Update for those of you with the Service Adaptive Headlights message...
I have been fighting this message off and on for a few months now. When it initially happened I split the harness up below the relay and shrinkwrapped the wires individually and that seemed to help for awhile...until recently.
Over the last few months I would get the message on every startup. Sometimes it would go away after a few minutes and other times it would stay on the entire time. So I ordered another harness from CLSTech to do a clean swap as I figured my splitting of the wires or messing with the harness caused some undue resistance that put the adaptive headlight system over the limit.
So, before installing the new harness I took a quick look at my posi-tap locations to ensure I had a good tap and realized I had turned the tapped wires on the passenger side headlight into a bit of Swiss cheese.
I knew this couldn't be helping the situation so I disconnected the harness completely and fired up the Jeep and still got the Service Adaptive Headlamps message. So, the issue was confirmed to be with the factory headlight harness and the "damage" I had done to it.
So I decided to remove the pierced sections of the two wires and use butt splices to join the good sections of wire back together again and added shrink tubing over the top.
At this time I hadn't done anything to the driver's side outside of removing the DRL harness and posi-tap. I plugged the connectors back into both headlights and fired up the Jeep and waited several minutes for the message to appear and it never did.
From there I retapped the two wires below my butt splices with extra care to ensure a good tap and reused the pierced hole on the driver's side wire to reconnect the posi-tap and harness.
When I fired up the Jeep the DRL harness worked as designed and I have yet to get the Service Adaptive Headlamp message again.
So Forum members out there with the same message take a good look at your tapped wires to ensure they don't look like mine and even if you think you have a good tap you might want to take a close look at or through the tapped hole and ensure you haven't damaged the wire. When in doubt cut out the tapped section of wire like I did and splice back together. The rejoining of the cut wire sections is not easy as there isn't a lot of free play in the headlight harness to allow you to pull it up and above the engine to make the splicing any easier. Take your time and ensure a good splice.
