Air bag light flashing

According to the Nissan service manual the procedure to Reset the Air Bag System Warning Light is as follows:
1. Turn ignition switch from OFF to ON.
2. Air Bag warning light is on for 7 seconds and turns off, turn the ignition switch OFF within 1 second after the light goes out.
3. After ignition switch is turned OFF, wait for more than 3 seconds.
4. Repeat steps 1 to 3 twice. (Perform 3 times in total.)
5. Turn Ignition switch ON.
6. The SRS light should be reset.
If the warning light can not be reset I'd suggest you contact your Nissan dealer for more information and a proper diagnostics check as there be a fault with the airbag system.

you may have a problem with the clock spring or spiral cable as nissan calles it. it is a part of the air bag system and also horn signal runs into and out of it.if that part is bad, your air bag light will flash and your horn will not work. has anyone been doing any repairs inside of the steering wheel?? it may just be unpluged. if you are going to tackle this your self to look inside of the steering wheel, make sure you disconnect the battery for at least 3 minutes, befor you start playing with the air bag. you dont want to blow it up.

the air bag has a clockspring that is probably broken, but I'd check for a sensor that is not hooked up before I replaced it.

It is a short in one of the ignition wire, car start, and while drive wire get hot and in
short circuit, drain the battery and posible burn the diodes in the alternator.
Identify wire and replace

If the air bag light is flashing- that means there is problem with your SRS air bag system. It stored a code in the computer and wont turn off untill the problem is fixed or cleared manualy with a scan tool- note if you choose to clear the code and turn off the light with a scan tool- if the problem with the system is still there the computer in your car will notice it and store another code and the light will come right back on. also Note that if the air bag light or SRS light is on while driving that system is shut down and your air bags WILL NOT go off if you get into an accident. (the same rules apply if your ABS- anti lock brake light is on- the ABS system will not work) the most common problem with the Altimas and air bag codes are the clock spring assembly located behind your steering wheel- (not the air bag itself on the steering wheel) but there is a round thing that turns with a wire connected to it. you have to remove the steering wheel to service. Best bet - go somewhere that has a scan tool and read what code the computer stored. It will tell you what part of the system has the problem.

It sounds like the air bag relay switch is going bad have it tested at either autozone or the partd store that is in your area.

Try this:
5. If “AIR BAG” warning lamp operates as [as I said before], turn ignition switch “OFF” to reset from Diagnosis mode
1. Turn ignition switch “ON”.
2. After “AIR BAG” warning lamp lights for 7 seconds, [i.e. when it stops running solid and starts flashing] turn ignition switch “OFF” within 1 second. [DO NOT SWITCH IT TO LOCK, SWITCH IT TO ACC]
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 two times. (Perform 3 times in total.)
5. Turn ignition switch “ON”.
SRS is now in Diagnosis mode.
Try it a few times. If you can't get it to work, have someone else try. If you STILL can't get it to work, check your battery voltage. It might be low.
In diagnosis mode, you're going to hope the light flashes slowly. 2 seconds off, 3 seconds on, and repeats. If your light does this, this means that the computer detected a previous error that hasn't been erased. This is good.
to User mode and to erase the memory of the malfunction.
6. Turn ignition switch “ON”. “AIR BAG” warning lamp operates in
User mode. [it should stay on for 7 seconds, then go off, like normal.]

Airbags dont need to be replaced. There is an issue with the electrical that connects to the airbags. This is not a DIY project because if you connect the wrong wires it could cause the bags to deploy and you could get seriously hurt - or cost $3,000 if your lucky to replace the bags

you did'nt state year, make, model. If you are talking about the seat belt light, check your seat belt(the one with the push/release button. check this top to bottom for a broken wire. ckeck under the seat the harness may be damaged as well. If it is the air-bag light bring it to your mechanic. air-bag circuits should be touched without the right knowledge and tools.

Try clearing the codes & see if it returns. I do not see a code fault 10. Starts at 12.

Section 01-20B: Restraints, Passive — Supplemental Air Bag System 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DIAGNOSIS AND TESTING Diagnostic Trouble Code Clearing Procedure to Clear Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory.
Normal Operation
The air bag diagnostic monitor (14B056) continually checks the air bag system for readiness. When a fault condition is detected, the DTC associated with that fault is stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM). After writing the DTC to NVRAM, the air bag diagnostic monitor signals the fault by flashing the appropriate diagnostic trouble code on the air bag indicator. The diagnostic trouble code written to NVRAM is permanently stored in the air bag diagnostic monitor until cleared by the diagnostic trouble code clearing procedure.

• Upon each cycle of the ignition switch (11572) , the air bag diagnostic monitor checks for diagnostic trouble codes written in NVRAM. If any diagnostic trouble codes exist in NVRAM, the air bag diagnostic monitor will then check to see if these fault conditions are still present.
• If the conditions of the diagnostic trouble code in NVRAM are still present, then the air bag diagnostic monitor will use the air bag indicator to flash out the diagnostic trouble code number that was written in memory.
• If the conditions of the diagnostic trouble code are not still present (indicating an intermittent or serviced fault), the air bag diagnostic monitor will use the air bag indicator to flash out a DTC which is the sum of the diagnostic trouble code in NVRAM plus 40.

Example: Due to corrosion, high resistance develops on the driver side air bag circuit. The air bag diagnostic monitor stores a diagnostic trouble code 32 in NVRAM. Upon each cycle of the ignition switch , the air bag diagnostic monitor checks the resistance of the driver air bag circuit.

• If the resistance is still high, the air bag diagnostic monitor causes the air bag indicator to flash out a DTC 32.
• If the resistance falls within the normal range due to service or an intermittent condition, the air bag diagnostic monitor causes DTC 72 to be flashed on the air bag indicator.

Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVRAM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.

1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.

1. Cycle the ignition switch to OFF and then to RUN.

1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.

1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).

1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.

1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).

1. Release short on Circuit 631 (TAN/RED STRIPE) to Circuit 57 (BLACK). This short must be released within 25 seconds after the diagnostic monitor tone sounds. Diagnostic trouble code is now cleared from NVRAM. Next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.
