ILS Intelligent Lighting - 2023 GLS 450 - alignment? review - specs?
For most ECE cars, it is available if your light is Multibeam version (SA642 or SA641).
For USA, there is only SA640, and SA608(IHC, High Beam Assist).
so if you want to know whether your car can be coded the ILS+ or IHC+, basically check you have code 640 and 608, if yes, then can do coding to turn 628 on.
if you have 631/632 and 608, then no way to code 628, as the light hardware has not such feature.
For digital light: if your car has code 316+608, then can do ILS+ / IHC+.
cheers!

High chance the light housing hardware issue.
