After months of tinkering with airbag..it's fixed.
 

This one was a doozie...I have always had a constant airbag light so years ago I removed the lightbulbs in the instrument panel. The dealership at the time could not figure out why my fuses were blowing. They were 5 hours into the job and didn't have a clue. So a few months ago I'd figure I would give it a try again myself. I replaced the CU the first time and it finally stopped my #8 fuse blowing so I could actually read the codes. The old CU had both safety sensors blown.
Once the CU was replaced I was getting #3, 14, 31 codes.
I then proceeded to replace the main harness...pulled out the carpet, glovebox, about 100 screws it seemed. Hooked everything up and got only the #3 and 31 codes.
I then replaced both front sensors...I thought #3 would be solved right? Nope. I checked the resistance and both sensors were infact good.
Code #31 took me to figure out what was wrong with #16 fuse. I checked voltage and found out the small green/yellow wire was bad from the body harness to the fusebox. I made a small jumper from that fuse to the main connector. Success, my airbag codes have all gone away and the light has disappeared.

I thought I would share incase anyone is struggling with airbag problems.

Many thanks to Redlightningsvx for assisting me with interpreting schematics and troubleshooting.:D

Wow what good timing, last night I did a search on air bags and got zipp, I also have the A B L on my "parts car", I have not really looked into it as I have zero experience with this stuff, but I was wondering where to start. The car has been in a L F collision but has been repared, although not well, I am thinking front sensors not replaced after the crash. After I swap the tranny I'll dive into that A B L Anyway thanks for the info and good work..........G

And here I was thinking the "Airbag" light had something to do with my wife *HEHE*

Haha funny.... :)

What year is your car gbianchi? I have an OBD I (pre 96) and I use the test connector provided to read the codes. That's the easiest way to figure out what is going on and to see if your sensors are faulty.

Yeah not too many people on the forum with airbag issues. I went elbows deep into this one.

Glad to hear we finally found out it was a stupid wire.:p

Yeah tell me about it...how long is our PM trail about 25 messages?:rolleyes:

Ok off to put the radio back in AGAIN!...LOL

Re: After months of tinkering with airbag..it's fixed.
 

I'd say more.lol Just happy this whole ordeal with airbags is over and you know ALL your bags are working properly now.

Re: After months of tinkering with airbag..it's fixed.
 

Agreed...next up are sway bar bushings and I see an oil leak near the cams ...ugh

Re: After months of tinkering with airbag..it's fixed.
 

Wow I wish I had time and a location to do all this... My airbag light has been on for 2,000 miles or so now. How long did it take you to do everything?

Re: After months of tinkering with airbag..it's fixed.
 

Well I had to work on mine in my apartment parking lot...LOL

I really don't know how long. I would say about 4 full months from the day I really started taking it apart. I took it apart originally..fixed what I thought was broken, then found out that wasn't the problem so I put it back together in frustration and left it alone for 2 months. Then recently wanted to get it fixed again.

Realistically I saved hundreds if not a few thousand dollars on doing it myself without having a tech or suby dealership do it. Airbag parts are very expensive if you have to buy new.

Car is 92 obd 1, what connector are you you referring to, thanks ........G

Re: After months of tinkering with airbag..it's fixed.
 

In the picture attached it's figure 6
A black 10-pin connector and you should have two black w/blue strip wires near it to plug into any of those pin terminals.
It's under the kickpanel fusebox.

Re: After months of tinkering with airbag..it's fixed.
 

So you are using the check engine connector to check codes on air bag light??
More info please, I just learned how to diagnose CELs for the engine!!! "NEWBE"
Thanks .........G

Re: After months of tinkering with airbag..it's fixed.
 

That plug is used to diagnose a lot of things including the airbag system.

Re: After months of tinkering with airbag..it's fixed.
 

Oh yeah I love that connector!
For airbag diagnostics stick one of the leads into the #9 terminal to read the codes.
To clear the codes plug one lead into #3 and one into #9
