switch as detected by the object alarm module.
Park Assist Switch LED: The scan tool displays Off/On. This is the state of the park assist switch LED.
Park Assist Switch LED CKT: The scan tool displays Ok/Over Current. This is the status of the park assist switch LED circuit as monitored by the object alarm module.
Park Assist Front Display LED CKT: The scan tool displays Ok/Overcurrent. This is the status of the park assist front display LED circuit as monitored by the object alarm module.
Park Assist Front Y1 LED: The scan tool displays Off/On. This is the state of the park assist front Y1 LED as detected by the object alarm module.
Park Assist Front Y2 LED: The scan tool displays Off/On. This is the state of the park assist front Y2 LED as detected by the object alarm module.
Park Assist Front Red LED: The scan tool displays Off/On. This is the state of the park assist front red LED as detected by the object alarm module.
Park Assist Rear Display LED CKT: The scan tool displays Ok/Overcurrent. This is the status of the park assist rear display LED circuit as monitored by the object alarm module.
Park Assist Rear Y1 LED: The scan tool displays Off/On. This is the state of the park assist rear Y1 LED as detected by the object alarm module.
Park Assist Rear Y2 LED: The scan tool displays Off/On. This is the state of the park assist rear Y2 LED as detected by the object alarm module.
Park Assist Rear Red LED: The scan tool displays Off/On. This is the state of the park assist rear red LED as detected by the object alarm module.
Park Assist System Status: The scan tool displays Enable/Disable/Inhibit/Failed/Blocked. This is the status of the park assist system as monitored by the object alarm module.
Power Mode: The scan tool displays Off/Accessory/Run/Crank Request. This is the status of the vehicle power mode as detected by the object alarm module.
Rear Region (1 - 4): The rear object detection system field of view is divided into 4 regions as displayed in the scan tool. The scan tool displays No Detect/Zone 1/Zone 2/Zone 3/Zone 4/Zone 5/Zone 6/Zone 7/Zone 8 for each of the 4 regions. The object alarm module translates the object of interest distance data into specific range zones.
Sensor Feed Voltage Output: The scan tool displays voltage/counts. This is the object sensor feed voltage/counts output as monitored by the object alarm module.
Vehicle Speed: The scan tool displays mph (km/h). This is the vehicle speed as detected by the object alarm module. The object alarm module receives vehicle speed information from the ECM.
