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.
The SRSCM sets DTC B1354 if there is a short to ground in PAB harness
*In this case, SRSCM checks if there’s any fault in circuit by sending current for a while
