Item Outline
SAS control module
•
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.
Crash zone sensor
•
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)
Side air bag sensor
Driver-side air bag module
•
Dual inflators, inflator 1 and inflator 2, have been adopted in
accordance with the front air bag system two-step
deployment control.
Passenger-side air bag module
Side air bag module
•
Chest-protection type side air bag module is used in
accordance with the adoption of the curtain air bag module.
Curtain air bag module
•
Adopted to improve safety in lateral collisions.
Pre-tensioner seat belt
•
Piston-type pre-tensioner seat belt has been adopted.
Seat track position sensor

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.
Air bag system warning light
•
LED has been adopted.
Seat weight sensor
•
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.
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.
