Air Bag Deactivation Indicator: Description and Operation
PASSENGER AIR BAG DEACTIVATION (PAD) INDICATOR
The passenger air bag deactivation (PAD) indicator is a visual indicator used to inform the front seat occupants of the passenger air bag deactivation
state. The PAD indicator is a stand-alone lamp installed into the vehicle instrument panel in a position visible to each front seat occupant.
The restraints control module (RCM) controls the state of the PAD indicator through a direct hardwire connection, based on information provided by the
occupant classification sensor (OCS) system. The PAD indicator is lit to indicate the passenger air bag module is disabled. An exemption to this is when
the front passenger seat is determined to be empty and passenger safety belt buckle unbuckled, and therefore indication of a deactivated passenger air
bag module is not necessary. In all other cases, the PAD indicator is unlit when the passenger air bag module is enabled.
When the ignition switch is in the ON position, the PAD indicator prove-out period is initiated by the RCM. The RCM briefly activates the PAD
indicator to prove-out the indicator function and verify to the front occupants correct functional operation of the PAD indicator.
The PAD indicator will be lit/unlit within 1.0 to 1.5 seconds of a change of state from the OCS system.
When an OCS system fault is present, the RCM defaults the passenger air bag module to the last valid state received from the OCS system until the
ignition switch is turned OFF. If the OCS system fault is still present when the ignition switch is turned ON, the RCM defaults the passenger air bag
module to enabled regardless of the size of occupant in the front passenger seat. The PAD indicator will be unlit.
