71-100 WIRING - SYSTEM CIRCUIT DIAGRAM

Description:

• When the car collides with an obstacle, an fully inflated air cushion is deployed
quickly, to make the occupants inside the car throw on the air cushion due to inertia,
thus alleviating the impact applied to the occupants and absorbing the collision
energy, to reduce the risk of injury.
When the ignition switch is in position ON/ST, current flows from fuse F24 of body
fuse box to pin 5 of the airbag control module,providing power to the airbag control
module.

When a collision occurs, current outputs from pin 10 of airbag control module to
pin 1 of the clock spring, via the clock spring to the pin of driver's airbag assembly,
then from the other end of driver's airbag to pin 2 of the clock spring and back to
pin 11 of the airbag control module via the clock spring, which forms a loop to ignite
the airbag.

When a collision occurs, the current outputs from pin 18 of airbag control module
to pin 1 of the passenger's airbag, and then from pin 2 of the passenger's airbag
to pin 19 of the airbag control module, which forms a loop to ignite the airbag.

• Seat belt buckle switch
The current outputs from pin 30 of the airbag control module to pin 1 of the driver's
seat belt buckle switch,and it is grounded via pin 2 of the seat belt buckle switch,
to check if the seat belt is fastened. The current outputs from pin 37 of the airbag
control module to pin 1 of the passenger's seat belt buckle switch, and grounded
via pin 2 of seat belt buckle switch, to check if the seat belt is fastened.
• Collision signal

The current outputs from pin 50 of the airbag control module to pin 2 of the left front
collision sensor, and then from pin 1 of the left front collision sensor to pin 49 of
the airbag control module.When a collision occurs, signals will be sent to the airbag
controller.
The current outputs from pin 47 of the airbag control module to pin 1 of the right
front collision sensor, and then from pin 2 of the right front collision sensor to pin
48 of the airbag control module.When a collision occurs, signals will be sent to the
airbag controller.
