Description and operation

Description

The Side Airbags (SAB) are installed inside the front seat and protects the driver and passenger from danger when a side crash occurs. The SRSCM determines deployment of the side airbag by using the Side Impact Sensor (SIS) signal.

•	Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using a specified tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.
