Ok....i had the led drl harness from clstech on my 2014 when i noticed the pass lamp led characters flashing. I tried to diagnose....but nothing seemed to work. So i removed the harness and immediately started getting service adaptive headlamps. I also noticed when i get this notice...the bumper drl lights dont work. Ive even noticed them flickering and flashing. So i took to dealer and they diagnosed as the adaptive module being bad. So the new headlight came in today...got installed and still get the same service adaptive headlamps.

The DRL harness taps into 2 wires on each headlight harness.....should i replace these wires? I tried to.pinch them back together and taped over with electrical tape. Ive removed the negative on the battery to see if that clears the code. Any other advice?

When you replace the headlight , they need to calibrate them. I believe its a software process.

When my headlights where replaced for water intrusion I had the same issue.

Has the dealership hooked up the computer again to read the diagnostic code?
Where the positap connections were made, is it not just a small needle like hole in the wire?
 
#5 ·
No....the service adaptive lamps came in on way home.
Yes...its a small needle like hole...but they are very small wires. It seems like that would be enough to cause signal.loss pr whatever its called.

I'd let them get the code it's throwing now to be sure.

Everything seems to be working except the adaptive lamps turning. Hopefully its just a reprogram. Its cost me a small fortune.

yep...they noticed the damage to the wiring on both lamps and ask me how it happened. Karma is a bitch...so I don't lie.

Thye want to replace the wires on both harnesses if this don't work. That's why I asked.

Understood, sorry for the troubles. Keep me posted.

Hey Guys - I have same harness and noticed my adaptive headlamps (we are talking auto brights, yes?) no longer work. Thats why I logged on tonight. I Haven't noticed or checked for some of the other issues Scott has, but getting ready to leave at dealership for a laundry list of items (mostly minor, but side question - do either of you get a strange smell only during full acceleration) so wondering if prudent to remove harness?

I did check Settings>Lights>Adaptive brights was on. Was going to reset by holding down volume & Tune knobs but hate to loose my 4.2 0-60 run. (Yes- I could upload or download).

Just thought I would drop in on this. Will follow thread. Thanks fellas.

I first noticed some flashing on right side and the LED character inside the headlamps was flashing and then was off. So I removed the harness. Then I noticed the led drl bumper lights doing all sorts of craziness....off on...flashing etc. Finally I got a "service adaptive headlamps" on the dash. Adaptive headlamps is the self leveling and turning left to right of the lamps. I noticed when I would get this warning....the bumper led drls would not be on at all.

adaptive headlamps have nothing to do with the auto brights/dimming. That has worked the entire time for me.

Thanks for the prompt reply Scott. I didn't think so as the auto dimming should be relayed to a photocell issue or software, but thought I would ask. I did just go check Connells instructions on Google and saw there was something going on w/ March on builds (?) But shouldn't affect me...

Hi guys, mine just started to have a different problem with csl harshness now it only turn on the driver side (export). So I quickly removed it and all back to stock no problem. Then I thought a lose wire but all seems fine and doing the same thing. It powering the driver side light(export). It's been working perfectly until today on lunch time. Could the relay be overheating? On auto,off,parking light showing one one headlight on no drl. But switching the headlight on seems to be turning on the headlight and drl no problem.

Relay only activates to make the headlight ribbons go dim. If the relay failed both the ribbons would stay on bright. If you feel comfortable slicing open the main black bundle of wires right below the relay, you can separate them to see if the problem still exist. ( maybe a short has developed through the heat shrink used to cover the soldered connections)

If you're not comfortable troubleshooting, I highly recommend removing it and we can work on getting you a replacement.

Whtbox fixed his issue. I'll let him chime in, but it was a short inside the heat shrinked bundle of wires.

Scott did they pull the code again? I'm hoping it just needs the recalibration now. Also one of the Australian guys who was letting his sparky poke around last year messed some sensor up. Hopefully the headlight replacement was the right place to look.

Well as cls suggested, my problem was somewhere a shorted wire, not sure how it happened. Therefore, I split the wire up Cable management Electrical wiring Wire Electronics Technology
.

