Thread: Random air bag light

So here I am making another post. Search has netted me zero help, so lets see if anyone else knows the answer.

My airbag light will illuminate randomly. It will come on for about 5-10 seconds, then go out. It only does it once I hit the bypass and stay at constant speeds of 65+. On normal rural roads,and the like, it never pops on.

Now I still do have my CEL on for P0420 because I haven't been able to change out the DP and clear the code yet. My only thoughts are it randomly illuminating are telling me of a second CEL at higher cruising speeds. Its the only thing that makes sense, but this is why I ask for help now, since I am not sure.

I'm guessing by the lack of response that no one else has seen this before. :/ Stupid car.

im just gonna say, get the CEL fixed, then worry about the next issue, the two are probably related.

Crossing my fingers that I don't have to work this weekend. That will allow me to be able to get the new downpipe installed and fix the P0420.

We'll see what I find from there. I'm just surprised no one else has ever experienced this.

i would think the 2 are not related at all, air bag light means air bag problem, cel is a engine problem, not the same cant even be read by the same scanner.

you may have a loose wire, or bad part somewhere related to the air bag.

try looking under the d/s seat, for the yellow wire, that maybe acting up on ya.

and the air bag module is under the front pass seat, under the rug, they get wet and corrode, remove it sand the the corrosion off and screw it back in.

just what coming off the top of my head.

But the airbag light ONLY comes on under highway speeds. It wont come on any other time.

Just today, I went to pass someone on a two lane, took it up to 70 to make the finish the pass, the airbag light came on about 65, and shut off as soon as I got back below 60.

When it does come on on the bypass, its only on for 5-10 seconds at a time.

it could be just a vibration that makes it come on, back to a bad connection some where i would think.

its a odd one for sure.

There is no vibration. I have tried to make it come on by drivng the car hard, punching the throttle, etc. It only comes on under normal cruising at speeds around 55+, and it only stays on for 10 seconds at a time.

well at this point i think you will have to go have it scanned, thats really the only way that the problem can be pin pointed.

Mine just randomly came on too. But mine is on all the time.... Might have to check out what scottydoggs said.

Listen to Scotty...he speaks from experience.. Listen to Scotty...............he's suggesting something free and easy to try.

My air bag comes on in cold weather less than 60 degrees. Had the code read and it was the front sensor. Replaced the sensor and same thing. Noticed that it would not come on if the car was warm when I restarted. So I must have a loose connection some where that is worse cold. Where is the module on a Bonneville?

Sure..pick a year I'm not familiar with.

hey 2000 SSEi.. where is the module? PS.. Call me back.
