COMPONENTS DESCRIPTION CHART

Switch/button connection	Application
Direct	Seat adjustment motor is directly activated.
Resistance-coded	The seat module reads in the switch directly and effects the request triggered by the switch.
LIN-Bus	The seat module cyclically requests the status of the switch and effects the request triggered by the switch.
LIN bus > K-CAN2	For example, the buttons in the armrests are connected to the footwell module or the junction box electronics. The control units evaluate the button status and send it via the K-CAN2. The signal is transferred from the central gateway module to the K-CAN.
Control unit > K-CAN	For example, the button status for the seat heating in the front seats is evaluated by the integrated automatic heating and air conditioning system and issued via the K-CAN. For example, the button status for the active seat ventilation in the rear seats is evaluated by the automatic rear-compartment air conditioning and issued via the K-CAN.
