Side Airbag (hereinafter referred to SAB) located in driver and passenger seat protects passenger's head and shoulder. SAB is consist of air bag and inflator.
Air bag reduces impact of collision by fillied up gas.
Inflator keeps gas and uses it to deploy air bag on collision.
Never measure resistance of SAB directly, Current of measuring device may cause unexpected air bag deploy.
If you strike or spin the SRSCM at the IG “ON” state, the seat-belt pretensioner, curtain-airbag or side-airbag could be unfolded and bring on danger. Handle it with care.
The SRSCM sets DTC B1378 if the measured resistance value of DSAB circuit is more than the threshold value.
*In this case, SRSCM checks if there's any fault in circuit by sending current for a while.
