8B-6 RESTRAINTS
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
condition 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
conduction 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.
Align the pointed marks " "! " .
Airbag Warning Lamp
The instrument cluster contains an airbag warning
indicator bulb to verify the operation of the AIRBAG
indicator and sensing and diagnostic module (SDM).
The SDM performs a turn-on test when the ignition is
turned ON. The SDM flashes the AIRBAG indicator
seven tomes by supplying an intermittent ground to
the indicator lamp circuit. After flashing seven times,
the AIRBAG indicator will turn off if no more
malfunctions have been detected.

Wiring Harness Connectors
If the sensing and diagnostic module (SDM) electrical
connector is not attached properly, a built in shorting
bar will connect the wire from airbag warning lamp with
the SDM ground wire. This turns on the AIRBAG
indicator.
To prevent deployment during servicing, additional
YAD8B070
shorting bars are located in following locations:
•
Driver airbag module connector
•
Passenger airbag module connector
•
Driver and passenger side airbag module connector
•
SDM wiring harness connector
•
Contact coil connector to airbag wiring harness
The shorting bar is only a backup safety device. Always
disable the supplemental restraints system (SRS)
before beginning any service procedure.
Belt Pretensioner
The belt pretensioner enables to retract the driver and
the passenger seat belt webbing to reduce any personal
impact when accounted a frontal collision.
