For the last month or so, I've been getting this code, and all I've found on the forums on it was this, which means nothing to me. And only two instances of it!

2DC3 Control clamp 15
Error will not cause a warning light
Error is not currently present
Test conditions have been completed
Timeout

HELP!

Running a 2008 stock 335, 6MT, on 91 octane gas, with a Procede, on the latest map and firmware, on map 1 defaults.

Only issues I've had with the car lately have been really lean AFR's (17 to 20) during partial throttle acceleration (like 20-30%), especially when going up hills.

Pretty sure clamp 15 refers to switched 12v power....not sure what the error means though. Maybe check your ECU wires?

Hmmm. The closest codes to it are:

2D5A 11610 Control motor torque limitation
2DC3 11715 Control clamp 15
2DEC 11756 Power management, battery control
2DED 11757 Power management, standby current control

The two after it seem to be related to power, but I thought the way the codes work is if they're related to each other, they're very close in sequence? Like 11756 and 11757 which are related to power management.

I might check them all I guess as I need to do a test for Shiv anyway for him to figure out why I'm getting these crazy lean AFR's on partial throttle.

I'm very meticulous though and take my time when connecting it each time, so I doubt that's the issue.

I know from some other diagnostic software that "clamp 15" means either switched power or constant. I'm pretty sure it's the switched power. Don't ask me what it means in context of the code, but I am 100% sure it is related to power.

Loose wires from the ecu I think. Un-install the Cede and see if its still there.

Hmmm... saying it must be power related got me thinking of one thing. A few months ago, I installed a SmartTop module in my car (it adds extra functionality to how you use the convertible top). It has a known issue where on some cars, it can disrupt the signals between the various modules when the car is "asleep", and when you unlock the car, you can see a car on a lift symbol even. It is caused by having it connected to switched power, and the fix is to connect it to constant power.

It hadn't really created any issues for me so far, other than seeing this occasional symbol in the dash when I open the car door (and that comfort access doens't work on the trunk), so I haven't rewired it yet. But maybe this code is related to that. I've been running the Procede for over a year, and a few months ago was the first I started getting this code, right around the time when I installed the SmartTop.

Hope that's it...

I apologize for bringing this back up. I did a search on the code and this is the only post that has it. Were there any resolution to this issue?
I removed and reinstalled procede but still received the same code?

[Glowin]

In my case, it WAS related to the SmartTop causing power issues. I got it updated, and haven't had those codes again.

[s2k_335i]

I don't have SmartTop so I am still troubleshooting.

I have a Procede Rev3 and my car runs great but it throws following codes, too:

2D5A 11610 Control motor torque limitation
2DC3 11715 Control clamp 15
2DED 11757 Power management, standby current control
2E8D 11917 Intelligent battery sensor, signal transmission

Any ideas? Aside from the LCI tails and new Navi Professional system I hadn't installed any other aftermarket electrical equipments.

[NightStalker]

bump I'm having the error code coming up in my car and keeps draining my battery also...the transmission keeps making clicking noise and prevents the car from sleep

[lovcarrib]

Terminal R or terminal 15 were switched on for too long while the engine was off. The current consumption of the vehicle is then, depending on the equipment, 10-15 A. This discharges the battery very quickly. If possible, point out these facts to the customer.

I am getting these new codes on my 2008 e90 335xi recently. I was wondering if you were ever able to figure out what solved the problem for you?

I get these new codes as of today:
2DC3
2E8D

I have been getting 2DED for a few years now

A new code that popped up in the past couple months has been:
2E97 - This seems like an alternator code and I did change out my Voltage Regulator recently to a new one but the code remains still 🤷🏽*♂️

Any Ideas?

I too am getting the same codes 2DC3, 2E8D. I recently changed my MHD tune, and these codes popped up right after that(from having the accessories on too long..?). The reason I was changing my tune was because I put in PR coils.. but I am doubtful the coils have anything to do with these codes, and the car runs like a dream. I did have a lot of oil/debris in my alternator last year.. I'm wondering if it's finally on it's way out - I'm expecting it, to be completely honest. My battery has been solid, it lasts winter after winter in storage, connected the whole time, and it's original OEM. Might be the battery starting to go, I can't rule that out based on age alone. Anyways, in my case, I am definitely leaning to alternator.

Did you ever figure this out? I ask because I just used MHD to flash my DME for the first time ever (to Stage 1+, almost bone stock with fresh plugs and gaskets). I just went out and drove around for an hour or two, mostly around town but I did take the opportunity to put the tune to the test (holy s***, but that's irrelevant) and the car drove beautifully the entire time until I was on my way home. Just after going WOT briefly while passing on the highway, I got this code.

My alternator also recently had a bunch of contamination from an OFHG leak that was present when I bought the car. I was very thorough, and was meticulous as I could be when cleaning up the mess from that gasket leak as I replaced the gaskets, belt and pulleys (except the alternator's decoupler pulley), including spraying some electrical contact cleaner into the greasy parts of the alternator to try and clean it up as best I could. I knew there was a possibility this could introduce a problem where one didn't yet seem to exist, but weighed that against leaving the alternator soaked in oil and took my chances.

At the same time it threw the 2DC3, it also started throwing a code for misfires on cylinder 2. It's quite possible if not likely that's unrelated to my 2DC3, as the car just passed 105k miles on stock coils, and I just replaced plugs, so I might have something loose or whatever. Planning to troubleshoot later today. The misfires were the only codes still showing up after clearing them the first time.

Even more perplexing than the 2DC3 is the whole raft of arcane codes that fired along with it. And these, too, may be totally unrelated to the 2DC3, but I figure more info is better than less:

Perhaps relevant to the list of codes shown in that screenshot: I was getting a code a day or two ago that when I googled it, it sounded likely to be resulting from a dirty rear wheel speed sensor. I had planned to clean it off and see what happened, but the next time I started the car it was gone and hasn't shown up the last couple of days. No idea why I would be getting codes about steering wheel position or any of that, though.🤷

Any advice or input about some or all of these codes would be appreciated, but since the thread is specific to 2DC3 it may be best to stick to that, and I will do some research on the rest separately.

I know this is old but did you ever find out what this was. I’m having the same issue as you. Please let me know thanks
