DESCRIPTION AND OPERATION
(Left–Hand Drive Shown, Right–Hand Drive Similar)
AIRBAG MODULE
Driver Airbag Module
Caution: Tampering with the driver side airbag
module creates the risk of an injury from an unex-
pected deployment. Therefore, the driver side air-
bag module should never be disassembled.
The driver airbag module is under the center pad on the
steering wheel.
The driver airbag module contains an ignitor charge and
a gas generator to inflate the folded airbag.
D110B006
Passenger Airbag Module
Caution: Tampering with the passenger side airbag
module creates the risk of an injury from an unex-
pected deployment. Therefore, the passenger side
airbag module should never be disassembled.
The passenger airbag module is on the passenger side
of the instrument panel.
The passenger airbag module contains an ignitor charge
and a gas generator to inflate the folded airbag.
SENSING AND DIAGNOSTIC
MODULE (SDM)
The SDM

Has no user-serviceable parts.

Is under the front console assembly.

Continuously monitors the system components.

Records any faults which are discovered.
Illuminates a warning lamp that alerts the driver to
any faults.

Allows the fault codes to be retrieved with a scan tool.
The SDM controls the deployment of the airbag system
through the use of the

Arming sensor.

Capacitor.

Crash sensor, or accelerometer.
D110B007
Arming Sensor
The arming sensor is safety device made up of a dual-
contact, electro-mechanical switch that:

Acts independently of the electronic components.

Keeps the firing circuits for the airbags unarmed un-
der normal driving conditions.

Allows the airbags to deploy under the required
conditions.
Capacitor
The capacitor provides reserve power.
Crash Sensor
The crash sensor, or accelerometer, electronically rep-
resents the acceleration or deceleration of the vehicle
during a frontal impact. In this electronic representation,
the electrical signal is proportional to the acceleration or
deceleration of the vehicle.
SIR WARNING LAMP
The supplemental inflatable restraints (SIR) system in-
cludes a self-diagnostic function.
