Control Module
There is a parking assistance system to assist parking. The parking assistance module (PAM) manages components in the system and communication with other control modules.
The control module is located under the cargo compartment floor by the right-hand wheel housing.
The parking assistance module (PAM) communicates with directly connected parking sensors and with other control modules via the CAN.
The Parking Assistance Module (PAM) communicates with other control modules via CAN communication. The control module checks its calculations and all performed activations, as well as input and output signals via integrated diagnostics. When the control module detects a fault, a diagnostic trouble code (DTC) is stored. In some cases, the incorrect signals is replaced with a substitute value. Any DTCs are stored in the control module memory. The information can be read out 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 Module (PAM) is powered from the Central electronic module (CEM) via a fuse and grounded in the body.
To check whether the Parking Assistance Module (PAM) is powered and grounded, ignition position II can be activated and reverse gear engaged when stationary (on the condition that the auto activation option is activated in the menu on the infotainment control module (ICM)). The Parking Assistance Module (PAM) can also be activated via a button in the climate control module (CCM). If the screen is activated and shows an image of what is behind the vehicle, the Parking Assistance Module (PAM) is powered and grounded.
The Parking Assistance Module (PAM) realizes the Park Assist System (PAS) and Park Assist Pilot (PAP) functions.
The parking assistance system is available in three versions: Either with rear parking sensors only (4 channels) (PAS), with parking sensors front and rear (8 channels) (PAS) or with front, rear and side parking sensors (10 channels) (PAS and PAP).
