Rear Side Airbag (hereinafter referred to RSAB) is located in driver and passenger side rear seat.
It protects passenger's head and shoulder in broad collision.
RSAB 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 RSAB directly, Current of measuring device may cause unexpected air bag deploy.
The SRSCM sets DTC B142900 if the measured resistance value of DRSAB 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.
