Marv17 - i don t remember, i swapped everything that was missing on my board. follow also the lines from the LEDs, you might find other parts you are missing

Has anyone else had issues adding the LDM to their car?

ACC shows up fine on the module tree, but the LDM is not showing up, I verified wakeup signal voltage and that it has power coming from my fuse tap. CAN wires are connected with PT-CAN high and PT-CAN low being connected properly. I'm using the terminal 15 wakeup signal for all modules but it seems like people have also had success using the dedicated ACC wakeup signal. I tried both and it still doesn't show up, not that I can see how it makes a difference swapping wakeup lines.
I ordered a new LDM to test with since they're cheap but I was wondering if these modules fail commonly or if there's something I did wrong here. Considering I wired up the radar properly I can't see how I did anything wrong here after checking 100x and I'm assuming I just got a dead module.

[Leucosticte]

Tried with a new LDM and my car still doesn't recognize it.
Does anyone else have any ideas?

[dumitru.o]

do you have the latest version of junction box? are you sure it s wired correctly? can and 15WUP?

just follow the diagrams, nothing else

100% sure it's wired correctly. I used a CAN to USB adapter I had and I'm able to receive CAN data from my wiring.

What junction box rev do I need? I did try a junction box I had lying around from when I was building a test bench but I had no success with it. The junction box was from May 2007 and my car was built in September 2006.

[dumitru.o]

That is old , you don t have the proper junction box

[Leucosticte]

Do you know which one I need then? RealOEM only says that junction boxes up to 09/2007 are compatible with my car. So it seems like if I get one later than that then I'll have to start rewiring things.

It does not make sense to me that you could order a 2006 E90 with ACC but my JBE does not support it despite being newer.

[dumitru.o]

realoem story is old, i won t explain it now

get M junction box

you might need to change more parts on the car and get to the new type of junction box instead of the old typa junction box

[Leucosticte]

I'll start looking for an M junction box then, they're cheap so I don't mind buying it to test with.

It looks like the wiring changes are limited to one wire to the OBD2 port to get it to communicate over D-CAN.

I am still confused as to why I have to put a newer junction box in my car when I haven't seen it mentioned in this thread. Nickco (the OP) had a 2006 330i that probably had a junction box from 2005. I have one from 2007, why is mine too old but not his?

I am just curious as to the reason mine is incompatible when ACC was an option on E9X since 2005 and LDMs were on E9X cars since 2005.

[Leucosticte]

An update on this:

I got a K-Line master JBE (says KL on it) and I installed it, the car works properly but I have no communications via OBD.

I thought the whole point of getting a "KL" JBE was to avoid rewiring, but it seems that I have to do it anyway, I will do it and report back.

Hello everyone,is there any advice how to add acc to a 328i lci 2012?does such a set even exist?

Hi Leucosticte,

I'm facing a similar issue.
My ride is an early 2006 E87 130i with normal CC ($540) and DSC MK60. I added an E92 Radar(6316777883) + SZL from one donor car, and LDM(6774206) from another E90 and a 335i High KOMBI. I used ISTA+ schemes as source: PT-CAN is coming from JBBF X14271 Pin 5-6, then I made 4 way junction and connected LDM, ACC and FRM (as preparation for AHL).
Wake up signals are taken from CAS 18-19.
I used two new fuses F9-F10 for ACC and LDM (this saved my ass for now).

First I installed and coded the stalk with standard settings, it is working great even the +-10km/h click is functional. The KOMBI is also working with $540 simply I have no visual feedback for the set speed, same as with the original dash.
Once I changed VO/FA from $540 to $541 and coded DSC, KOMBI, CAS, I received lots of errors:
C90B, CD87, CD8F, 2DC3, D17E
ISTA+ 4.31.40 is listing ACC, but not the LDM. The dash self-test at start lights up the car sign yellow and red, but that's about it.

