Control Module
The Parking Assistance Camera (PAC) is located to the left in the cargo compartment, on the side of the Trailer module (TRM).
The Parking Assistance Camera (PAC) has three connections.
One connection for the video camera, one video output to the Infotainment control module (ICM) and one CAN connection.
The Parking Assistance Camera (PAC) uses the connection for the video camera to send control signals to the camera via an internal communication interface similar to LIN-protocol, receive LVDS video signals, and to supply the camera with power.
The video output is used to transfer NTSC video composite signals to the display screen on the Infotainment control module (ICM).
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).
Parking Assistance Camera (PAC) is activated in ignition position II when reverse gear is engaged (on the condition that the parking camera is activated in the menu). When Parking Assistance Camera (PAC) is active, the camera is also active.
Parking Assistance Camera (PAC) switches off:
- in ignition positions greater than II
- if ignition position changes to 0 or I
- when reverse gear is disengaged for longer than 5 seconds (if the parking brake has not been activated via the button in the Climate control module (CCM).
Settings can be made for the Parking Assistance Camera (PAC) to display bars (to show distance), selection of rear objects and guide-lines for reversing. The guide-lines can be activated separately. Bars for viewing and marking rear objects requires that the guide-lines are activated.
If a trailer is connected electrically to the vehicle, neither bars nor guidelines will appear.
