Make?
Model?
Year?
If you have pretensioners on the seat belt buckles, it could be a bad connection or a fired pretensioner.
I dont understand this one
I need to know the make, model, and year of your car. Like Ford Mustang 2005.
Then I can see if you have pretensioners on your seat belts. In an accident, they fire and tighten your seat belt for 2 seconds, then release. If they fire or malfunction, it turns on your air bag lamp.
It's on the inner buckle and the wire could be loose or chafed there too.
this is a 1999 mercury sable LS 3.0 DOHC the car has never been in an accident
OK, no pretensioner on your car.
If you have NGS, what is the DTC, idagnostic trouble code? Or, the lamp fault code using the IP air bag lamp?
DTC - Diagnostic trouble code, retrieved using New Generation Star (NGS) Tester 418-F048 (007-00500) or equivalent.
LFC - Lamp fault code, flashed on AIR BAG indicator.
I get bounced out when trying to configure air bag the ngs tells me ck cable connections,ck ignition make sure key is on I am unable to communakate with the crash sensors or air bags

SERVICE Circuit 70 (LB/W). REACTIVATE the system
are you getting lamp fault codes flashing?
Lamp fault codes (LFCs), if present, will begin flashing approximately 30 seconds after the ignition switch has been turned to RUN. This is the amount of time it takes the ECS to perform all tests and verify system faults, if present.
LFCs are displayed as a series of flashes and pauses of the AIR BAG indicator. LFCs are two-digit numbers.
Example: An LFC 32 is displayed as follows:
flash flash flash - (two second pause) -
flash flash - (five second pause)...
flash flash flash - (two second pause) -
flash flash - (five second pause)...
LFCs are prioritized numerically so that if two or more faults occur at the same time, the LFC with the highest priority will be displayed.
After the LFC is displayed five times, the air bag indicator will illuminate continuously until the ignition switch is cycled.
a Flashes five times per second.
b Tone will sound only if additional DTCs are present.
c Tone will sound only if additional DTCs are present.
DTC - Diagnostic trouble code, retrieved using New Generation Star (NGS) Tester 418-F048 (007-00500) or equivalent.
LFC - Lamp fault code, flashed on AIR BAG indicator.
I can not get a code for the air bag light something -IE/ GEMmodule/SRS MODULE,will not respond if I want to check DTC'S BY GOING IN TO THE PCM - NO PROBLEM FOUND, PERFORMING A DCL TEST - CKT914 PASS CKT915 PASS CKT70 - 00000012
Hello have you givin up?
been out of town. So, the air bag light on the dash is not flashing any codes either? Your ight is on steady as soon as the key is turned on?

Air Bag System Functions
The air bag electronic crash sensor (ECS) module illuminates the AIR BAG indicator for approximately six seconds when the ignition switch is turned to RUN and then turns the AIR BAG indicator off. This indicates that the AIR BAG indicator is operational. If the AIR BAG indicator does not illuminate at all, stays on continuously or flashes at any time, then a fault has been detected by the ECS.
Lamp fault codes (LFCs), if present, will begin flashing approximately 30 seconds after the ignition switch has been turned to RUN. This is the amount of time it takes the ECS to perform all tests and verify system faults, if present.
LFCs are displayed as a series of flashes and pauses of the AIR BAG indicator. LFCs are two-digit numbers.
Example: An LFC 32 is displayed as follows:
flash flash flash - (two second pause) -
flash flash - (five second pause)...
flash flash flash - (two second pause) -
flash flash - (five second pause)...
LFCs are prioritized numerically so that if two or more faults occur at the same time, the LFC with the highest priority will be displayed.
After the LFC is displayed five times, the air bag indicator will illuminate continuously until the ignition switch is cycled.
The ECS incorporates non-volatile random access memory (NVRAM) to store diagnostic trouble codes (DTCs) and retain them for 254 key cycles. The ECS will always display the highest priority DTC stored in NVRAM. DTCs may be cleared from the ECS after the fault conditions are serviced. Refer to Retrieve/Clear Continuous DTCs.
If a system fault exists and the air bag warning indicator is not functioning, an audible chime will be heard indicating a need for service. The chime is a series of five sets of five beeps. This does not indicate an LFC 55 or any other DTC. The air bag warning indicator must be serviced before LFCs can be determined.
WARNING: TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE DEPLETED BEFORE REPAIRING OR REPLACING ANY AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) COMPONENTS. TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT AT LEAST ONE MINUTE. BE SURE TO DISCONNECT AUXILIARY BATTERIES AND POWER SUPPLIES (IF EQUIPPED).
The ECS includes an internal back-up power supply. This feature provides sufficient back-up power to deploy the air bags in the event that the battery (10653) or battery cables are damaged in a collision before the safing and air bag sensors close. The back-up power supply will deplete its stored energy approximately one minute after the battery ground cable is disconnected.
The ECS incorporates an internal safing sensor. Proper mounting of the ECS and bracket assembly is critical to the function and performance of the air bag system.
The ECS is non-serviceable and must be replaced as a unit in the event of failure and after every air bag deployment.
