E39 LCM III replacement

Reint97 · 01-21-2025, 10:02 AM

Hi, i have a little problem regarding LCM (atleast i think it's the issue).

Problem: Turn signals, high beams, hazard lights, both fog lights not showing up on instrument cluster, outside everything works. Reversing lights not coming on when in reverse (Manual gearbox). Tried swapping around LCM's with exact same part number as the old LCM, with that nothing worked besides hazard lights, not on IC or outside. Shouldn't the "new" used LCM work even when not coded or is it bricked. Any ideas?

Hey man! You should code your LCM due to your ZCS аnd VIN fisrt. No matter if you have installed this ecu with the same part number as your original. You can do it with NCS Expert or with Tool32.
