Side Impact Sensor(SIS) is located in both side of center pillar detects broad collision.
When SIS delivers collision signal to SRSCM, SRSCM checks if safing sensor located in SRSCM detects collusion.
and if both SIS and safing sensor detects collision simultaneously, SRSCM operates side air bag.
The SRSCM sets DTC B140300 if there is any fault in PSIS circuit.
