Test H: Passenger Air Bag Circuit Short To Battery Or Ignition (DTC B1925): Description

Electronic Crash Sensor (ECS) module checks passenger-side air bag module circuit for shorts to battery or ignition voltage by monitoring voltage at ECS module harness connector terminals No. 14 (Yellow/Red wire) and No. 28 (Red wire).
