Default What are these codes for?

I'm using pasoft to read DME codes and not too sure what these are

02 [ 002 ] idle actuator locking winding

1D [ 029 ] idle-sp control valve NC winding

I thought they were related to the iacv and I replaced that and still throws the codes.

This is an s54 swap into a 2000 E46 wagon. I looked up the DME Penthouse between ms43 and Mss54 and they have the same pen assignments for that sensor.

Maybe it's for something else?

Don't worry about the other codes I have the maf disconnected because I was replacing the starter.

Just to confirm what you've not mentioned, but maybe figured out - for your other errors - the DMTL and the brake light switch - they DO both need to be re-pinned from MS43/5 for sure.

Let me know if you need the pin info for those, I just debugged an M3T build wiring job recently and should have the info handy.

Neither of those has anything to do with the MAF being disconnected, so not sure what you mean there... but any way...

Those indeed are ICV errors. You can confirm the text vs "official BMW language" here, but it doesn't give you much more at all:
http://www.chitownm.com/forums/showthread.php?p=61655

Basically the "opening" and "closing" coils are both throwing errors, you can see from the diagram that it is opposite ends of the same coil so the DME can flutter it open/shut/open/shut. Sort of a push-pull situation.

Are you sure you don't have a connector swapped? There's something with a similar connector down there, I forget what. Other than that, triple-check your continuity on the pins (duh obvious I know...) but its not a complicated circuit, just those 2 pins plus the current supply from Fuse 2. (is fuse 2 ok?)

would love the pinouts for DTML and Brake light switch if you have them. i didnt see a difference but my eyes may have been playing tricks on me when comparing pinouts.

I will check the fuse #2

i checked the connector just to be sure and it should be the right one. it has 2 pins in the plug despite the IACV actually having 3 pins in the unit itself.

i tried looking around to see if anything else was plugged in incorrectly and nothing else would fit. seems all the plugs have different slots in them to allow them to only connect to the proper sensor?

I will also check the continuity as well. thank you for the heads up and confirmation.


I reset adaptations on the DME due to a fluctuating idle... and now the idle is very high... around 1200 with OUT AC on... and around 950-100 with AC on.


im hoping its related to the IACV and once I fix that it goes to normal because i cant figure out anything else to resolve a high idle.

Default Re: What are these codes for?

Here's my notes from that job... This should do it. The exhaust flap comment is for an M56 car, not sure if your recipient car has that or not...

The one thing to note is that the DMTL comes in 2 versions - heated and non-heated. The pins below are for a 4-wire heated DMTL.

Code:
6A Brake switch 

Move DME Pin 28, connector X60004 -> DME Pin 34, connector X60004  (brown w/ gray)
DME Pin 24 on connector X60004 can be removed/taped up (black w/ red), or left as-is

7F DMTL 

Move wire on Pin 2 (black w/ red) , connector X60004 to Pin 18 of same connector.  
Existing pin 18 wire goes to deleted exhaust flap solenoid, can be taped back.

Almost certainly the idle is due to it not having idle control.

I suspect there's a 'fallback' function in the DME where it controls idle w/ the DBW ITB's if it finds there is an ICV error, and you're in 'ICV failsafe mode' now.

See the wiring diagram I linked above - the IACV absolutely needs 3 wires - 2 to the DME and one from power. Look closer for a swapped wire.

Welp stupid me had the alternator plug plugged into the iacv in the iacv plug plug into the alternator. Swap them in error codes are gone for that.

LOL awesome! I love when things get fixed easily.

M3T's are cool too. Good luck w getting it finished. Post back how it goes.

I swapped that pin like you said for the brake light switch and that error code is now gone. There was already a black wire with a green stripe in that pin from when I followed the kassel performance wiring diagram which obviously is wrong now that I see it. I left at wire taped off check my codes and I used to throw a dtml code and now I don't get that code anymore. It comes back then I'm just going to suppress that DTC in the hex.

Thank you very much for all your help

Nice. Yeah. My guys ran into badinfo from Kassel too. That's why I had to chase down the right fixes. .

Dont kill DTC's unless you absolutely have to, and in these cases it's def unnecessary. DMTL will totally work fine if you get it all wired right...
