Driver side air bag did not deploy in accident but passenger side did this was in a 2003 lincoln ls

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.

Front air bags are not designed to deploy in side impact, rear impact or rollover crashes.There are several reasons why your air bag may not have deployed during a crash. The first reason is that perhaps your crash is not the type of accident where air bag deployment would be helpful. For frontal air bags, this includes many, but not all, side impacts, rear impacts and rollovers. This category also includes minor accidents in which the driver and front passenger (if there was one) did not suffer any significant injuries requiring medical treatment. Many people do not realize there are a lot of side air bags that do not deploy during a rollover accident, even when the vehicle rolls onto its side. That is because those side air bags do not include an appropriate crash sensor that can detect rollover crashes.

In the steering wheel and passenger side dash.Due to the age of the vehicle probably doesn't have the curtain "side" airbags.The airbags were designed primarily for head on collisions. Here is some useful information to why the may have not deployed courtesy of http://www.asashop.org/autoinc/dec2001/collision.htm
How Air Bags Work To have a frontal (driver or passenger) air bag deploy, certain criteria must be met. One of these criteria is that the frontal impact must be within a 60-degree window, occurring within 30 degrees from the vehicle's centerline. Another key element is that the crash forces are equivalent to a head-on collision with an immovable barrier at 10-15 miles per hour. Because a typical automobile accident only lasts about 0.125 (1/8th) of a second, air bags deploy within 15 to 20ms after the initial crash impact. To create a protective cushion between the occupant and the vehicle's interior, the air bag inflates at speeds up to 200 mph within approximately 30ms after impact. This allows the occupant to contact a fully inflated bag within approximately 45 to 50ms after the initial crash impact. Approximately 100ms after impact the bag deflates.

in the U.S. the airbags are programmed to deploy @ 9mph(roughly the same as hitting a kerb hard.)so if the airbag went off you would not know if you hit a pothole, unless you went back to look....dont know any makers airbags that have recalls applied to them.
think of the litigation if there were...........

that meant your restrain system is malfunctioning. those honda had lots of problem with seat belt switch.
have your car to check to see what is wrong, because if you have an accident your air bag will not deploy

If the air bag light is on there is a problem with the air bag. The light means the air bags will not deploy in an accident. Only a qualified tech should work on air bags.

replace the air bag and the sensor that was hit

The passenger side airbag is a lot easier then driver side. Take the glove box out and you will see two 10mm bolts holding it in place. When you open the passenger side front door, remove the panel on the side of the dash and you will see yellow connectors.The 1 closest to the front is attached to the air bag, it is clipped into the frame. Just pull it loose and take it out and your done. For the Driver side, it takes a skinny T27 to remove the two star bolts, then just disconnect the horn red clip and ground and install new airbag. The module is located under the passenger seat, underneath the carpet. Kinda stupid but thats where its at. You also need to replace the front impact sensor located behind the grille on the back side of the metal bar to each side. Follow the hood latch down. Also just to make sure, you know to disconnect the battery before you do all this. You don't want new airbags to accidentally deploy.

first, you need to read the Lamp Fault Code, LFC from the flashing light. Here's how:

Lamp Fault Codes
When the restraints control module (RCM) detects a system fault, it will cause the air bag indicator to flash a coded sequence: a lamp fault code (LFC). The code is two digits. The first digit is flashed with a 0.5 second interval between pulses. There is a 2 second pause before the second digit is flashed, which also has a 0.5 second interval between pulses. There is a 5 second pause between each display of an LFC.
Each LFC is flashed five times after which the air bag indictor will remain lit for the remainder of the key-on cycle. If there are multiple LFCs, each LFC will flash in order of priority.
-------------------------------------------------------
The fault could be in the air bag circuits, the canopy circuits, the pretensioner circuit on the seat belts, etc.
Report back with code.

here's some of system.

Had the same problem, found the wire disconnected under the driver seat (there is a yellow plug and with one red wire, which is fine, and one green wire, which is broken. Fixed the wire, light went off.