After this the drl start to come alive again as it should be. So I electrical tape it individually to prevent it from shorting each other out again. Will see how it goes if it'll do it again or not.

But this issue didn't damage any of my headlights and it perform as stock when I removed it completely. Also mine is the 2015 with the drl wire missing.

Yup.

I haven't had it back in yet! Im gonna call and ask them about a reprogram. BUT...I still notice m LED bumper lights going out at times. Only when I get the "service adaptive headlamps"....but not all the time. Its frustrating. I did notice the DRL fuse is loose in its spot. I would guess that is from the tap that was used. I replaced the fuse. Lets see if that helps.
 
#22 ·
Gotcha, I'm definitely here to help troubleshoot. And I'm sure the more eyes on it the better.

Had the reprogram done....it was a no go. Still got the "service adaptive headlamps"

The tech that usually works on my jeep.was out today...his father passed away. He is gonna call.me with the codes when he returns. Its definetely in the wiring. I guess im gonna have to spring for that now........ugh.

Folks...use caution when messing with the wiring in these jeeps.

So recalibration was no help. Not good.

You mentioned the adaptive module was what they said was bad... From my recollection of a previous issue with a member who had their "sparky" try to force the harness to work, the adaptive module was not apart of the headlight itself.

I'm not sure they replaced the right thing Scott. I'm interested to hear what the codes are they pull this time.

Secondly, although you are running out of items to troubleshoot, I think you will be wasting time replacing wiring. I'm no service tech or electrician, but I'm an electrical engineer by education/experience. The small insertion point on the wires should not have that much of an effect on the wires conductivity. If anything the can ensure the wire is not completely severed inside the insulation by soldering in a jumper piece of wire.

Again I'm not sure that the adaptive module is actually part of the headlight. That may be the issue.

I hate to see this happening to your vehicle with so many other kits out there running well. Maybe they aren't all running well... I urge anyone with issues to speak up so we can find a resolution.

Yes....the adaptive headlight module is located inside the pass lamp. The pass lamp has all the controls for leveling etc. Thats why the extra wiring going to that lamp. I wish you were here Connell. Im thinking about having someone replace the wire where the harness was connected. If u remember. ...i had two harnesses. I.didnt think it would be wise to connect the 2nd harness in the same spot....so I tapped in a different spot. The wires dont look that bad to me. I even used some electrical tape on them thinking maybe the circuit was open causing the fault.
 
#26 ·
Understood. Yeah if they are going to replace the wires completely maybe get some one to simply replace that section of wire as a first step.

Wish I was there too buddy, situation is really bothering me.
 
#28 ·
So far this looks like a one off freak incident. However I would use caution if you're not comfortable.

Still waiting in drivers headlight....then they will calivbratea dn program the new headlights together.

I installed mine last saturday, took a good 2 hrs to get it to work , I too kept getting the svc adaptive hlight warning , i disconnected the battery and warning cleared, another problem "I thought" I had was the bumper LEDs were not working, took me a while to realize they do not come on when E-brake is applied even if the Jeep is in drive

Scott, how long did you have the harness installed b4 this problem?
I'm thinking about removing this mod from my SRT, lol

Chris
I would remove it if you are concerned.

To the people that faced problems with this mod, can you answer the following :

1- did you install the harness yourself ?
2- did you install it with additional/pins wires
3- is your car built before or after March '13
4- is your car an Export

I'm trying to understand why the harness is causing problems for some people, yet many others I know have no problems at all.

I did the install myself, I bought my harness used from a forum member who sold his SRT, 8/13 build
After carefully reading instructions, it was an easy and clean install, however I had to uninstall and install about 3 times before it worked properly , my 2nd favorite mod after Gthaus, if I had to do it again I would , no regrets just a little concerned that's all . Overall great mod. Everything's working fine no warning lights or anything

If you have the harness and having issues feel free to reach out for troubleshooting assistance. Definitely here to help.

With that said, if you are uncomfortable with the mod, I wouldn't recommend getting the harness since people are having issues.

Scott I don't think the issue is in the headlight modules themselves. As I mentioned before a guy in Australia who did some tinkering on his own, messed something up that wasn't in the headlights.
