Operation

1. The load on the passenger-side front 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 four 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).
