Air Bag System; Air Bag System Outline - Mazda CX-9 2007 Service Highlights

AIR BAG SYSTEM OUTLINE

• The air bag system is a device that supplements the passenger restraint function of the seat belts. The air bag
system will not have the designed effect if the seat belts are not worn properly.
• The air bag system is composed of the following parts:
Item
SAS control module
Crash zone sensor
Side air bag sensor
Driver-side air bag module
Passenger-side air bag module
Side air bag module
Curtain air bag module
Pre-tensioner seat belt
Seat track position sensor
PAD indicator
Air bag system warning light
Seat weight sensor
Seat weight sensor control module

AIR BAG SYSTEM

• Two-step deployment control has been added to the front air
bag system (driver and passenger side) deployment control.
• A rollover control has been adopted which operates (deploys)
the curtain air bag module and pre-tensioner seat belts during
a vehicle rollover.
• Recognizes actually equipped air bag module or pre-
tensioner seat belt based on module configuration.
• Detects degree of impact, converts to an electrical signal, and
sends the signal to the SAS control module. For operation,
refer to SAS control module, Air bag module and pre-
tensioner seat belt deployment operation. (See 08-10-6 SAS
CONTROL MODULE CONSTRUCTION/OPERATION)
• Dual inflators, inflator 1 and inflator 2, have been adopted in
accordance with the front air bag system two-step
deployment control.
• Chest-protection type side air bag module is used in
accordance with the adoption of the curtain air bag module.
• Adopted to improve safety in lateral collisions.
• Piston-type pre-tensioner seat belt has been adopted.
• Detects the seat track position of the driver's seat, and sends
a corresponding signal to the SAS control module.
• PAD indicator has been adopted to inform driver and
passenger of the deployment standby status of the
passenger-side air bag module, passenger-side side air bag
module, and passenger-side pre-tensioner seat belt.
• LED has been adopted.
• Measures the compression weight of the load applied to the
passenger-side seat by the distortion amount using two seat
weight sensor and sends an electrical signal corresponding to
the distortion amount to the seat weight sensor control
module.
• Based on the electrical signal sent from the seat weight
sensor corresponding to the distortion amount, calculates the
total seated weight to determine the passenger, and sends
the determination result to the SAS control module.
