Finally followed up with the recall on the passenger restraint system in May. Barely anyone rides with me. Now the passenger airbag light will not light and the seatbelt on the display will not go off. Looked for disconnections, everything connected around seat. Seat belt buckled. Any clues out there?
Did the problem exist from the time it left the dealer, or did it start later?
There are two airbag lights, one for ON and one for OFF. Do either of them work? What about when you power on the car?
What happens when you unlatch the seatbelt?
Do you have a SERVICE AIRBAG message in the DIC or and airbag warning light in the center of the gauge cluster?
There are two connectors associated with the Passenger Presence Sensor. One is on the harness that comes out of the floor, connects to the seat harness, and includes wiring for the seatbelt latch. It lays on the floor and is relatively accessible. The other is clipped to the seat frame and is solely for the PPS. It is only really accessible with the seat unbolted from the floor.
From the description it appears to me that one of the connectors may be disconnected. The airbag on/off lights are controlled directly by the PPS, so if neither is on is likely that a connection is not made. Failure of the PPS has always (to my knowledge) resulted in the airbag OFF light being lit.
If unlatching the seatbelt makes a change it is the second connector, otherwise it could be either.
