Communication Error - Hyundai GENESIS COUPE BK 2010 Manual

Communication error

General Description
The system is intended to classify the occupancy status of the front passenger seat in a motor vehicle based upon the
measured force on the bottom seat cushion.
The system also communicates to the SRSCM whether to allow or inhibit the deployment of the passenger
airbagsand/or pretensioner based upon this status.
The System also measured dynamic responses of the occupant.
This information is used to idenitify when a child seat is cinched down tightly with the seat belt, and to alsodetermine if
the seat is unoccupied.
However, the dynamic measurements are not intended, nor capable of monitoring the seating position of the
occupant,nor can they determine the proximity of the occupant to the inflator modules.
The system should not be confused with an occupant position recognition system, or any other occupant
proximitysensor.
The Passenger Occupant Detecting System (PODS) utilizes bladder placed between the passenger seat cushionand
suspension to measure the occupant's loading force on the vehicle seat.
The bladder is connected to pressure sensor and ultimately to an electronic control unit (ECU),both of which are
mounted under the seat pan.
The quantitative force determined by the system is compared to a given threshold for determination of passenger
airbag suppression.
DTC Description
The SRSCM sets DTC B1493 if there is any error in communication between OC Passenger Sensor and SRSCM.
