BMW E46 330 ZHP SRS Airbag Issue

[danewilson77]

Just met up with Johnmadd....member here. OBTW....so awesome knowing someone from the site....wrench turner...and lives about 4 miles down the road.

Anyway....his SRS airbag light came in while driving. I read the code as Table 04.....with an "FO" code. The "FO" correlates to an "internal error" Anyone seen this one before because its knew to me.

I recommended that he do the "unplug the battery for 30 minutes" to try and reboot the system.

We will see how it turns out.

If anyone has any other idea's or insight.....that would be great.

I am going to post my history from my reader here...so you can see the most prevalent codes.

NOTE....there is an "FO" code below...and on a ZHP....very interesting. May be able to get a hold of this guy to see what he did to fix/clear the issue.

From what I've been able to dig up, it's a control unit fault.

Still digging...

I hope its not the airbag ecm, but that was the first thing that came to mind when that code was read.

Yeah-- really having a tough time finding any useful info for you. The only positive thing is that I keep reading that control unit failures are very rare...

Thanks for the help Dane, I hope I can help you someday in the future, and yes it is cool to know someone else from the site that loves bimmers as much as me just lives down the road. I noticed the 03 zhp on your list with the same code just a couple minutes ago, sure hope that dude responds.

I actually have piece 4 sitting on my computer right now. It looks plug and play to me...which I think would be worth a shot.....

Lets hope it isnt that control unit.....that I prolly threw out.

Thanks for your research, I always remember somebody that is helpful and friendly.I don't think a rare problem is really a positive thing though because there is less knowledge with something rare.

Try switching out the sensor I have above. Take us like 5 minutes.

I did read something about a 15$ harness with the yellow plug going bad, something about the old one builds up resistance over time.

Sure thing, man.

You've got DW. He's a problem solver extraordinaire. You'll get it worked out.
