Kia Rio: Weight Classification System (WCS) Description
WCS is intended to detect the occupant’s physique in order to determine
whether the passenger airbag should be suppressed or deployed. WCS classifies
the front passenger side seat by measuring physical weight loaded onto the front
passenger side seat. It is composed of 2 weight sensors of strain gauge type
and an ECU which gathers information of weight sensors, calculates the measured
weight and makes decisions of the classification of the passenger. It is installed
on the left side (inner position in vehicle) of the seat track assembly fastened
with respective mounting bolts and nuts.
Be sure to install the harness wires so they will not pinch or
interfere with other parts.
