Image Display
The rear parking aid camera image is displayed by the interior rear view mirror, FCDIM, or FDIM when reverse gear is selected. To enable the display when reverse gear is selected for vehicles with an interior rear view mirror display, the mirror is receives voltage from the BCM on the reverse lamps circuit. To determine the selector lever position and enable the camera display on all other vehicles, the PCM sends the gear position message to the GWM on the HS-CAN1. The GWM then sends the message to the APIM or FCDIM via the HS-CAN3.
The 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 gear is selected, the camera continuously generates a video signal. When any gear except reverse 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 wires directly to the display.
The following parking aid camera system features are driver selectable:
- Visual park aid alert -- assists the driver to visually see the object causing the parking aid system to sound. (centerstack infotainment display only)
- Manual zoom -- allows the driver to manually zoom the image. (centerstack infotainment display only)
- Video delay -- allows the driver to see the image behind the vehicle after the vehicle is shifted out of reverse into any gear other than park.
The following camera system features are not driver selectable:
- Fixed guidelines -- assists the driver with aligning the vehicle with an object.
- Active guidelines -- displays the intended path of the vehicle based upon steering wheel input.
On vehicles equipped with a centerstack infotainment display, the display settings menu is used to turn the visual park aid alert and video delay on and off. The visual park aid alert and video delay features are generated within the FCDIM or APIM.
To turn the manual zoom feature on and off, the driver uses an on screen button while reverse gear is selected. The driver generated commands originate at the FDIM (which is hardwired to the APIM), or FCDIM. The APIM or FCDIM sends the driver generated commands over the HS-CAN3 to the GWM. The GWM then sends the commands to the BCM on the HS-CAN1. The BCM sends the zoom command to the rear parking aid camera via the LIN circuit. The zoom is generated by the rear parking aid camera.
The fixed and active guidelines are generated by the rear parking aid camera and are not selectable by the driver.
