Hello,
I replaced the complete headlight on f01 lci and doesn’t work. 
Ista says no communication with STML module and light doesn’t work. 
Anybody has steps how to code a used led adaptive headlight ?
The car has led from factory it’s not retrofit. 
Thank you.

Which module exactly because I have turn led module, tms module in the headlight

Check fuse’s. Happend to me twice that fuse was blown and that was the reason why i can’t connect with tms.

Thanks. Is there a fuse for tms or which fuse do I look for ?

I was just doing this last week. The brown wires are ground, so check for power with a DMM. Both the large and small red wires should have 12v power. There are at least 2 fuses that control this. If wiring checks out, try a different module. Injecting CAFD with E-sys was the easiest way to get things running

Thanks I’ll take a look. Do the red wires always have 12v or only with ignition on or headlight on ?
