The trunk must remain closed for correct operation of the video camera system.
All of the video camera features are enabled and disabled within the FDIM (Front Display Interface Module) menu screen. The video camera system has 5 video features:
- Fixed guidelines- this feature assists the driver with 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 be displayed if the vehicle is shifted into PARK.
For each one of these system features except the camera delay feature, the APIM (Accessory Protocol Interface Module) receives the FDIM (Front Display Interface Module) touch inputs and sends backup camera commands to the IPM-B (Image Processing Module - B). The IPM-B (Image Processing Module - B) then sends the command to the video camera. The video camera outputs the video signal to the APIM (Accessory Protocol Interface Module) which in turn displays the video on the FDIM (Front Display Interface Module).
The video camera delay feature is controlled within the APIM (Accessory Protocol Interface Module).
The IPM-B (Image Processing Module - B) and the video camera communicate on a LIN (Local Interconnect Network) which is a dedicated single wire communication network.
The messages sent from the IPM-B (Image Processing Module - B) to the video camera are:
- transmission selector (PRNDL) 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 IPM-B (Image Processing Module - B) are:
- camera status
- display zoom status
- camera part number data
- visual park aid alert status
- fixed guideline status
Visual Park Aid
The visual park alert feature displays guidelines on top of the video image to assist the driver with maneuvering a vehicle into a space. Active guidelines are not shown when the steering wheel is straight.
The visual park aid alert feature utilizes the 3 parking aid sensor inputs from the PAM (Parking Aid Module) 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 (Parking Aid Module) through the IPM-B (Image Processing Module - B) to the video camera.
The visual alerts are red, yellow or green and appear as highlights on top of the displayed image to indicate in which zone the object is detected. The highlighted visual alerts are still operational if the parking aid system is disabled within the FDIM (Front Display Interface Module) and the visual alert feature is enabled.
Fixed Guidelines
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 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.
Active Guidelines
The video camera active guidelines feature displays guidelines on top of the video image to assist the driver with maneuvering a vehicle into a space. Active guidelines are not shown when the steering wheel is straight.
Manual Zoom
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.
Video Delay
When the video delay is turned on, the video image remains displayed after the transmission is shifted out of REVERSE until the vehicle reaches 8 km/h (5 mph). With the delay off (default) the image displays until the transmission is shifted out of REVERSE.
