Kia Sedona (2008 year). Manual - part 42

circuit resulting in the ability of producing two separate and distinct logic level signals. 

The STPS output signal is altered by the proximity of a separate ferro-magnetic shunt, which is linked via the 
seat track. The logic signal produced is the result of the proximity device being activated or deactivated. 

When the seat is in the forward position zone of the track, the sensor gives a low current (prohibit) signal. When 
the seat is in the rear position zone of the track, it gives a high current (enable) signal.

SEAT BELT BUCKLE SWITCH (BBS) 

DESCRIPTION 

The SRSCM shall monitor the status of the driver and front passenger seat belt buckle. The SRSCM provides 
one pin each for the driver and front passenger seat belt buckle status input. The seat belt buckle circuit operates 
from internal boost voltage supplied by the SRSCM, and uses chassis ground for the signal return. The buckle 
status shall modify the SRSCM deployment. If the buckle status is unbuckled, the corresponding pretensioner 
will be deactivated. 

COMPONENTS 

CAUTION: Ensure that the harness is installed and routed properly to prevent 

damage to the wiring.

OCCUPANT CLASSIFICATION SENSOR (OCS) 

DESCRIPTION 

In contrast to the initial one-stage airbag systems, newer restraint systems involve complex logic to select, or 
alternatively suppress, various levels of safety system deployment. Inherent to an Advanced Restraint System is 
the ability to discern information regarding passenger occupancy. It is intended that these inputs be provided 
through the OC system. The object of such safety system is to reduce the risk and level of injuries by 
automatically adapting the airbag(s) and seat belt pretensioner to the driving status of the vehicle, its occupants, 
and the crash severity. The current OC system covered in this specification continually senses and classifies the

damage to the wiring.
