Vehicles Equipped With Touchscreen Display

NOTE: The liftgate or cargo doors must remain closed for correct operation of the parking aid camera system.

The parking aid camera image is displayed by the FDIM when the selector lever is placed in reverse. To determine the selector lever position and enable the rear parking aid camera display, the APIM receives the transmission gear in reverse message from the PCM through the Infotainment Controller Area Network (I-CAN), with the IPC and BCM serving as gateways. The camera generates a video signal any time it receives voltage, regardless of the current configuration. If the camera is not configured properly, some features may be inoperative. The camera is supplied voltage by the BCM when the ignition is on. When the camera is on, the image signal is sent from the parking aid camera on shielded twisted pair wires to the APIM, which displays the image on the FDIM.

The camera system has 4 user-selectable features in the FDIM vehicle options menu:

Fixed guidelines -- assists the driver with aligning the vehicle with an object.
Active guidelines -- displays the intended path of the vehicle based upon steering wheel input.
Visual park aid alert -- assists the driver to visually see the object causing the parking aid system to sound.
Video delay -- allows the driver to see the image behind the vehicle after the vehicle is shifted out of reverse until the forward vehicle speed reaches 8 km/h (5 mph). The image will not be displayed if the vehicle is shifted into park.

For each of these system features, except the camera delay feature, the APIM receives the FDIM touch inputs and sends the camera commands message to the BCM via the MS-CAN, with the IPC acting as a gateway. The BCM then sends the command to the parking aid camera via the LIN. The parking aid camera generates the requested feature over the video image that is sent to the APIM.

The parking aid camera delay feature is controlled by the APIM.

The parking aid camera retains the last known setting for the fixed guidelines, active guidelines, and visual park aid alert when the ignition is turned off, therefore the rear parking aid camera settings shown in the FDIM when the ignition is off may not reflect the actual rear parking aid camera settings. Within 3 seconds of the ignition being turned on, the APIM requests the last known settings from the parking aid camera, then changes the rear parking aid camera menu selections to the settings stored in the parking aid camera. If fixed guideline, active guideline or visual park aid alert settings are changed in the FDIM when the ignition is off, the menu reverts back to the last known settings that are stored in the camera after the ignition is turned on.
