Was this ever sorted out? I have the same issue. I made an in depth video on the conversion from halogen to LED but can't post it yet since the DRLs aren't working. Any insight would be appreciated.
I've done the swap, routed and re pinned the BCM connectors, and done forscan changes. Everything is working except my DRL light bars on the headlights and fog lights.. any idea how I can get them to work? All the DRL options in Forscan are enabled so I'm at a dead end.
