PASSENGER SENSING SYSTEM OPERATION

E5U081057031N03

1. The load on the passenger-side seat is converted into an electric signal by the strain gauge built into the seat 

weight sensor, and this signal is sent to the seat weight sensor control module.

2. The electronic signals from the two seat weight sensor are used for calculation by the seat weight sensor 

control module, which divides the result and then determines whether there is an adult or child (including a 
child-restraint seat) in the passenger-side seat, or that it is empty. The determined result is sent to the SAS 
control module.

3. The SAS control module performs control based on this determined result as shown in the following table when 

the module detects a level of impact requiring operation (deployment).

×: Possible

-: Not possible

Note

• The passenger-side air bag module, the passenger-side side air bag module and the passenger-side pre-

tensioner seat belt system will be turned off as the total seated weight drops toward 30kg {66 lb} and they 
will be turned on again before the weight exceeds 42kg {93 lb}.

PASSENGER AIR BAG DEACTIVATION (PAD) SYSTEM FUNCTION

E5U081064170N01

• By operation of the PAD switch, vehicle occupants can optionally switch the passenger-side air bag module, 

passenger-side side air bag module, and the passenger-side pre-tensioner seat belt between operational 
(deployable) and inoperational (undeployable) conditions.

PASSENGER AIR BAG DEACTIVATION (PAD) SYSTEM CONSTRUCTION/OPERATION

E5U081064170N03

• Consists of the PAD switch, installed on the left side of the dashboard, the PAD indicator, installed near the 

center of the dashboard, and the SAS control module.

• With the key inserted, when the PAD switch is turned to the OFF position, electric current A from the SAS 

control module passes through the PAD switch to ground, thereby forming an off circuit. At the same time, the 
PAD indicator illuminates and operation (deployment) of the passenger-side air bag module, passenger-side 
side air bag module, and the passenger-side pre-tensioner seat belt is inhibited.

DRIVER-SIDE AIR BAG MODULE CONSTRUCTION/OPERATION

Inflator Operation
Inflator No.1

1. When the driver-side air bag module receives an operation (deployment) signal from the SAS control module, 

the igniter built into inflator No.1 builds up heat and ignites the inflammation agent.

2. The ignition of the inflammation agent causes the combustion of a gas-generating agent which releases 

nitrogen gas.

3. The nitrogen gas is cooled at the filter and the filtrate is injected into the air bag.
