Air bag switch flashing

Need to plug in to diagnostics to find out , if the air bags have deployed in a accident then not only do u replace the air bags crash sensors and the air bag ecu aswell

Has the vehicle been in a crash or minor accident recently? Have you installed any amps or anything under the seats? Are seatbelt tensioners working properly? These are typical issues.
Here is a list of airbag codes:

You need to find out what the fault code is. It will direct you to the area responsible.

Air Bag Diagnostic Monitor
WARNING: UNDER NO CIRCUMSTANCES SUBSTITUTE ANOTHER FUSE VALUE FOR THE 10A BATTERY FUSE. ANY FUSE OTHER THAN 10A MAY CAUSE DISARMING FAILURE AND MAY RESULT IN DANGER TO THE OCCUPANTS OF THE VEHICLE. DO NOT ATTEMPT TO REPLACE THE 10A BATTERY FUSE UNTIL THE AIR BAG SYSTEM FIRST HAS BEEN DEACTIVATED (SEE DEACTIVATION PROCEDURE FOR DETAILS).
NOTE: The safing sensor is internal to the air bag diagnostic monitor (14B056) and is not replaced separately.
The air bag diagnostic monitor continually monitors all supplemental air bag restraint system (SRS) components and wiring connections for possible faults in the system. If the air bag diagnostic monitor detects a fault in the SRS when the ignition switch (11572) is in the RUN position, a diagnostic trouble code (DTC) will be displayed by the air bag indicator, located on the instrument cluster (10849).
The air bag diagnostic monitor does not deploy the air bag in the event of a collision. The LH or RH air bag sensor and the safing sensor determine when to deploy the air bag.
The air bag diagnostic monitor illuminates the air bag indicator for approximately six seconds when the ignition switch is in the RUN position and then turns the indicator off. This shows that the air bag indicator is operational. If the air bag indicator does not illuminate or the indicator stays on or flashes at any time, a fault has been detected by the air bag diagnostic monitor.
DTCs may not be displayed for approximately 30 seconds after the ignition switch is placed in the RUN position. This is the amount of time the air bag diagnostic monitor requires to perform all tests and verify system faults.
Each DTC (a series of flashes and pauses of the air bag indicator):

• Represents a two-digit number.
• Is always displayed at least twice.

If the diagnostic monitor detects a fault in the air bag system, a DTC will be written to the diagnostic monitors non-volatile RAM (NVRAM). This DTC will then cause the lamp to flash a lamp fault code (LFC) on the air bag indicator and can be retrieved with the New Generation STAR (NGS) Tester. After repair, the DTC may then be cleared from the NVRAM.
If a system fault is present and the air bag indicator is malfunctioning, an audible tone will be heard. The tone is a series of five sets of five beeps. If the tone is heard, the air bag system requires repair.
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor will attempt to remove deployment power by turning on a solid state switch to blow the 10A battery fuse 2.
If the 10A battery fuse has successfully been blown by the air bag diagnostic monitor, the air bag diagnostic monitor will not attempt to blow it again until the proper fault has been repaired and cleared (see Diagnostic Trouble Code Clearing procedures for details). The air bag diagnostic monitor will store both the unwanted deployment DTC and the loss of deployment power DTC. The loss of deployment power DTC is the highest priority.
DTCs are prioritized numerically. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After that fault has been corrected, the next highest priority fault will be displayed.
The air bag diagnostic monitor includes an internal backup power supply. This feature provides sufficient backup power to deploy the air bag in the event the battery (10655) or battery cables are damaged in a collision before safing and air bag sensors close. The backup power supply will deplete its stored energy approximately one minute after the positive battery cable is disconnected.
--------------------------------------------
The DTCs can be retrieved with New Generation STAR (NGS) Tester using the Retrieve/Clear Continuous DTCs option. Any DTCs stored in the air bag diagnostic monitor will be displayed on the NGS along with a brief description of the DTC. If no DTCs are present, the NGS Tester will display a SYSTEM PASSED message. This option can also be used to clear DTCs from the air bag diagnostic monitor memory, as long as the concern no longer exists. Once a DTC is logged into the air bag diagnostic monitor memory, it will stay in memory until 255 key cycles have been recorded or until the NGS is used to erase the DTCs. Once 256 key cycles have been recorded since the concern was last detected, the DTC will automatically be removed from memory.

