Control module




The task of the Parking Assistance Camera (PAC) is to aid with parking.
When reverse gear is engaged, with ignition on or engine running, the Parking Assistance Camera (PAC) is activated.
For XC60 (before structure week 201046) a picture is shown on the High Level Display Front (HLDF) (in the document also called screen) of what is behind the vehicle.
For S60 (11-), V60 and XC60 (XC60 after structure week 201046) a picture is shown on the screen in Infotainment control module (ICM) (in the document also called screen) of what is behind the vehicle.
The screen also shows the calculated path of the wheels. These lines adapt their direction depending on the steering angle chosen by the driver. The vehicle's calculated path starts at 0.3 m and extends at most 3.2 m behind the vehicle.
As well, the screen shows help lines that indicate the outer limits of the vehicle. These extend from 0.3 meters to 1.5 meter backward. If you change the steering wheel angle, the guidelines change for the vehicle's side ways position. If there is any object behind the vehicle that is registered by Parking Assistance Module (PAM) bars are drawn, showing how close the object is and in which area it is.
Parking Assistance Camera (PAC) in XC60, both for left-hand and right-hand versions, is located under the left front seat.
The Parking Assistance Camera (PAC) communicates both with directly connected components via LIN communication and with other control modules via CAN communication.
The control module checks its calculations and all carried out activations, input and output signals using built-in diagnostic functions. A diagnostic trouble code (DTC) is stored if the control module detects a fault. In certain cases, the incorrect signal is replaced with a substitute value.
Any diagnostic trouble codes are stored in the control module memory. The data can be read off using the diagnostic tool.
If the control module detects a fault, a diagnostic trouble code (DTC) is stored inside the control module's internal memory. At the same time, a number of values are stored. These are frozen at the time the fault occurred. Depending on the severity of the fault, certain functions may be partially or completely disengaged. Diagnostic trouble codes (DTCs) and frozen values (extended diagnostic trouble code (DTC) information) can be read off using VADIS via the data link connector (DLC) in the vehicle.
The Parking Assistance Camera (PAC) and corresponding back-up camera can be replaced separately.
For the Japanese market (only XC60), the Parking Assistance Camera (PAC), rear camera, and associated side-view camera can be replaced separately, however, the side-view camera can only be replaced in a complete rear-view mirror (glass side-view camera).
To check if Parking Assistance Camera (PAC) is supplied with voltage and grounded, ignition position II can be activated and reverse gear can be engaged when stationary (on the condition that the function is activated in the menu in Infotainment Control Module (ICM).
For S60 (11-), V60 and XC60 (XC60 after structure week 201046) the Parking Assistance Camera (PAC) can also be activated via a button in Climate control module (CCM). If the screen is activated and shows a picture of what is behind the vehicle, then Parking Assistance Camera (PAC) is supplied with voltage.

Signals
The table below summarizes the input signals to and output signals from the Parking Assistance Camera (PAC). The signal types are divided into directly connected signals, LIN communication and controller area network (CAN) communication. The illustration below displays the same information with the Volvo component designations.
