Air Bag Deactivation Switch: 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 located in the integrated control panel (ICP) 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 deactivated (OFF). Some exceptions to this are made in certain scenarios such as 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 cases, the PAD indicator is unlit when the passenger air bag module is activated (ON).

When the ignition switch is in the RUN 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 illuminate/not illuminate within 1.0±0.5 seconds of a change of state from the OCS system.

When an OCS system fault is present, the SRS defaults the passenger air bag module to ON (activated) regardless of the size of the occupant in the front outboard passenger seat. The PAD indicator will be unlit.
