Seat Belt Reminder

The seat belt reminder (10/41) is activated when the central electronic module (4/56) receives a signal from the supplemental restraint system module (SRS) (4/9), via the control area network (CAN), which indicates that the seat belt is not fastened despite someone sitting in the front seat. The three seat belt buckles in the rear seat (3/217-219) have sensors which are directly connected to the central electronic module (CEM). If a belted passenger opens the seat belt while the vehicle is in motion, the central electronic module (CEM) will activate the seatbelt not fastened indicator.

Data is also transmitted to the driver information module (DIM) (5/1) which indicates to the driver that the seat belt is not being used in one of the front seats.
