MRS codes, help diagnosing and understanding

[Nate047]

Hey guys, I have recently got my car put back together (mostly) after sitting for a long time. I have also in the interim, removed and reinstalled a bunch of stuff, including the seats and steering wheel. I now have a bunch of MRS fault codes and I want to make sure I understand how this all works, and how to properly diagnose, clear and make sure everything is working.

The car has stock seats, stock steering wheel and airbag, and no airbags removed.

I have this Autel scan tool:

I do not INPA or any other diagnostic tools. TBH I’ve never really understood how these different kinds of codes can differ and why, the Autel scan tool spits out things that often seem weird or hard to interpret to my more knowledgeable friends when I ask about it. There’s probably an obvious explanation and I’d love to hear it. Very much not an area I'm good with.

Here are the fault codes I’m getting from my scan tool, maybe you guys can help explain and advise on what I can try before I start buying more stuff I don’t need.

If this is beyond my breadth (likely) I would also be curious if anyone in the LA/OC area can help me out with this, coding, etc...

Thanks for looking!

Bump, anyone?

I think those are restraint and airbag codes.
Do you have air bag light illuminated on the dash?

Typically those errors appear when airbag is removed with the battery still connected and won't clear on its own.

Not sure if the that Autel can clear airbag codes.

Im in OC and I have INPA and Bmw Scanner 1.4 (PA Soft).

What is the question? Did you clear them and they are all coming back?

Looks like they are all related to with the key on:

• Airbag being disconnected
• Seats disconnected

Clear faults?

Thank you, yea I do realize in hindsight that the battery was not disconnected when I did some it maybe all of these things. Mistakes were made. I had previously been able to clear MRS codes with this scan tool but it won’t clear these ones.

Yea I am trying to I guess at this point see if I can just clear the faults. Any other tools I can do this with aside from INPA?

The schwaben/foxwell tool works

[George Hill]

Yes, clear the faults, these are all normal that I would expect to see from a car being disassembled or worked on. I set these all the time, no "mistake" was made other than adding a step to get the light off.

If your Autel can read I would assume it can clear?

Thank you, yea the reader had worked previously to clear codes like this, but it keeps giving me errors now when I try. I’m borrowing a tool from a friend to try tonight, hoping I can make some progress.

Update: I borrowed a Foxwell scan tool from a friend and managed to clear the codes. It seems like they all went away except one, which is great, thank you guys. This one code keeps coming back though, and I had forgotten about this since the car was down for so long, but I knew about this way back in the cobweb filled parts of my mind from before, so it doesn't shock me to see it again.

Belt tensioner, front passenger. Just replace that part at this point? The code persists and it's definitely plugged in. But LMK if I should try something else before buying one.
