Light problem, blinking led (SMC, ALC?)
Hello all
I noticed that the green led was blinking near the light switch. I turned my lights off and again on, and the led stopped blinking for a while, but then blinked again. I found out that it could be the stepper motor or a module. SMC or ALC? I don't know which one. I tried to go into the module via NCSexpert (LSMC and RSMC), but I got an error: could not connect to ECU or something like that.
The lights are not leveling, they are straight ahead. But in what situation will the lights level? And is there a way how I can test the leveling of each headlight? I also opened the SMC module at the bottom of the headlight, but there was no sign of dirt or something like that. Also I saw another little cable that goes into the headlight (see attachment). Can also someone tell me for what that tiny cable is for?
Hope someone can help me! thanks

Small cable/jack is for level motor.

Hi
Did you check the control units underneath the headlights ? , dismount them and see for wather in the connectors , often seen that moister have made the connectors bad , sometime cleaning the connectors can "save" the units
The big one is the starter box for the Xenon , and the small one is the ALC box
