Parking Assistance System
The parking assistance module (PAM) (4/86) helps the driver when parking. Information from a number of sensors allows the control module to warn of objects close to the vehicle. A sound is transmitted through the loudspeaker which is connected to the integrated audio module (IAM).
The rear sensors (7/131, 7/132, 7/133 and 7/134) are active when the ignition is on in position II and back-up gear (R) is selected and no trailer is electrically connected to the vehicle. The sensors are deactivated automatically when the gear selector lever is moved from back-up gear (R) or a trailer is electrically connected to the vehicle. The sensors detect objects at a distance of 1.5 meters. A beeping sound is heard from one of the rear loudspeakers. The sound signal becomes more frequent as the distance to the object reduces. The sound is constant at distances below approximately 30 cm.
The front sensors (7/204, 7/205, 7/206 and 7/207) (option) are active when the ignition is on in position II and gear R is selected, or when the ignition is on in position II and the car is driven forwards at speeds below 10 km/h. The sensors are automatically deactivated when the car is driven forwards at above 15 km/h. On cars with automatic transmissions, the sensors are deactivated if P is selected, irrespective of speed. The sensors detect objects at a distance of 0.8 meters. A beeping sound is heard from one of the front loudspeaker on the driver's side (16/4). The sound signal becomes more frequent as the distance to the object reduces. The sound is constant at distances below approximately 30 cm.
The Parking Assistance Module (PAM) transmits information to the Infotainment control module (ICM) (16/1.2) on the controller area network (CAN) if parking assistance is active or not.
A text message is displayed in the infotainment control module (ICM) when the parking assistance system is active. The infotainment control module (ICM) transmits a signal to the audio module (AUD)/Integrated Audio Module (IAM) requesting sound from the loudspeaker.
The central electronic module (CEM) (4/56) transmits information about vehicle speed to the parking assistance module (PAM) on the controller area network (CAN).
The central electronic module (CEM) transmits information to the parking assistance module (PAM) on the controller area network (CAN). The information indicates the position of the gear selector lever (vehicles with manual transmissions).
The transmission control module (TCM) (4/28) transmits information to the parking assistance module (PAM) on the controller area network (CAN). The information indicates the position of the gear selector lever (cars with automatic transmissions).
The trailer module (4/110) (option) transmits information on the controller area network (CAN) to the parking assistance module PAM). This information indicates whether or not there is a trailer electrically connected to the tow hitch connector.
If there is a fault in the parking assistance system, the parking assistance module (PAM) transmits a message on the controller area network (CAN) to the driver information module (DIM) (5/1). The information lamp lights in the driver information module (DIM) and a text message is displayed.
