Air bag sensor for passenger side reads off when passenger in in the seat.
Occupancy detection sensor failed, passenger front seat.
The passenger-side air bag in our 2010 Legacy is turning off intermittently and spontaneously while the car is in motion, although the passenger seat is occupied by a 120-pound person. The bag is deactivating even though the seat is securely locked into position as far from the dashboard as it will move, and nothing is placed beneath the passenger¿s seat. To reactivate the air bag, it is necessary to stop, then to restart the engine, and that maneuver is frequently not feasible in either heavy freeway traffic, or on remote highways that lack shoulders. The rebooting procedure indicates that the problem is not any sensor for the seat¿it is a problem with the computer operating the air bag. The dealer is unable to treat this problem.
The 2010 Subaru Legacy gt has a defect in the sensor that determines weight in the passenger seat. This sensors function is to turn the airbag on or off depending on the amount of weight in the seat. With a 114 pound woman in the passenger seat, the automatic airbag sensor does not signal for the airbag to be ready to deploy and continues to be in the off mode. After taking the vehicle to multiple Subaru dealerships, I was informed that the needed weight to turn the airbags to the on mode was 17 pounds. My 114 pound wife is far more than 17 pounds but the airbag sensor still does not trip to the on mode. I am worried that a passenger will not be protected in a possible crash.
