3.0d, New AHL - does it need coding? And how?

Tried like you , to code and have the same error

Thank you

Honestly I don’t know. At first I was getting error for both, L and R. Than at some point I managed to code one, but the other one was throwing errors. And than, a few days ago I managed to code the other one. I assume that the problem is either with the version of NCSExpert or crappy cable.

Before I coded the other one I was playing with AHL module in INPA, maybe that helped somehow to establish communication.

P.S. I assume that you know that you need to have the lights on auto

Yes the lights are on auto. Don't know why i cannot code. The left headlight is max to left now moved ...

Hi, I'm having exactly the same problem with my e46 right now.

The green LED next to the light switch started flashing, I sent the AHL driver for regeneration, installed it and I could get to it in ISTA but the LED was still flashing, I did diagnostics with ISTA (moving the lamps using the menu) and the left lamp worked great, the right one not at all. I purchased and installed a new SMC module for the right lamp. The LED began to glow steadily, I can force the lamp to move with ISTA, but a new problem has arisen ... The lamp moved to the left and got stuck. What's worse, I can't code the LSMC and RSMC drivers with NCS Expert because I get the exact same error as you: ALC_DS2 COAPI.

How did you manage to code these drivers, what exactly did you change?

As for the management of the lamps and the fact that they shine too high for you.

- A) check in ISTA (or in INPA, although I do not know if there is such a reading) what the readings from the xenon leveling sensors look like, one in the right front wheel arch, the other in the rear left one. They are responsible for the fact that the car knows how to set the lamps up and down. It is enough that when replacing stabilizers or swingarms someone broke them and they will show nonsense. The reading allows you to see how they work, usually the maximum tilt when it gives the lift is over 4.00V, when I stand on an almost flat reading gives about ~ 2.5V, you can check how they behave with the reading on and how someone will press you forward and rear of the car - it should change slightly. And there is also one more thing - you should be able to manually set lamps just by wrench (up-down) its classic way to regulate.

- B) with INPA, from what I remember, you can set dynamic xenon, I don't remember if it's up or down or just right-left, but where there will be manual setting, right-left will also be vertical, go to Adaptive Headlights and look for Manually options.

- C) Running the reference run in ISTA while playing with them should set them in different ways but at the end they should return to the neutral position (if they don't do this then something is wrong, but here I refer you to point A first)


I'm currently struggling with the fact that I can't get to a single module in NCS EXPERT, even though the left lamp works perfectly ... Could you remember what exactly you did?

And as for the second person in the subject, my lamps are also currently stuck (the right lamp is as far to the right as possible) but I'm going to disassemble the lamp, unfortunately, to see what happened, although I will give the coding and cleaning the plug a chance if I come up with something)


Communication on the forum can be difficult because I'm from Poland and I don't know what country this forum is from so the time difference can be significant

Something else from me, tomorrow I will remove the insulation from the SMC beam for the lamp, I don't like that I tried to move one and the other was also doing something. And in general, when coding, it can also be important, so it's worth taking a look if there is no bare copper under your insulation and the cables are touching. Also I've noticed something important - there is no way to code one of LSMC or RSMC when other one is not communicating well. When we want to code one of them, programs always check communication to both.

Have you mount original SMC or aftermarket one ? I know this E53 when he pluged the aftermarket SMC the left projector moved to max LEFT and there is it even now. Probably is problem that the SMC isn't original...

[kruczek]

Aftermarket new, for sure we should code them using NCS EXPERT but for now I am not able to...

[kruczek]

Can you add me on whatsapp ? I will send that to you on private message here, maybe we figure it out something

yo bro, i fixed it. This new SMC module is worth nothing, I can't code it. I put the SMC from the working lamp into the one that moved my lens to the maximum right and fixed it for me and it is correctly positioned. The problem is this new SMC, buy a workig used one and you will be happy as me.

Admittedly, I first connected the lamps right to left, left to right so as to exclude cables problem, and only then I also changed the module SMC, but it turned out that it was him and the lamp worked correctly!

In my case I did so.

1. I connected the right headlight to the wiring of the left one
2. I connected the left headlights to the wiring of the right one
I don't know if points 1 and 2 are necessary, I connected them because I had no idea
3. I put the original driver from the second lamp into the shifted lamp, which I know works
4. Ignition
5. Lights on auto mode
6. The lamp moved on its own and straightened itself (I did it a couple of times and it worked every time)

But it turned out that this new module sucks, I just order a used one.

I'm glad you managed to code that other SMC. I got two original ones from BMW in Germany, I managed to code them, when I turn on lights, they move down and up, but the lights are still pointed up.
I'm almost sure now I have to set them manually 😬😬

Alexxxa as I said:
