My JK is sick...

This morning on the way home, it decided to flicker the head lights, power out like radio/AC/dash lights/speedo all briefly went out, the traction light, emergency brake light, and a few others came on, the bell started dinging, and then everything just came back on.

Then a few miles later, it did it again. And finally one more time as I turned into my neighborhood.

It's a 2013 with 20k on it. The alternator couldn't be out could it?

It sounds like an alternator. 20k miles would be way early for one to go out on you. But, stranger things have happened.

Check the tightness of the connections to the battery.

Load test the battery.

The factory battery in my 07 JK died within the first year at 11K miles.

Dealer replaced under warranty no questions asked.

Judging by the mountain of dead batteries they had behind the shop it's quite common.

The charging system, to include the battery, needs to be checked. Your battery and alternator should still be good but there have been problems. At least you're still under warranty.

Loose ground. Start with the battery then check the bolt by the tipm

My 09 did the same thing as the OP this morning. What is this "short in the steering column syndrome"?

I will be checking grounds, battery terminals, TIPM connections, etc before going this route.

I bought one from ClayR for $1900. I keep hearing stories but then I realized I have a vehicle for life! Also they tow and give rentals for free.

Load test the charging system to include alternator and battery. I am 90% sure this is your problem. Autzone does this for free.

Why would you want a maxicare warranty just because someone's battery cable was loose?

It did it again this morning.

The headlights flicker, the seat belt bell rings, the traction light comes on, the emergency brake light comes on, the radio goes out, the speedo goes down to zero... except this time it bounced.

It was almost as if there is a wire bouncing somewhere because it would come on and go off and come on and go off, all within a few seconds.

I checked the ground on the battery last weekend when it happened and it was still tight. I haven't load tested anything, but I'm going to take it up to the dealership on Monday... if it doesn't leave me on the road before then.

Another vote for the alternator going bad. Had this happen to me before.

tipm is the fuse box. "Totally integrated power module". It's a lot more complicated than it looks.

Mine was caused by a squirrel chewing 4 wires that eventually caused a no-crank condition.

Apparently there was three "mini" recalls that needed to be done, two if which had to do with the TIPM. They think they've fixed it although they can't be sure. Just have to drive it and see.

Well they didn't fix it. It did it to me again when I was nearly home, and then it kept doing it. This is a video of it wigging out! I was going about 20mph in my neighborhood.




And their first question was "is that an aftermarket stereo?" So I took mine out this morning and put all the factory stuff back in. Can't say anything about it now!

I'm wondering if my amp is burnt and shorting everything out. I had it hooked to both the power and the ground of the battery. I never shortened the ground to 18" as recommended.

its absolutely fine to hook your ground to the battery. In fact, that's how we hook winches up, and they use substantially more power than an amp does.

On an amp, it just wastes a bunch of wire, which is very difficult to route in a decent way.

Ok, I removed the aftermarket stuff, and reinstalled the factory stuff and drove it like that until I traded it in two weeks ago. It never did it again. So I know that its something with my HU, my amp, or my wiring.

I reinstalled my HU in the new 2014 JKU yesterday. This setup contains the HU, the Sirius adapter, the stock antenna adapter, and the RP-CHY-4 adapter or whatever it is. Everything worked fine.

This morning my steering wheel controls worked fine, but this afternoon they were intermittently working. I thought they only worked when I had the brakes on, but as it turns out it was because the braking action was causing a wire to touch the metal and short the adapter out.

When I got home, I took my dash apart and confirmed this. The 1/8" plug coming off the RP-CHY-4 adapter was hanging down and touching the metal A/C vents. I moved it and they worked, I touched it to the metal and they didn't work. So I taped up the plug with electrical tape so that it can no longer transfer power and short out.

My question is, what is the possibility that this is what caused the issue in the other Jeep?

If you've tapped into the can bus system, very likely.

I dont think I've tapped into the CAN BUS system... Everything I did was plug-n-play.

The PAC HU wiring kit taps into the CAN BUS system to fool the computer into seeing that a HU is installed. You might be able to find a pinout for the SCW adapter online or in documentation that came with it. If so, try to identify the wire on the diagram. Chances are good that the wire in question is a CAN BUS C +/-wire, which causes all sorts of problems when shorted.

But, your post has me thinking about mine now. I don't remember if my 09 did this before I put my HU in.
