Overview

The video camera system visually aids the driver while reversing or reverse parking the vehicle. The image of the area behind the vehicle is displayed in the FDIM . The video camera system is controlled though the FDIM . Refer to the Owner's Literature for information on video camera system operation.

Module Network Input Messages — BCM

Broadcast Message	Originating Module	Message Purpose
Steering wheel angle	SCCM	Used to create the vehicle intended path on video display. Sent to the video camera via the LIN circuit.
Transmission in reverse	PCM	Used to enable the video display. Sent to the video camera via the LIN circuit.
Parking aid range to object	PAM	Used to highlight the zone where an object is detected. Sent to the video camera via the LIN circuit.
Backup camera commands	APIM	Used to command the static and active guidelines status, zoom level and object distance sent to the video camera via the LIN circuit.

Image Display

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

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. The image will not display if the vehicle is shifted into PARK.

For each one of these system features, except the camera delay feature, the BCM sends backup camera commands to the video camera. The video camera delay feature is set in the FDIM and controlled by 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.

NOTE: 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 in the FDIM 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 (REVERSE) status
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

Visual Park Aid

The visual park aid alert feature utilizes the 4 parking aid sensor inputs from the PAM and the video camera image. When the transmission selector is in REVERSE and an object is detected in the path of the parking aid sensor, parking aid range to object data is sent from the PAM through the BCM to the video camera.

The visual alerts are red, yellow or green and appear as highlights on top of the displayed image to indicate which zone the object is detected. The highlighted visual alerts are still operational if the parking aid system is disabled within the IPC and the visual alert feature is enabled.

Active guidelines display the intended vehicle path based upon the steering wheel angle.

Component Description

Video Camera

The rear video camera system is active with the ignition in RUN and the transmission selector in REVERSE. The video camera receives commands and sends status over a dedicated LIN to the BCM . The video camera is programmable and is configured through the BCM using a scan tool. The video camera configuration can be performed using a scan tool under Body > RVC configuration.
