Passenger Air bag module (hereinafter referred to PAB) located at passenger side crush pad protects passenger by reducing impact of collision.
PAB is consist of air bag, pat cover 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 PAB 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 B1355 if there is a short to power in PAB harness.
*In this case, SRSCM checks if there's any fault in circuit by sending current for a while.
