Helm manual shows PWM source in schematics, but I didn't get a chance to look for details for operation modes. Don't know why they just couldn't use simple, negative switched, relay designs. Easier just to convert DRLs to mechanical relays with 12v source.
When I took my car in for warranty work, work order sheet cited BCM log messages due to customer replacing LED bulbs, not related to warranty problem. I wonder if they used PWM to monitor DRL functionality.
Got my replacements and so far, so good.

A fuse was not added to the wired harness to reduce cost to the end user, it isn't really necessary since you are feeding an LED light. We had one on our wireless harnesses due to the fact we were powering a remote control box.
