THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 63 • 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 Assembly and Belt Tension Sensor. The size categories include 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 either an empty seat or a weight less than the predetermined occupant threshold, the ORC will not illuminate 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 enabled. • 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 components that affect the front passenger airbag deployment. Correctly functioning front passenger seat components are critical for the Occupant Classification System 2
