Hyundai Sonata LF: SRSCM / Occupant Classification Sensor (OCS) Description and Operation
In order to make normal activation of airbag system, SRSCM
detects DTC(s) for the Occupant Classification System (OCS). If the seat
is occupied, OCS detects passenger presences status and send signal to
SRSCM via CAN.
SRSCM recognizes the signal as 2(two) different
classifications; that is, 1(Empty or small occupant with child restraint
system), 2(Occupied with large occupant and small occupant).
With these signal, ACU determines whether it needs to deploy the PAB(Passenger Airbag) or not.
