Passanger Side air bag sensor

Question moved from Spanish company Seat (pronounced See-At) to Malibu category.

The passenger seat airbag only fires in a crash if there is someone sitting on the passenger seat. There is a sensor in the seat cushion that register a person sitting there. Under the seat there will be a connector, take it apart and spray it with electrical contact cleaner.

You should have a pressure switch in the seat that only arms the passenger air bag when someone is in that seat. There should also be an override on the dash where you can disable the passenger airbag.

check fuses and relays their are different locations for air bag sensors and their is also seat belt sensors and seat switches [check the connections under the seat ]---their are sensors under the front bumper behind the valance by the radiator support also if air bag curtains passenger side between inner fender, door and door pillar the following links have information or what to look for and assist in solving your problem the recall doesn't cover your vehicle but it pertained to the passenger air bag problem as well as the 05 posting

There is no relay for the passenger side air bag . What seams to be the trouble ? There is possibly a code set in the air bag control module .
Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) The air bag supplemental restraint system (SRS) is designed to provide increased collision protection for front seat and second row outboard occupants, in addition to that provided by the 3-point safety belt system. Safety belt use is necessary to obtain the best occupant protection and to receive the full advantage of the SRS.
This vehicle line contains dual stage deployment (advanced restraint system) driver and front passenger air bag modules. These vehicles are also equipped with driver and front passenger safety belt retractor pretensioners. These vehicles can also be equipped with optional side air curtains that deploy from the A-pillar to the C-pillar upon a side impact. Vehicles with optional side air curtains are also equipped with seat side air bag modules in the front seats.
Side air curtains deploy from the headliner, protecting the first and second row outboard occupants during a side impact. Seat side air bag modules deploy from the outboard front seat backrest upon a side impact. In addition, a front impact severity sensor is mounted to the lower radiator support, a seat position sensor is mounted to the driver seat and a usage detection switch is added to the front driver and passenger outboard buckles. If equipped with optional side air curtain modules and seat side air bag modules, there are an additional 4 side impact sensors.
Vehicles are also equipped with an occupant classification sensor (OCS) system as part of the front passenger seat. The OCS system includes 2 OCS rails and an OCS module.
Passenger Air Bag Deactivation (PAD) Indicator
The passenger air bag deactivation (PAD) indicator is a visual indicator used to inform the front seat occupants of the passenger air bag deactivation state. The PAD indicator is a stand-alone lamp installed into the vehicle instrument panel in a position visible to each front seat occupant.
The restraints control module (RCM) controls the state of the PAD indicator through a direct hardwire connection, based on information provided by the occupant classification sensor (OCS) system. The PAD indicator is lit to indicate the passenger air bag module is disabled. An exemption to this is when the front passenger seat is determined to be empty and passenger safety belt buckle unbuckled, and therefore indication of a deactivated passenger air bag module is not necessary. In all other cases, the PAD indicator is unlit when the passenger air bag module is enabled.
When the ignition switch is in the ON position, the PAD indicator prove-out period is initiated by the RCM. The RCM briefly activates the PAD indicator to prove-out the indicator function and verify to the front occupants correct functional operation of the PAD indicator.
The PAD indicator will be lit/unlit within 1.0 to 1.5 seconds of a change of state from the OCS system.
When an OCS system fault is present, the RCM defaults the passenger air bag module to the last valid state received from the OCS system until the ignition switch is turned OFF. If the OCS system fault is still present when the ignition switch is turned ON, the RCM defaults the passenger air bag module to enabled regardless of the size of occupant in the front passenger seat. The PAD indicator will be unlit. For information on the OCS system, refer to Occupant Classification Sensor System in this section.
The following table indicates the passenger air bag status and the PAD indicator status based the size of the front outboard passenger occupant.

I would have the sensor in the passenger seat checked but if you have that seat leaning back more than the first of second position, a very unsafe way to sit in a vehicle, then the sensor is ok it is the way the body weight is distributed in the seat. When the passenger is laying back it sets the weight off center and essentially removes any possible safety the Airbag could provide and actually turns the airbag into a weapon during an accident, not to mention the seat belt will not work correctly and will most likely kill instead of save the life since they are going to slip right under it.

There is a sensor in the seat that is supposed to disable the air bag if a child is sitting in the seat. The weight of an adult should activate the air bag. There is something wrong with the sensor. DO NOT LET A CHILD SIT IN THE SEAT UNTIL IT IS FIXED. If the air bag deploys with a child in the seat, it could be fatal.

The passanger seat contains a sensor that detects the weight of a person when they are seated. Once the seat belt is fastened, the passanger air bag system is then activated. The sensor will not activate if a bag of groceries or a child that does not weigh enough. If it is an adult that is riding in the seat you should have it check at your local dealer.
Good luck.

Hi Edward your problem is probably the occupancy detector which is located in the passanger side front seat base.Its function is to detect wheather or not there is a passanger in the car.It will not allow the passanger air bag to deploy in the event of an accident if there is no passanger present.Unfortunately it cannot be repaired and will have to be replaced to do this remove the seat abd remove the seat cover and padding,[the detector is located in the seat base.
I would recommend that the air bag system is scanned to find out the fault before you buy a new detector.

no. its automatic
there are sensors in the seat to detect when someone is sitting there. it should be off if the seat empty.

Don't go to the dealer, unless you just have too much money. Call around to tire shops in your area and see if anyone has a "Bar-Tech" tool or a similar device that will reset your sensors for you and HUGE savings.
