Anyone know why my car is throwing "2FA3

N54Society · 06-08-2016, 02:17 AM

I'm running a custom tune via MHD and occasionally go back to an OTS 91 Stage 2 map. I've interrupted the flash a couple times by accident by opening my door and then re-flashed to complete it.
I can't seem to get rid of this no matter how many times I've cleared DME codes and other module codes. Any idea what this means? I don't *think* it's effecting my car's performance but who knows.

MHD folks, how do I get rid of it?

Thanks

It's nothing to be worried bout. Can be toggled off in tuner pro.

it requires a coding of the dme to factory defaults with inpa, because you are now running a more recent software. That's something I need to add in MHD. Still, 100% benign.

Which parameters would need to be reset to default? Any idea when you'll have this feature added?

Thanks

It's just coding the DME to factory settings (which doesn't nothing, but stil a requirement) with winkfp. Sorry I can't give ETA.

INPA is for diagnostics and WinKFP is for flash reprogramming. Neither of those tools will code the DME.

Default code the DME (62BMO) with NCS-Expert using the SG_CODIEREN job. That will clear the 2FA3 code.

Help car won't crank after mhd flash

I'll have to try this out. Thank you!

If present, 2FA3 "coding missing" is now coded away on the fly when using MHD Read codes.

So the MHD automatically codes this now?

I have this and didn't know MHD was recently updated to code it out.

After clear codes it won't be there next time?

I saw that in the release notes and smiled. Thank you.

I haven't tried it yet but I think it fixes the issue on after hitting read codes and it shouldn't reappear.

Not after clear codes, but on the fly while doing read codes (which will be a 5s process to code it out).
In case it's still present, please drop me an email.

I'm getting a dme shadowing missing code, I tried to clear codes and still get this should I do a full write again. I know my battery was getting weak toward the end

Hi,

I'm running V7 Stage2+ and I'm seeing this code 2FA3.

Is this meant to be removed as part of a flash (auto-magically) or does it require further steps?

Cheers

Do MHD > read codes > clear DME codes with ignition on, engine off.
