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 and the passenger air bag deactivation (PAD) switch. 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 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 proper functional operation of the PAD indicator.
The PAD indicator will be lit/unlit within 1.0 + 0.5 seconds of a change of state from the OCS system or PAD switch.
When an OCS system fault is present the SRS defaults the passenger air bag module to enabled regardless of the PAD switch status or the size of the
occupant in the front outboard passenger seat. The PAD indicator will be unlit.
The tables indicate the passenger air bag status and the PAD indicator status based on the size of the front outboard passenger occupant and the PAD
switch status.
