Hate to resurrect an ancient thread, but did anybody ever find a solid solution for this?
My 2012 JK 2dr has been doing this off an on for about six months. Same symptoms: light show, speedometer jumping, headlights flicker. Error code C2101. Twice the dealership has said there was corrosion on ground G107 and claimed that it should be fixed after they cleaned it. Not sure I buy that answer.
No lift (yet, anyway... the parts are ordered and on their way.) I do have a CB radio & winch, but the dealership made no indication that they are in any way related to this issue. I've checked both their connections and neither of them is loose.
Getting irritated, though. So, anybody finally get this issue resolved on their JK?

a) fire up the vehicle. Check for light show. If not present, you're finished and congrats. If present, go to b.
b) Completely remove the aux lights and their entire install. And I mean everything.
c) fire up vehicle. If light show present, your aux lights weren't the problem, take it to the dealer. If light show not present, it's your aux light install.
d) contact aux light mfg customer care line and see if the techs are aware of the problem. If so, have them send updated install instructions with any necessary parts. If not, get your aux lights installed by a paid professional. Or just leave them off the vehicle and alone.
Hope this helps.

|ejkstar||I have been dealing with the ight show for about a year. I installed a winch and some lights and thought that might be it. I disconnected the lights and put a marine battery disconnect on the positive winch side and the battery. The lights still continue. I was told the AEV procal programmer will remove the problem. I was told the problem is caused by the lift kit leveling out the jeep and the larger tires. I am on day 2 of the Pro Cal and the lights are back. Like you, Mladore, the dealer said everyone on the forum are whackos. So first let me say, Hi, fellow whackos. Any other ideas on what the fix might be?|

|mladore93||That sounds great. Glad you got that problem taken care of. As myself, after my dealer kept telling me no no no, and with the lack of other dealerships around my, the closest being about an hour away, i decided to disconnect my lights. Driving around for 2 weeks with the lights disconnected, the problem stopped. Yesterday i hooked them back up and i wonder if it happens again. I dont want to go back to that dealer, because i might get "I TOLD YOU SO" look from the service manager, who is a real a******! If it is the lights causing this issue, could it be a bad relay? These are KC Lights.|

Just an update. I went to a new dealership yesterday for a scheduled oil change and assistance with my ABS , traction control flashing issue. The dealer ran the diagnostic and found a code for a bad "stop light switch". This switch was causing a short in the system. He ordered a new one from the dealer I no longer go to and replaced it. He test drove the Jeep and ran it again for codes and found all clear. He also fixed my battery connection for my SPOD hook up. He said the cables to the battery looked loose and wanted to make sure all was tight. They performed all this for $29.00. I was real happy how it turned out , they now have a customer for life. Ps_in speaking to the service manager all of the techs and himself drive JK's , they really seemed right on the money with my Jeep and will quote me a price for the 3" lift I am looking to install this spring.

|chrisfp88||Ok I figured out my problem and I'm an idiot for not looking sooner. My positive cable of my winch pulled out from the solder less ring connector where it attaches to the battery so it was grounding out as I hit bumps driving down the road. oh well problem solved.|

Any luck on trying to get rid of it?
Im going to try the idea of bringing it to the dealer and having them spray the water, but since they put a note in my file saying aftermarket electronic's installed everything that happens they will blame on that.

|chrisfp88||I have this too.|

|mladore93||Got the truck back. The code was C2101. I disconnected my lights for now, and wait for it to happen again, then straight back to the dealer to prove them wrong!|

|dukedallas||Can you try a different dealership? ... I would be scared to continue to use a dealership that gives you a line of "BS" because they are too friggin lazy to actually diagnose the problem correctly. And if you were out of warranty you VERY well damn know they'd have their greedy paws open charging you $100 plus /hr diagnostic fee etc!|

This has nothing to do with your lights set up. I have the very same problem with my 2012 Arctic. I do not have any lights or addtional electrical equipment on my jeep and I experience the very same issues you are facing. The dealership told me the code came up as electrical surge , I asked for the fix and they said we have no idea what it is. No repair or solution. I posted on this forum for help and was given great advise , the problem is the speed sensor. When one of wheels on my jeep got wet from a heavy rain I had this "light show" happen every 10 to 15 minutes of my commute. I now have it during normal dry driving coniditions. I plan on pressing the dealer for a sensor diagnostic on my next service visit. The forum member told me to advise the dealer to use a spray bottle and wet each speed sensor and check for the alert sounds easy , but I will need to push my lazy dealership service people into helping straigten this out. Good Luck to you!

|mladore93||Once i get it back from the dealer ill just pull out the 2 external fuses from my lights, run it again, and if it hits, bring it right back to the dealer and demand them to fix it! Im doomed...|

|Phaedrus||This happened to me. Turned out to be a loose battery connection.|

|mladore93||Sorry about that, its a 4 door sport|

|kramer2k||I remember reading about a few remote cases of this happening to other Jeepers. IIRC, the cause was a short in the circuitry behind the instrument panel.|

2012 JK Dash Light Show!
Hey All, this is my first post to the forum so excuse me if i sound like a newby. The past 2 weeks, i have been getting a light show in my dash. What happens is the Brake Light, ABS Light, Traction Control, and the Hill Descent Time Icons all Flash for a second or 2, as well as a chime(like the one you hear for a seatbelt) then my speedometer (Not RPM's) will go down to 0, then back up to normal speed. This is all happening with no effect on performance whatsoever. So, i brought it to the stealership, and they ran some tests, and the only code they pulled up, was a code for battery strain. Sorry but i forgot the code number that they gave me. They said that my aftermarket lights, which is a set of KC Slimlite 120Watt and a Set of KC Slimlite 100 Watt, wired up using their harness, connected into the battery, not even near the jeeps harness or electrical, just to be safe. So the dealership said that could be the cause of this. I am really not sure, this is my first new vehicle, previously owning a 95 cherokee. Could the cold weather (NY) and the strain from my lights cause the dash and computer to think there is a short in the system, hence the flashing and chimes?
