Help with code

Tacn It · 08-18-2011, 08:52 PM

Hi all, hoping to get some help, im running JB4 on my car with dp's. I have been running the JB4 with the auto clear function on to take care of the cat lees dp's . It has been running great for 6 months. Today on the drive home the half engine light came on(limp) i was less than a few mins away from my house, when i pulled up it cleared. i checked it with my BT tool and there was only one code left 2FA3. I have not found much info on this code. I tried to disconnect the battery to reset and that did not work, tried to clear with the BT tool and that did not work. Drove it around after and it seems like it is still in limp mode but no half engine light. Don't know what the full codes were b/c of the auto clearing function. Please any direction would be great help Thanks

Why don't you turn the Auto Clear function off so you can pull ALL the codes? Also, I thought the JB4 has code clearing functions(manually clearing codes, not auto clear), like the Procede?

Doesn't the JB4 also have a O2 modifier function like the Procede as well?

Ya i was thinking of turning off the auto clear function but was figuring i would get a cat code before i even got the other codes, so thats why i was tring to get a direction from the 2FA3 code. It is a true auto clear not manual clearing and from what i understand the auto clear function is o2 modifier for JB4.Thanks cstmx ryder.

It doesn't hurt to see what codes you car will throw....Regardless if the codes came before or after the one you're looking for....

IMO, it's not good to just ignore/erase the codes just because you can....

bryce · 08-19-2011, 08:27 AM

that's odd you're getting that code....the 2FA3 code is the one that shows up when you have the Cobb Accessport installed. it has something to do with an unknown software running on the DME.

Tacn It · 08-22-2011, 06:20 PM

how do i reset this code?just turn off tune and wait to reset ? anyone have any info on this code.thanks

bryce · 08-23-2011, 08:44 AM

is your sig accurate? It could likely be from running a jb4 on top of a dinan stg 2 tune. I wouldn't stack tunes like that!

Tacn It · 08-23-2011, 10:35 AM

there is alot of other people with this set up and it has been running great for months.

cstmx_ryder · 08-23-2011, 11:05 AM

Uhhhhh really? Like who? I've never heard of stacking a JB4 on top of any other tunes.....A JB , yes, but certainly not a JB4. As JB works differently than a JB4.

You should probably remove either one of the two tunes IMO.

I meant JB plus, the 'plus' symbols won't show up when posting via iPhone lol.

Tacn It · 08-23-2011, 02:41 PM

There were several post about running the dinain with jb4 (The JB4 can be run over the Dinan no problem as it targets boost absolutely so the JB4 will just overide the boost targets. YOu should notice a HUGE improvement especially in the upper RPM bands. Map switching is done on the fly, just your map0 now will be Dinan and not stock. Mike@N54.com) been talking to Terry from burger tuning about the problem. After turning off the JB4 and turning off the auto clear these are the codes coming up.
2FA3 - CODE MISSING
2FDB- Short circuit or signal interrupt
30FF- exhaust fume turbo charger low side
What i have read and what Terry says about the 30FF code is a boost leak, so im looking into that now but we are stumped by the 2FA3 code. Even with the JB4 off the code has not reset.

tibra1 · 08-23-2011, 02:46 PM

This is what I have from my list of BMW error codes.

2FA3 HO-proc.failure, coding error

There is a thread about it here as well..seems like it has to do w Dinan