To manually check air bag codes, turn the key On and push the driver's door switch (at the bottom of the B-pillar) 5 times or more within 7 seconds of turning the key ON. Then watch the air bag light flashing codes. The air bag light will come ON for 3 seconds and then give fast flashes if there is a code. Count the fast flashes as the code. So the air bag light on for 3 seconds and then 8 flashes is a code 8 for the passenger air bag circuit. after counting code clear codes and see if they come back

the air compressor is probably bad, there are companies that sell kits to eleminate the compressors and air bags with springs. I have used a few and they work ok.

Code 27 is a problem passenger airbag disconnect switch. Usual caused by the bulb next to the passenger airbag on/off key being burned out. Check out this website for instructions on replacing it, you have to solder in a new bulb or replace the whole switch assembly. http://www.automotiveforums.com/vbulletin/t72315.html

I think you have a false code stored due to your work. clear the code and you should be ok.
If the air bag indicator does not illuminate or the indicator stays on or flashes at any time, a fault has been detected by the air bag diagnostic monitor.
Diagnostic trouble codes (DTCs) may not be displayed for approximately 30 seconds after the ignition switch is placed in the RUN position. This is the amount of time the air bag diagnostic monitor requires to perform all tests and verify system faults.
Each DTC (a series of flashes and pauses of the air bag indicator):

• Represents a two-digit number.
• Is always displayed at least twice.

If the diagnostic monitor detects a fault in the air bag system, a diagnostic trouble code (DTC) will be written to the diagnostic monitor's Non-Volatile RAM (NVRAM). This DTC will then cause the lamp to flash a lamp fault code (LFC) on the air bag warning lamp and can be retrieved with the New Generation STAR (NGS) tester. After servicing the DTC may then be cleared from the NVRAM.
If a system fault is present and the air bag indicator is malfunctioning, an audible tone will be heard. The tone is a series of five sets of five beeps. If the tone is heard, the air bag system needs attention.
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor will attempt to remove deployment power by turning on a solid state switch to blow the 10A battery fuse.

If the 10A battery fuse has successfully been blown by the air bag diagnostic monitor, the air bag diagnostic monitor will not attempt to blow it again until the proper fault has been repaired and cleared (refer to Diagnostic Instructions). The air bag diagnostic monitor will store both the unwanted deployment diagnostic trouble code and the loss of deployment power diagnostic trouble code. The loss of deployment power diagnostic trouble code is the highest priority.
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor has an internal fuse that that will blow (open) automatically. This removes all power to the air bag deployment circuit.
DTCs are prioritized numerically. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After that fault has been corrected, the next highest priority fault will be displayed.
The air bag diagnostic monitor includes an internal backup power supply. This feature provides sufficient backup power to deploy the air bag in the event the battery (10655) or battery cables are damaged in a collision before safing and air bag sensors close. The backup power supply will deplete its stored energy approximately one minute after the positive battery cable is disconnected.

LFC - Lamp Fault Code, flashed on air bag indicator.

kenchyke, the shop may have disabled the air bag system to work on the car, and possibly forgot to activate it again. While this seems a bit odd to me that they could overlook this but, since it started after the work was done, you need to return it to the shop asap to have them check it out. Although the car runs fine, the abs system and the air bags won't operate, which could result in injury if you are in an accident (air bag will not deploy, abs probably disconnected).

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.

Passenger Air Bag Deactivation (PAD) Switch
The passenger air bag deactivation (PAD) switch:

• is located on the instrument panel to the right of the climate controls.
• contains a light emitting diode (LED) that indicates when the PAD switch is activated (passenger air bag disabled).
• allows the passenger air bag deployment circuit to be disabled using the ignition key.
• should be used whenever a child safety seat is being used in the front passenger seating position.

------------------------------------------------------------------------------------------
Prove Out the System
Prove out the system means to turn the ignition switch from the OFF to the RUN position and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either:

• fail to light.
• remain lit continuously.
• flash.

The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the RUN position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and an SRS fault exists, a chime will sound in a pattern of five sets of five tone bursts. If this occurs, the air bag indicator will need to be repaired before diagnosis can continue.
----------------------------------------------------------------------------------------
Active Commands
This command allows the technician to verify operation of the air bag indicator, passenger air bag deactivation (PAD) lamp and chime. When the air bag output command is executed, the indicator, the PAD lamp, chime and the chime are activated simultaneously for approximately four seconds. All devices are deactivated automatically.
