The Occupant Classification Module (OCM) If
Equipped is located beneath the front passenger seat.
The OCM classifies the occupant into one of three size
categories based on the input from the Bladder Assem-
bly and Belt Tension Sensor. The size categories in-
clude empty, child, and adult. The OCM sends the
Occupant Classification to the ORC to identify if a
front passenger airbag is allowed. If a fault is present,
the AIRBAG warning light is illuminated.
The Passenger Airbag Disabled (PAD) Indicator
Light If Equipped indicates to the driver and
passenger when the airbag is turned OFF in the
presence of a properly seated occupant. When the PAD
indicator light is illuminated, the airbag is OFF. Also,
when the Occupant Classification System detects ei-
ther an empty seat or a weight less than the predeter-
mined occupant threshold, the ORC will not illumi-
nate the PAD indicator light even though the airbag is
turned OFF. When the ocs system detects an adult the
PAD indicator light will be off, and the airbag will be
The Belt Tension Sensor (BTS) If Equipped is
located at the outboard passenger lap belt anchor. The
BTS generates a signal based on outboard lap belt
tension. This signal is sent to the OCM to ensure that
the resultant bladder pressure increase due to applied
lap belt tension does not cause a small occupant to be
classified as a larger occupant.
The Bladder Assembly If Equipped is located
beneath the seat cushion foam. The pressure sensor
sends a signal to the OCM.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
