DAB (Driver Air Bag) PA Airbag System Resistance: All-fire current: 1.2A for 3ms. No-fire current: single pulse of 0.4A for 10 sec Cyclic test current: 100mA for continuous

PAB (Passenger Air Bag) PA Airbag System Resistance: All-fire current: 1.2A for 3ms. No-fire current: single pulse of 0.4A for 10 sec Cyclic test current: 100mA for continuous

SPT (Seatbelt Pre Tensioner) PA Airbag System Resistance: All-fire current: 1.2A for 3ms. No-fire current: single pulse of 0.4A for 10 sec Cyclic test current: 100mA for continuous

Airbag (SRS) Warning Lamp Operations Output (Active fault or historical fault counter is greater or equal to 10) (Normal or historical fault counter is less than 10)

PAD Indicator Operations Output ( PAD Lamp operation during Phase-up )

Crash Output Output The required command mode implementation is high/low voltage level. When the fire decision is made by ACU, crash output stays low voltage during 200ms like below. (Crash Output Signal)
