Restraint > SRSCM > B1488 Passenger Airbag Resistance Circuit Short to Battery(2nd
stage)
General Description
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.
Dual output type airbag deploys two bags in sequence within specified time difference.
It can protect driver with less impact of gas expention force, that can reduce driver's injury
Constituent is the same as single output type airbag.
DTC Description
The SRSCM sets DTC B1488 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.
