Principles of Operation

NOTE: The tailgate must be closed for correct operation of the rear video camera system.

Rear Video Camera

The rear video camera system is active with the ignition in run and the transmission selector in the reverse position. The rear video camera receives commands and sends status to the Body Control Module (BCM) over a dedicated Local Interconnect Network (LIN). For vehicles with navigation, the rear video camera sends a video signal to the Front Display Interface Module (FDIM) on a pair of shielded video circuits, which displays the video image of the area behind the vehicle. For vehicles without navigation, the signal from the rear video camera is sent to the auto-dimming interior mirror display on a pair of shielded video circuits, which displays the video image of the area behind the vehicle.

If the vehicle is equipped with a front video camera, the rear video camera sends the rear video signal to the camera switching module on a pair of shielded video circuits. The Front Display Interface Module (FDIM) receives the signal from the camera switching module, the Front Display Interface Module (FDIM) displays the video image of the area behind the vehicle.

The rear video camera system has 4 video features (only the fixed guidelines are available with the base Instrument Panel Cluster (IPC) ). The features are:

- Fixed guidelines

- Visual park aid alert

- Manual zoom

- Video camera delay

Vehicles equipped with a base IPC (Instrument Panel Cluster) (2 rows, 14 character display), display only fixed guidelines in the auto-dimming interior mirror. The guidelines cannot be disabled..

Vehicles equipped with an optional IPC (Instrument Panel Cluster) (4.2 LCD message center) include all the rear video camera system features. The features are enabled and disabled within the message center.

For vehicles with navigation, the rear video camera features are controlled within the FDIM (Front Display Interface Module) menu screen. For each one of these system features the Audio Front Control Module (ACM) sends a network message requesting the system feature to the BCM (Body Control Module) via the Medium Speed Controller Area Network (MS-CAN).

The BCM (Body Control Module) sends the message to the rear video camera over the LIN (Local Interconnect Network). The LIN (Local Interconnect Network) is a dedicated single wire communication line that sends and receives network messages from the BCM (Body Control Module) to the rear video camera.

The messages sent from the BCM (Body Control Module) to the rear video camera are:

- transmission selector (PRNDL) 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 rear video camera to the BCM (Body Control Module) are:

- camera status

- display zoom status

- camera part number data

- visual park aid alert status

- fixed guideline status

The rear video system has a delay feature and is available on vehicles with optional Instrument Panel Cluster (IPC) and navigation. For vehicles equipped with navigation, the image is displayed in the FDIM (Front Display Interface Module) for 5 minutes or until the vehicle reaches 8 km/h (5 mph), when the vehicle is shifted out of reverse, or if any button on the FDIM (Front Display Interface Module) is pressed. The image is not displayed if the vehicle is shifted into PARK (P). For vehicles without navigation, the image is displayed in the auto-dimming interior mirror and remains on for a few seconds once the vehicle is shifted out of REVERSE (R).

The 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 visual park aid alert feature utilizes the 4 parking aid sensor inputs from the Parking Aid Module (PAM) and the rear video camera image. When the transmission selector is in REVERSE (R) and an object is detected in the path of the parking aid sensor, a network message of the distance from the parking aid sensor to the object is sent from the PAM (Parking Aid Module) to the BCM (Body Control Module) over the HS-CAN (High Speed Controller Area Network). The BCM (Body Control Module) networks the parking aid sensor message to the rear video camera over the LIN (Local Interconnect Network). 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 IPC (Instrument Panel Cluster) and the visual alert feature is enabled.

The manual zoom feature is controlled by the rear 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. For vehicles with navigation, when the FDIM (Front Display Interface Module) requests the video image to be zoomed in or out, the ACM (Audio Front Control Module) sends a zoom request network message to the BCM (Body Control Module). For vehicles without navigation, when the message center requests the video image to be zoomed in or out, the IPC (Instrument Panel Cluster) sends a zoom request network message to the BCM (Body Control Module). The BCM (Body Control Module) sends the zoom request message to the rear video camera over the LIN (Local Interconnect Network). The video image sent by the rear video camera is then digitally zoomed in or out.

Front Video Camera - F-150 Raptor Only

The front video camera system is active with the ignition in run, the transmission selector in the drive position, the vehicle is in off road mode and the Electronic Locking Differential (ELD) or 4L (4X4 LOW) is activated.

The front video camera receives commands and sends status to the Body Control Module (BCM) over a dedicated Local Interconnect Network (LIN). The front video camera sends a video signal to the camera switching module on a pair of shielded video circuits. The Front Display Interface Module (FDIM) receives the signal from the camera switching module and displays the video image of the area in front of the vehicle.

To help distinguish the front video display from the rear video display, there is an icon displayed in the upper left corner of the screen for the front camera. It is an image of a camera with the letter "F".

The front video camera system has 3 video features (only the fixed guidelines are available with the base Instrument Panel Cluster (IPC) ). The features are:

- Fixed guidelines

- Visual park aid alert

- Manual zoom

The front video camera features are controlled within the FDIM (Front Display Interface Module) menu screen. For each one of these system features the Audio Front Control Module (ACM) sends a network message requesting the system feature to the BCM (Body Control Module) via the Medium Speed Controller Area Network (MS-CAN).

The BCM (Body Control Module) sends the message to the front video camera over the LIN (Local Interconnect Network). The LIN (Local Interconnect Network) is a dedicated single wire communication line that sends and receives network messages from the BCM (Body Control Module) to the front video camera.

The messages sent from the BCM (Body Control Module) to the front video camera are:

- transmission selector (PRNDL) status

- camera configuration data

- display manual zoom request

- 4L active

- Electronic Locking Differential (ELD) active

The 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 front of the vehicle and objects.

NOTE: The color-coded lines cannot indicate accurate or consistent distances between objects located in front of the vehicle and at the front 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 front video camera. The manual zoom feature has 3 zoom levels that are only active when the vehicle is in a forward gear, and either the 4L or ELD (Electronic Locking Differential) are active. The manual zoom feature must be re-enabled the next time the vehicle is shifted into a forward gear. When the FDIM (Front Display Interface Module) requests the video image to be zoomed in or out, the ACM (Audio Front Control Module) sends a zoom request network message to the BCM (Body Control Module). The BCM (Body Control Module) sends the zoom request message to the front video camera over the LIN (Local Interconnect Network). The video image is then digitally zoomed in or out.

Camera Switching Module

The rear video camera always sends a video signal to the camera switching module. The front video camera only sends a video signal to the camera switching module when the vehicle is in a forward gear and the vehicle is in 4L or ELD (Electronic Locking Differential) modes. When the camera switching module receives only a rear video signal, the rear video signal is sent to the Front Display Interface Module (FDIM). When the camera switching module receives both front and rear signals, the front video signal is sent to the Front Display Interface Module (FDIM). An icon of a camera with the letter "F" is displayed while the front video signal is active.
