PASSENGER SENSING SYSTEM OPERATION
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).
Determined result Determined weight
Approx. 42 kg {93 lb} or
Adult
more
Child (including Approx. 30 kg {66 lb} or
child-restraint seat) less
Empty Approx. 0 kg {0 lb}
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}.
