Image Display
The analog rear parking aid camera image is displayed by the audio system display when reverse (R) is selected. To determine the transmission gear position and enable the camera display, the PCM or TCM sends the gear position message to the GWM over the FD-CAN . The GWM then send the message to the BCM via the HS-CAN1 .
The analog rear parking aid camera is on any time it receives voltage (when the ignition is on), but a video signal is only generated under certain conditions. When reverse (R) is selected, the camera continuously generates a video signal. When any gear except reverse (R) is selected, the camera turns the video signal off when the vehicle speed reaches 16 km/h (10 mph), and turns the video signal on when vehicle speed falls below 8 km/h (5 mph). If the camera is not configured properly, some features may be inoperative. The camera sends the video signal on shielded twisted pair of wires to the APIM , which displays the image on the audio system display.

The messages sent from the camera to the BCM or IPMA are:
Visual Park Aid Alert
The visual park aid alert feature displays a visual highlight in the zone where an object has been detected by the rear parking aid system. This feature utilizes the parking aid sensor data from the IPMA to generate the visual highlights on the video image. When reverse (R) is selected and an object is detected by a rear parking aid sensor, the parking aid sensor data message from the IPMA is used by the APIM to generate the alert.
If the visual park aid alert feature is enabled, the feature is still operational even if the rear parking aid system has been disabled by the driver.
The on-screen alert transitions may not match changes in the audible parking aid alert tone frequency.
Fixed Guidelines
The rear parking aid 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 identify different zones between the rear of the vehicle and objects. The rear parking aid camera generates the fixed guidelines over the video image.
The guidelines are not shown when reverse (R) is not selected (video delay active).
Fixed guidelines are not shown when the liftgate is open.
The color-coded lines cannot indicate accurate or consistent distances between the rear of the vehicle and objects shown in the video image. This normal condition is due to variances in vehicle ride height including, but not limited to vehicle loading.
Active Guidelines (with Digital Rear Parking Aid Camera)
The active guidelines feature displays dynamic guidelines that correspond to the projected path of vehicle travel, based on the current steering angle. Several modules are involved in generating the steering angle data used to support the active guidelines. The PSCM monitors the steering angle sensor and sends the steering wheel angle sensor data to the ABS module via the FD-CAN . The ABS module uses this message from the PSCM to generate the steering angle message that is sent to the IPMA over the FD-CAN . The IPMA sends the steering angle data to the rear parking aid camera via the LVDS . The rear parking aid camera uses this data to generate the active guidelines over the video image.
If the steering wheel is in the straight-ahead position or if the liftgate is open, the active guidelines are not shown.
The guidelines are not shown when reverse (R) is not selected (video delay active).
If the battery has been disconnected or discharged, or a module is disconnected or replaced, the active guidelines may be inoperative until the vehicle is driven on a flat and smooth road at 32 km/h (20 mph) or more, with hands placed loosely on the steering wheel and minimal steering correction for approximately 30 seconds. If the guidelines remain inoperative, it may be necessary to disconnect the battery for 5 minutes with the driver's door open, then drive the vehicle for 8 kilometers (5 miles) in normal city driving before performing the procedure described above.

Image Display
The 360 degree view camera system is capable of generating several different views using the front, rear, LH side, RH side, CHMSL, and trailer cameras (if equipped), and the IPMA . The IPMA processes the video signals from the cameras and generates the appropriate views that are displayed on the audio system display. The views that are displayed are determined by the transmission gear selector position.
The liftgate and doors must be fully closed for correct operation of the 360 degree view camera system.
When the ignition is on and reverse (R) is selected, the rear camera views are shown on the audio system display. The Rear 360 + Normal view is shown first. Using the audio system display on-screen camera selection buttons when reverse (R) is selected the driver can cycle through the following rear camera views:
View name | Description |
---|---|
Rear 360 + Normal | Contains the normal rear camera view, shown next to a 360 degree camera view. |
Rear Normal | Provides an image of what is directly behind the vehicle. |
Rear Split View | Provides an extended wide angle image of what is behind the vehicle. |
Rear High View | Provides an image of the truck bed and can be used to align the vehicle with a fifth wheel or gooseneck trailer |
Auxiliary View (if equipped) | Provides a rear view image from the back of a connected trailer while reversing |
Trailer Reverse Guidance View (if equipped) | Provides a rear view image behind the vehicle using the side cameras, useful when reversing with a trailer. |
When the ignition is on and any gear except reverse (R) is selected, the front camera and 360 degree views are shown on the audio system display when the camera selection switch is pressed. The front images are available until the vehicle speed reaches 10 km/h (6 mph). The Front 360 + Normal view is shown first. Using the audio system display on-screen camera selection buttons, in any gear except reverse (R), allows the driver to cycle through the following front camera views:
View name | Description |
---|---|
Front 360 + Normal | Contains the normal front camera view, shown next to a 360 degree camera view. |
Front Normal | Provides an image of what is directly in front of the vehicle. |
Front Split View | Provides an extended wide angle image of what is in front of the vehicle. |
To enable the front and rear camera displays, the IPMA monitors the camera selection switch, gear position and vehicle speed messages. The PCM or TCM on vehicles with a diesel engine, sends the gear position and vehicle speed messages through the FD-CAN to the IPMA . The camera selection switch is integral to the instrument panel center stack left switch and the switch is hardwired to the IPMA .
All camera views are generated by the IPMA , using the video signals from one or more of the cameras. The video signals are sent from the cameras to the IPMA through coaxial cables. The IPMA processes the image(s) from the cameras and sends a single image with the desired view to the APIM . The IPMA creates the final video images seen at the display and applies video adjustments such as brightness and sharpness color.
360 Degree Image Composition
To generate the 360 degree view, raw video is sent to the IPMA in serialized data format, and the IPMA combines and aligns the images from all 4 cameras to produce a single overhead view that is displayed on the audio system display along with a front or rear camera view.
When
a camera or any body component that a camera is attached to is removed
or adjusted, the 360 degree view camera alignment must be performed to
create a 360 degree image.
Refer to: 360 Degree View Camera Alignment (413-13B Parking Aid - Vehicles With: Parking Aid Camera, General Procedures).

