Scott, I know you are scared. Perhaps you should at least try one more time installing a new CLS harness and tap on the exact same hole from the first Positap (not creating another hole).

It may just what I'm experiencing, Once you tap you can't go back. Unless you get the wire completely repair or replace.

But it's all entirely your decision.

I read this quote from "CWgrizzwold"

I received CLSTech's first prototype DRL Harness and shortly after receipt I realized that the diode was installed backwards so I took the liberties of changing that by cutting it out of the harness and re-installing it with two butt splices. The added resistance those two butt splices added to my headlight circuit was enough to trigger the "Service Adaptive Headlamp System" error. I spoke with a tech at the dealership and he said the Jeep senses both voltage and current draw in the headlamp circuit and will error out if one of those exceeds the limit. I did not get the limits from him. However, the Jeep checks those constantly which is why the error may come and go. As long as the error is present the headlights will not turn with the steering wheel. Once the error disappears the headlights will turn again. I have since replaced my prototype harness with a "production" harness from CLSTech and have not had the adaptive headlight code return.

Keep in mind the wiring systems and monitoring that goes on is more than most expect. Any subtle change in voltage or current can skew the command the ECU is trying to provide. If it is enough it shuts itself down to prevent any further "damage" even though no physical damage may be present.

Just my two cents.

Re: headlight problem....led lights on bumper

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.

Mines the same way. I need to do this as i have no adaptive lamps at the moment.

Wish I could fly out... A car audio place could replace the wires I believe..

Re: headlight problem....led lights on bumper

Just a follow up on my repair work that I spoke about a few posts earlier...

I have been daily driving the SRT this week (both during day and night) and have had ZERO instances of the "Service Adaptive Headlight" message since I replaced the damaged sections of wires. Everything has worked as designed from the adaptive headlights at night to the DRLs using CLSTech's harness.

Any of you having the Service Adaptive Headlight message should take a good hard look at their tapped wires to ensure they didn't look like mine and replace any damaged sections. I used standard 18-22 gauge butt splices from Radio Shack and shrink tubed over the top and then retapped just below the splices for the DRL harness.
