Driver Seat Belt Pretensioner, Passenger Seat
Belt Pretensioner
Driver seat belt pretensioner, passenger seat belt pretensioner
module includes a shell, a detonating device and gas
generating agent. The ignition device is part of the seat belt
pretensioner deployment circuit. When a vehicle front or side
collision impact force is large enough, the airbag control
module will command (electric current signal) the electric
current flow through the ignition to detonate the gas generating
agent and rapidly produce a large amount of gas. The reaction
produced gas will make the seat belt pretensioner quickly
tighten the seat belt. Airbag control module harness connector
(airbag deployment circuit) has a short film. When the
connector is disconnected, the airbag deployment short circuit
will prevent the airbag accidental deployment during the repair.
Driver Side Airbag, Passenger Side Airbag
Driver side airbag and passenger side side airbag are located
in the driver seat back and passenger seat back respectively.
Side airbag modules include airbags, detonating devices and
gas generating agent. The detonating device is part of the
airbag modules deployment circuit. When a side impact force
is large enough, the side collision sensor will detect the collision
and send a signal to the airbag control module. Airbag control
module will compare the signal from the side collision sensor
with the value in the memory. When the signal exceeds the
stored value, the airbag control module commands the side
airbag to deploy. When the passenger side collision happens,
it requires the driver side airbag, driver curtain airbag are not
deployed, while the passenger side airbag, passenger curtain
airbag deploy. Airbag control module continuously monitors
whether the airbag deployment circuit is faulty. In the event of
a fault, it will light the airbag indicator. Airbag control module
harness connector (airbag deployment circuit) has a short film.
When the connector is disconnected, the airbag deployment
short circuit will prevent the airbag accidental deployment
during the repair.
Driver Curtain Airbag, Passenger Curtain
Airbag
Driver curtain airbag, passenger curtain airbag are located on
the left and right roof rails, from the A-pillar extends to the C-
pillar. Curtain airbag module includes airbags, a detonating
device and gas generating agent. Detonating device is part of
the curtain airbag deployment circuit. When a side impact force
is large enough, side collision sensors will detect the collision
and send a signal to the airbag control module. Airbag control
module will compare the signal from the side collision sensor
with the value in the memory. When the signal exceeds the
stored value, the airbag control module commands the curtain
airbag to deploy. When the passenger side collision happens,
it requires the driver side airbag, driver curtain airbag are not
deployed, while the passenger side airbag, passenger curtain
airbag deploy. Airbag control module continuously monitors
whether the airbag deployment circuit is faulty. In the event of
a fault, it will light the airbag indicator. Airbag control module
harness connector (airbag deployment circuit) has a short film.
When the connector is disconnected, the airbag deployment
short circuit will prevent the airbag accidental deployment
during the repair.
Clock Spring
Airbag clock spring is located in the steering column below the
steering wheel. When the steering wheel rotates, the clock
spring maintains continuous electrical contact between the
airbag deployment circuit and the driver front airbag. The
steering wheel clock spring connector is equipped with a short
film which can short the driver front airbag deployment circuit,
in order to prevent the airbag accidental deployment during the
repair.
Airbag System Wiring Harness
Airbag system connects sensors, the control unit, inflatable
modules, airbag deployment circuits and CAN bus serial data
circuits together through the waterproof harness. The airbag
system deployment circuit connectors are yellow to facilitate
identify them. For airbag system wiring harness repair, please
refer to the appropriate testing and repair procedures in this
manual.
Steering Wheel and Steering Column
The steering wheel and steering column have adopted energy-
absorbing designs to absorb energy when the driver and the
steering wheel come into contact. When a vehicle front collision
happens, the driver may be contacted directly with the steering
wheel, or the impact will be loaded into the steering wheel and
steering column. The steering column will shrink down to
absorb some of the collision energy, thereby help to reduce the
driver personal injury. After a collision, you must check the
steering wheel and steering column damage.
