How The Airbag System Works
• The Occupant Restraint Control (ORC) module de-
termines if a frontal, side, or rollover collision is severe
enough to require the airbags to inflate. The front
airbag inflators are designed to provide different rates
of airbag inflation from direction provided by the
ORC. The ORC may also modify the rate of inflation
based on the occupant size provided by the Occupant
Classification module. The ORC will detect roll over,
but not rear impacts.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the instrument panel, and
the steering wheel and column. If the key is in the
LOCK position, in the ACC position, or not in the
ignition, the airbags are not on and will not inflate.
• Also, the ORC turns on the “Airbag Warn-
ing Light” and “PAD Indicator Light” for six
to eight seconds for a self-check when the
ignition is first turned ON. After the self-
check, the “Airbag Warning Light” will turn off. The
“PAD Indicator Light” will function normally (Refer to
ЉPassenger Airbag Disable (PAD) Indicator LightЉ in
this section). If the ORC detects a malfunction in any
part of the system, it turns on the “Airbag Warning
Light” either momentarily or continuously. A single
chime will sound if the light comes on again after
initial start up.
