Airbag System Components
The airbag system consists of the following:
•
Occupant Restraint Controller
•
Airbag Warning Light
•
Driver and passenger frontal airbag/inflator units
•
Driver and passenger side airbag/inflator units
•
Driver and Passenger Inflatable Knee Blocker
•
Driver and Front Passenger Seat Belt Pretensioners
•
Side impact sensors
•
Front Passenger Seat Occupant Classification System
(OCS)
How the Front Airbag System Works
•
The Occupant Restraint Controller (ORC) determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC may
modify the rate of inflation based on the occupant size
provided by the Occupant Classification Module. The
ORC will not detect roll overs. The ORC monitors the
readiness of the electronic parts of the system when-
ever the ignition switch is in the START or RUN
positions. If the key is in the OFF 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 warning light
(located in the instrument cluster) and Passenger
Airbag Disable (PAD) indicator light (located in the
center console) for 4 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 indica-
tor light will function normally (Refer to “Passenger
Airbag Disable (PAD) Indicator Light” 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.
