|ohioviper||Unless something goes terribly wrong it is perfectly safe to jump start another car from your JK without any damage.|

|HAFICON||Well I can certainly understanding trying to help someone, But no good deed goes left un punished that is how I see it. If I were running a Dual battery set and could Isolate one battery then I would have no problem jumping someone. Other wise they can call somebody, I aint AAA, hell I dropped out of high school cause I was FFF *L*|

2. If you first reported this same problem under warranty, and Chrysler has not yet been able to fix it so it stays fixed, I would certainly expect it to be covered. I wouldn't think they can just "run out the clock" on your warranty on a repeating issue like yours.

|jk'n||An update: I have been on vacation for the last two weeks so it was difficult to get onto the internet. I was without my jeep for about 4 days. Here is what had happened. Before my vacation, my sway bar light began flashing occasionally. I'm on my third sway bar disconnect unit under warranty and most likely, this time, it is on my dime.....so I ignored the light. It would come and go just like the last two times. The first time, the battery began going dead after a while and then it was replaced. The second time when the light started flashing, I brought it back to the dealer and they replaced it without hesitation. This time I was going to be on vacation so I figured I would take care of it when I got back. Well, jump starting a person in need was just a coincidental event to the problem with the sway bar disconnect. Evidently the sway bar disconnect circuitry is connected to the CAN bus. When water gets into this device as it has now on three of mine, it submerses the circuit board and things begin to short out. Well, in this case, the CAN bus was being drawn down and this accounts for all of the miscellaneous stuff that was happening on the dash, with the alarm and with the key fobs. I had them disconnect the cable to the sway bar disconnect and all went back to normal in the Jeep. Right now, my sway bar light on the dash is flashing but all is now working normally. If the disconnect is out of warranty completely now, I'm not sure what I will do with it. I'm thinking I will take it down and see if I can connect it permanently while I work on the disconnect. I would like to see if I can replace the electronics without purchasing a whole new one. That is if it is no longer in warranty. Well, that is what happened. Computerized cars, love them or hate them! Sometimes both!|

I removed the battery terminals from my jeep the other day to run the wires for my new winch. Once I finished I connected the battery terminals and then my keyless remotes wouldn't work and the jeep would start but only run 2 seconds before dying. I then removed the negative terminal to reset the computer. Once the negative terminal was connected the keyless entry would work but the key would no longer engage the starter. It was like nothing was there when I turned the key.
After some google searching I concluded that the Wireless Control Module somehow died. My Jeep was then towed 60 miles on a flatbed to the dealer on them and they then ran some tests and determined that the Wireless Control Module was indeed bad. All was replaced under warranty and everything is right in the world again.
Also, you cant install that part yourself as it has to be programmed by the dealer on their computer with your remotes. Google Wireless Control Module for Jeep Wranglers and you will see how hokey the electronics on our Jeeps are.

|jadmt||I have jumped started numerous vehicles with my 2013 JKU. I use the positive battery post on both batteries and then ground post on mine and on the other vehicle I hook the negative clamp up to some solid metal on the car not to the battery post. I hook up the positives first and be careful not to let the ends touch. When done I pull mine first, Never had any problems.|

|Dakovich||I've always been told not to jump-start people with a modern vehicle due to the chances of frying the computers. Not sure how valid that is, but it seems plausibly true.|

I'm new to JKU's, but I'd suggest leaving the pos/neg terminals off for a while, which the caps in the ECU discharge, so that you get a full reset.
I'm not sure it will work for vehicles, but I'm an embedded engineer and we sometime need to discharge the caps at the controllers to get them to reset completely. It is easy to try though. I'd say 10 mins should be fine.

|JKWrangler2012||My key fob occasionally is ignored by the jeep... Rig has never been in water above a few inches... It's a jk thing?|

|DirtyTeddy||The other week my key fob wasn't working, walked inside to grab my mustang keys and then the jeep fob works, go figure. But that's because I put her in 3 feet of water a month back|

Good deed jumpstart -->> now computer gone mad!
I'm at a campground in Maine near the Canadian boarder. Just got there and someone there was having trouble starting their car. I gave them a jump start from mine. Then problems started with mine. I parked at a picturesque site to take a picture, went back to leave and the jeep won't start. Looked under the hood and the positive terminal is loose. I tightened it up and then the jeep fired up. I had to travel another 30 miles to my destination and the gremlins began showing up gradually at first. The BAS/ESP light and traction light came on, the oil light intermittently came on, and the RPM kept going down and then back to normal. This was happening at odd intervals. I bought a battery terminal cleaning brush and cleaned up the terminals just in case there was some issue with a bad connection. The jeep appeared normal after that. Then two false alarms of the anti theft alarm. Went into town and the gremlins were back on the way in and then parked it. Came back and it wouldn't start. Then it started ignoring my key fob. Ordered up a flat bed and she sits at the dealer waiting for it's brains to be unscrambled.
Anyone else have this problem after a loose battery terminal?