I'm pretty confident about my cabling, but not my software. I couldn't write FA to FRM, because I receive an error (COAPI-2060 A_PL2FRX). I tried to set VIN for ACC with WinKFP, that also resulted in a SECURITY_ACCESS_DENIED error, but only after it went to 100%, which tells me the communication is working with that module therefore, the PT-CAN should also be functional (Though coding the ACC2 with NCSExpert is IFH-0009 No response.)
If I remove the fuses of the new modules and code back $540, at least I can revert to stock without any errors.
I gave a try then to the $544, only with the LDM fuse, also PT communication errors, but at least in the CCC I got a warning that the CC is not working and not the error that the whole DSC is bust.
iI also tried to change VO temporarly to E90 and E92 (even with build date to LCI), LDM doesn't show up in NCSExpert.
I was wondering if the DSC is the master in our case and LDM is just a submodule, or DSC is not compatible (but in that case others got another sensor plausability error if I'm not mistaken).

Next I'll try another installation of Standard tools, to see whether anything is different.
I hope together we can figure out what is off with our setups.

Ps.: someone mentioned coding LDM worked flawless with Pro Tool, but not with ncsexpert.

Hey,

Your symptoms seem a little different from mine.

For the LDM, is it red on the module tree or does it not show up at all? If it does not show up at all on the module tree then that indicates a problem with your VO. However, if it's on the bus and communicating properly then it will show up regardless of whether it's properly coded or not. Did you also write your VO to the CAS?

When I set my VIN on the ACC module via WinKFP I had no problems. So I'm not sure how to help with that, I think I've had that error on some other module but I can't remember the way I fixed the issue.

Anyway, your ACC module might be in the programming abort state which is why it won't talk to NCS, verify this in INPA/ISTA.

If the VO is coded properly, the LDM should show up in NCS even if the car can't communicate with it. You should double check your VO. In my case, my LDM shows up in NCS but I can't communicate with it. It also shows up in ISTA and is red. This is the issue that I've been trying to fix. I ordered the pins to create a wire to add KCAN to my OBD port, when they come in I will update the thread again.

I think that you need to figure out why you can't write your FA to the FRM first and why you're not able to change the ACC VIN, then go from there.

f series or e-series ?
there were no aftermarket kit for any bmw, because this system is very critical from regulator standpoing
but people did hundreds of the such retrofit to e and f series, collecting parts from junkyard and/or ebay

[weider91]

Hi guys I've just finished retrofit my 335d with ACC, everything is working well, but I have a question, is it possible to retrofit original acc into acc stop and go like e60?

[Rupppi]

I'm one step further after you pointed out the VO issue regarding the LDM.
As I have a different platform (E87 1 Series) just adding the 541 to the VO makes only the ACC appear. You can tell many ways NCSExpert what it should see and for me I had also to change the car, so the LDM appears. Practically I had to change the chassis to E90_ instead of E87_ plus remove the *UF91 and replace it with *VB31 (330i 2006). This is valid for the NCSExpert session if you don't write it to CAS/FRM, but it will be used for the coding. Unfortunately I couldn't code the LDM as it didn't answer and I still receive IFH-0009 from ACC2.
I might give a try to code CAS and JBBF first, because they might not receive the wakeup/pt-can as they're not present with the current setup.

ps.: FRM write issue was just lack of knowledge, that module needs ignition to work.

Sorry,E93 2012 lci
I know it's nor aftermarket.I have E93 2012 not Xi,just Rwd,I know people can make it for fed but for rwd didn't see,that's why I am asking

for e-series the kit is same for rwd and fwd
the only requirement is 6 cyl engine dsc or 4wd dsc

See what shows up on the module tree in ISTA/Status Request on INPA now that you're at this point.

Anyone have a source for an ACC Radar Sensor? $$

After some detour (retrofitting $470) to test my tools, some further baby steps.
I have now both modules in the tree in ISTA+ with writing the VO to CAS.

CAS, KOMBI and ACC are coded, DSC and LDM are failing with VB31 chassis, but I had only one shot before running out of battery (I couldn't even check for codes, not that it would much sense at this point).

Doesn't yours have the lens heating error? This can be coded out.
