• Malfunction detection and recording any faults that
are detected.
Monitor the supplemental restrain system electrical
components and set a diagnostic trouble code when
malfunction is detected.
• Display airbag fault codes
Display airbag fault codes and system status
information when connected to a scan tool.
• Self-diagnosis function
Illuminate the AIRBAG indicator to alert the driver to
any fault.
• Power supply function
Provide a reserve power source to deploy the airbags
and pretensioners if an accident has disabled the
normal power source.
Acceleromenter Sensor
The accelerometer sensor electronically represents 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.
Safety Sensor
The safety sensor is safety device made up of a dual-
contact, electro-mechanical switch that:
1. Acts independently of the electronic components.
2. Connects the acceleration sensor in series in order
to make up for the weak points in the current
electronic sensor.
Micro Controller
This device receives the impact signal from the sensor for
vehicle impact and identifies whether the current condi-
tion is necessary for airbag deployment or not. And then
the controller sends the specified currents to the airbag
ignition circuit as needed.
This device always monitors the airbag system in con-
duction with the diagnostic circuit. When it is detected
any problem, it illuminates the airbag warning indicator to
inform driver of the fault and stores the fault information.

Contact Coil
The contact coil is installed between the steering wheel
and the steering column and contains a coil that enables
to contact electrically between the airbag wiring harness,
the driver airbag module and the horn switch.
Notice
Turning the steering wheel more than three and one-
quarter turns may damage the clock spring. The
contact coil should never be disassembled and must
be replaced if the airbag have been deployed.
Notice
Turn the label of the clock spring clockwise to lock
and turn the label of the clock spring counterclockwise
approximately 2.9 ± 0.2 turns to the neutral positions
with the front wheels ahead.
