NOTE: The liftgate must be fully closed for correct operation of the rear parking aid camera system.

The rear parking aid camera image is displayed by the FDIM when the transmission is placed in reverse. To determine the selector lever position and enable the rear parking aid camera display, the PCM sends the gear position message to BCM and the APIM the on the HS-CAN1. The rear parking aid camera generates a video signal any time it receives voltage, regardless of the current configuration. If the rear parking aid camera is not configured properly, some features may be inoperative. The rear parking aid camera is supplied voltage when the ignition is on. When the rear parking aid camera is on, the image signal is sent from the rear parking aid camera on shielded twisted pair wires to the APIM, which displays the image on the FDIM.

The following rear parking aid camera system features are driver selectable:

Visual park aid alert -- assists the driver to visually see the object causing the parking aid system to sound.
Manual zoom -- allows the driver to manually zoom closer to an object behind the vehicle.
Video delay -- allows the driver to see the image behind the vehicle after the vehicle is shifted out of reverse. The image is not displayed if the vehicle is shifted into park.

The following rear parking aid camera system features are not driver selectable:

Fixed guidelines -- assists the driver with backing into a parking space or aligning the vehicle with an object.
Active guidelines -- projects the intended path of the vehicle based on steering wheel input.

The FDIM settings menu is used to turn the visual park aid alert and video delay on and off. The visual park aid alert and video delay features are generated and controlled by the APIM.

To turn the manual zoom feature on and off, the driver uses an on screen button located on the FDIM while in reverse. The driver generated commands originate at the FDIM, which is hardwired to the APIM. The APIM sends the driver generated commands to the BCM on the HS-CAN1. The BCM sends the command to the rear parking aid camera via the LIN. The zoom is generated by the rear parking aid camera on top of the video image that is sent to the APIM.

The fixed and active guidelines are generated by the rear parking aid camera and are not selectable by the driver.
