Good afternoon

im sitting in the same boat did you guys get this right ?

im thinking of making plug and play harnesses if this fails

but want to get the coding done .

anyone to assist

Sameone know additional coding of bcm?
Done 74 and c2 al working no problems. But highbeam dont work. Only when dimlights are on.. not in 0 or parkinglights. Only when dimed lights are on. On a other forum i read about voltage must be set? Some say missing some bytes. )but witch ones..

When i push stalk to front, after 5 sec high beam error. Vcds show high beam open to plus on both sides.

Tried all options with bi xenon shutter, w/o shutter etc but stil same on highbeam..