Camera Image Generation
The front and rear cameras are on any time they receive voltage (when the ignition is on), but a video signal is only generated under certain conditions. When reverse (R) is selected or the camera selection switch is pressed, the IPMA sends an enable request message to the front and rear cameras over coaxial cables via LVDS to turn the video signal output on. When any gear except reverse (R) is selected, the IPMA sends a disable request message to the cameras to turn the video signal off when the vehicle speed reaches 16 km/h (10 mph), and sends an enable request message to turn the video signal on when vehicle speed falls below 8 km/h (5 mph). If the IPMA is not configured properly, some features and views may be inoperative.
The LH and RH side cameras are on and generating a video signal any time they receive voltage from the IPMA . The IPMA sends an enable request message through coaxial cables via LVDS to the LH and RH side cameras when reverse (R) is selected and the vehicle speed is below 8 km/h (5 mph) or the camera selection switch is pressed.

A dashed line on the displayed image represents the center of the vehicle and 3 color-coded lines identify different zones between the rear of the vehicle and objects. The IPMA generates the fixed guidelines over the video image.
Fixed guidelines are not shown when the liftgate is open.
The color-coded lines cannot indicate accurate or consistent distances between the rear of the vehicle and objects shown in the video image. This normal condition is due to variances in vehicle ride height including, but not limited to, vehicle loading.
Active Guidelines
Active guidelines are only displayed on the rear camera image in Rear 360 + Normal and Rear Normal views.
The active guidelines feature displays dynamic guidelines that correspond to the projected path of vehicle travel, based on the current steering angle. Several modules are involved in generating the steering angle data used to support the active guidelines. The PSCM monitors the steering angle sensor and sends the steering wheel angle sensor data to the ABS module via the FD-CAN . The ABS module uses this message from the PSCM to generate the steering angle message that is sent to the IPMA through the FD-CAN . The IPMA uses this data to generate the active guidelines over the video image.
When the steering wheel is in the straight-ahead position the active guidelines are not shown.
Active guidelines are not shown when the liftgate is open.
If the battery has been disconnected or discharged, or a module is disconnected or replaced, the active guidelines may be inoperative until the vehicle is driven on a flat and smooth road at 32 km/h (20 mph) or more, with hands placed loosely on the steering wheel and minimal steering correction for approximately 30 seconds. If the guidelines remain inoperative, it may be necessary to disconnect the battery for 5 minutes with the driver's door open, then drive the vehicle for 8 kilometers (5 miles) in normal city driving before performing the procedure described above.
Manual Zoom
The manual zoom is only supported by the rear camera. The manual zoom is only available for Rear 360 + Normal and Rear Normal views.
The manual zoom feature has one level of zoom. If the manual zoom feature is on and the vehicle is shifted out of reverse (R), the manual zoom feature is disabled. The manual zoom feature must be re-enabled the next time reverse (R) is selected. When the driver turns the zoom on or off at the audio system display, the command is sent from the APIM via the HS-CAN3 to the GWM . The GWM then sends the message to the IPMA through the FD-CAN . The IPMA sends the manual zoom request message to the rear parking aid camera via the coaxial cable to turn the zoom on or off.
Video Delay
When the video delay is turned on, the APIM keeps the rear normal view display enabled after the transmission is shifted out of reverse (R) into any gear other than park (P), until the vehicle speed reaches 8 km/h (5 mph). With the delay off (default), the image displays until the transmission is shifted out of reverse (R).
360 Degree View Camera Alignment
To create a 360 degree overhead image from the 4 separate camera images, the IPMA must align the camera images to each other and to the vehicle. As the camera alignment is very sensitive, the alignment process is necessary any time a camera or any component that a camera is attached to is removed or adjusted.
The alignment process is completed using a diagnostic scan tool.
