The curtain air bag module consists of an air
bag, an inflator, and the fixing gear relating to
those parts, and is installed in the roof side
sections (from the driver’s and the passenger’s
front pillars to the rear pillars).
An inflator that does not contain sodium azide
is used.
The front impact sensor is installed on the
headlight support panel upper in the engine
room, and the analog G-sensor is housed in
the front impact sensor.
The front impact sensor transmits the coded
acceleration data to SRS-ECU. Based on the
data, SRS-ECU determines the deployment
stage of the driver’s air bag, passenger’s air
bag, knee air bag and seat belt pre-tensioner,
then energizes appropriate squib.
SRS-ECU performs the diagnosis of the front
impact sensor internal components. If a
malfunction occurs, it stores the diagnostic
trouble code.
The side impact sensors are installed to the
lower part of the center pillars on both sides
and to the quarter panel on both sides, and the
analog G-sensor is housed in the side impact
sensor.
The side impact sensor transmits the coded
acceleration data to SRS-ECU. Based on the
data, SRS-ECU determines the deployment of
the side-air bags and curtain air bags, then
energizes appropriate squib(s).
SRS-ECU performs the diagnosis of the side
impact sensor internal components. If a
malfunction occurs, it stores the diagnostic
trouble code.
OCCUPANT
CLASSIFICATION-
ECU AND
SENSOR
The occupant classification sensor is attached
to the front seat cushion cover and pad.
When The front passenger’s seat is not
occupied or the system is sensed child in the
child restraint system, the passenger’s airbag
off indicator will stay on to show that the
passenger's (front) air bag is not operational.
A sensor that detects electrostatic capacity on
the passenger's seat cushion has been
adopted to the passenger's seat occupant
classification system.
