The liftgate must remain closed for correct operation of the video camera system.

NOTE: The guidelines will not appear if the liftgate is ajar.

The video camera system has 5 video features that are controlled in the FDIM :

Fixed guidelines - this feature assists the driver with backing into a parking space or aligning the vehicle with an object.
Active guidelines - this feature projects the intended path of the vehicle based upon steering wheel input.
Visual park aid alert - this feature assists the driver to visually see the object causing the parking aid system to sound.
Manual zoom - this feature assists the driver with connecting or towing a trailer allowing the driver to manually zoom closer to an object behind the vehicle.
Video camera delay - this feature allows the driver to see the image behind the vehicle after the vehicle is shifted out of REVERSE and the vehicle speed has not exceeded 8 kmh (5 mph). The image will not be displayed if the vehicle is shifted into PARK.

For each one of these system features except the camera delay feature, the APIM sends requests to the BCM. The BCM sends the commands to the video camera over a dedicated LIN. The video camera delay feature is controlled with in the APIM.

All of the video camera features are enabled and disabled within the FDIM menu screen. The video camera delay feature keeps the image displayed on the FDIM until the vehicle reaches 8 kmh (5 mph) when the vehicle is shifted out of REVERSE or if any button on the FDIM is pressed. The video camera fixed guidelines feature displays guidelines on top of the video image to assist the driver with alignment of the vehicle. A dashed line on the displayed image represents the center of the vehicle and 3 color-coded lines (red, yellow, green) identify different zones between the rear of the vehicle and objects.

The color-coded lines cannot indicate accurate or consistent distances between objects located behind the vehicle and at the rear of the vehicle. This normal condition is due to variances in vehicle ride height, including, but not limited to, vehicle loading.

The manual zoom feature is controlled by the video camera. The manual zoom feature has 3 zoom levels that are only active when the vehicle is in REVERSE. If the manual zoom feature is enabled and the vehicle is shifted out of REVERSE the manual zoom feature is disabled. The manual zoom feature must be re-enabled the next time the vehicle is shifted into REVERSE.

The BCM and the video camera communicate on a LIN which is a dedicated single wire communication network.

The messages sent from the BCM to the video camera are:

transmission selector (PRNDL) status (REVERSE/not REVERSE only)
liftgate ajar status
camera configuration data
display manual zoom request
parking aid audible warning status
parking aid sensor distance to object data

The messages sent from the video camera to the BCM are:

camera status
display zoom status
camera part number data
visual park aid alert status
fixed guideline status
