The LCM is behind the headlight switch.

I get the same error message, and the sides work fine with the directionals. I may open them and dielectric grease the connections in hopes of a cure. I expect they are originals and covers have never been opened. I occasionally have a similar issue with the license plate bulbs.

The LCM is located in the right passenger footwell behind the kick panel on the exterior side.

Thanks!

Hmmm...interesting part is the "Replacement lightning".

Right now the left side angel eyes ="Front Parking Light" is out. That's why the left side-marker is on ...and the right side side-marker is NOT, because right side angel eyes are functioning. I guess.
I have the burned angel eyes bulb in my coat jacket waiting to be replaced. So I suppose all is cool after I replace that bulb. Haha. So better first replace the angel eyes and see what happens with the side marker before I start tearing the LCM apart :)

Thanks again for this information!

Edit: Because of this "dimming function" the side-marker gave out only little over 10 volts. In normal function without dimming it would be 12 volts.

Yeah, totally.

New bulbs at angel eyes fixed the problem where neither of the side-markers were never supposed to be on. :)

Thank you Qsilver for the document.
