Control module




The Parking Assistance Camera (PAC) is located on the left in the cargo compartment, to the side of the Trailer module (TRM). The Parking Assistance Camera (PAC) has with three terminals. One for the video camera, one video output for the High Level Display Front (HLDF) and a CAN terminal.
The Parking Assistance Camera (PAC) uses the connection to the camera to send control signals to the camera via LIN communication, receive LVDS video signals and to supply the camera with power.
The video output is used to transfer the NTSC video composite signal to the High Level Display Front (HLDF).
The CAN terminal is used to receive necessary signals from:
- steering wheel angle sensor module (SAS)
- central electronic module (CEM)
- infotainment control module (ICM)
- climate control module (CCM)
- Parking Assistance Module (PAM)
- trailer module (TRM)
- gearbox control module (TCM)
- brake control module (BCM).
The Parking Assistance Camera (PAC) is activated in ignition position II, when reverse is engaged. When the Parking Assistance Camera (PAC) is active, the camera is also active.

Parking Assistance Camera (PAC) switches off:
- in ignition positions greater than II
- if the ignition position is less than II for longer than 15 seconds
- when reverse gear is disengaged for more than 15 seconds (for XC60, from structure week 200909, 5 seconds apply).
The Parking Assistance Camera (PAC) can be set if bars for displaying the distance to objects behind and guidelines are shown.
If a trailer is connected to the vehicle, neither bars nor guidelines will appear.
Can also be set if the monitor is to rise automatically when reverse is engaged, or if the monitor is always raised to minimize waiting time, or switch off the entire camera. Regardless of whether the monitor is raised automatically or is up all the time, the camera image is only displayed when reverse is engaged.
This is carried out using the parking camera's menu system on the monitor.
The parking camera's menu system on the monitor can be controlled using the navigation buttons on the reverse of the steering wheel or with the navigation remote control for the High Level Display Front (HLDF). The receiver for the remote control, the IR eye, is mounted on the Infotainment control module (ICM).
For further information, see Design and Function, High level display front (HLDF).

High Level Display Front (HLDF)
If the Parking Assistance Camera (PAC) is activated, an image of what is behind the vehicle is shown. Otherwise, the monitor displays navigation information or is folded away.
The High Level Display Front (HLDF) is controlled by the Infotainment control module (ICM) and the image is controlled by the Parking Assistance Camera (PAC).
When the navigation system is not active the following applies:
- The display screen goes up and the Parking Assistance Camera (PAC) displays images when reverse is activated in ignition position II.
- The monitor rises when the switch for activating the Parking Assistance Camera (PAC) is depressed.
- When reverse is disengaged, the display screen is up displaying images for 15 seconds. If the vehicle speed is greater than 10 km/h during these 15 seconds, the display screen goes down. If the navigation system is activated during these 15 seconds, these images are displayed instead.
When the navigation system is active the following applies.
- The Parking Assistance Camera (PAC) displays images when reverse gear is activated in ignition position II.
- When reverse gear is disengaged, the parking camera image is displayed for 15 seconds. If the vehicle speed is greater than 10 km/h during these 15 seconds, images from the navigation system are displayed. If the switch for activating the navigation system is pressed during these 15 seconds, the navigation system image is displayed instead.

Camera




The camera is located in the tailgate, slightly to the right of the handle.
After the installation of the camera, it must be set so that the guidelines appear in the correct position on the monitor for the High Level Display Front (HLDF). This is done with a check procedure in Volvo's diagnostic tool.
By activating the check procedure, the camera's view appears on the monitor with a semi transparent pattern that must align with the contours of the bumper, at the lower edge of the image.
The camera is only activated when the Parking Assistance Camera (PAC) is activated.
