Overview
The parking aid system sounds a warning to alert the driver of stationary objects near the rear bumper when REVERSE is selected. The rear sensors are activated when REVERSE is selected. The parking aid system assists the driver in detecting certain objects while the vehicle moves slowly in REVERSE at speeds of less than 4.8 kmh (3 mph). The parking aid system may not detect moving objects.
The parking aid system is active when the ignition switch is in the RUN position and the transmission in REVERSE. The parking aid system is disabled if a fault is detected in 1 of the 4 sensors, the parking aid speaker, or the PAM. This is indicated by a parking aid disabled warning message in the message center.
The parking aid system is enabled and disabled through the message center, located in the IPC.
If a MyKey® restricted key is in the ignition cylinder, the parking aid menu is not available in the message center and cannot be deactivated.
Scheme 2
The video camera system visually aids the driver while reversing or reverse parking the vehicle. The video camera system is controlled though the FDIM. Refer to the Owner's Literature for information on how to operate the video camera system features.

DTC FAULT TRIGGER CONDITIONS
REFER to Parking Aid System Operation .
The attenuation time for the rear parking aid sensors is the time required for a sensor to detect the distance to an object expressed in milliseconds (ms). A fault condition occurs when the signal or the attenuation time is out of normal range.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1B44:96 | Right Rear Outer Sensor: Component Internal Failure | A continuous and on-demand DTC that sets when the right rear outer parking aid sensor has internally failed or has an incorrect attenuation time. |
| B1B46:96 | Right Rear Inner Sensor: Component Internal Failure | A continuous and on-demand DTC that sets when the right rear inner parking aid sensor has internally failed or has an incorrect attenuation time. |
| B1B48:96 | Left Rear Outer Sensor: Component Internal Failure | A continuous and on-demand DTC that sets when the left rear outer parking aid sensor has internally failed or has an incorrect attenuation time. |
| B1B50:96 | Left Rear Inner Sensor: Component Internal Failure | A continuous and on-demand DTC that sets when the left rear inner parking aid sensor has internally failed or has an incorrect attenuation time. |
