Wow, very cool post, glad you got it fixed.

 

i did the same and then got high quality electric tape around the whole wire bunch from the area up to the middle pillar where it goes up and not in the rear footwell

 

That is a good Idea! The wires are sitting on top of the carpet and are very prone to getting wet. The main reason for this failure is the cloth tape covering the wires in question holds the moisture and corrodes them (very poor design). I mean really it is right next to your foot and I do not wipe my feet before getting into my jeep, come on man. Waterproofing the whole bunch while you have it apart is a great preventive tip. I think one of the main reasons mine failed was it has been snowing out and been below freezing until the day it happened we had a thaw. All the snow and salt that accumulated on my drivers side floor melted and easily found its way to the weakest point the cloth tape.

 

Awesome job on the pictures newmanbr. This was an often suggested inspect/fix item for the dash lights on, but no one had taken any pictures before. Reputation score added! Mods, this should be archived in the knowledge base section.

 

I am having similar problems with the ABS, ESP and snake lights on my 2009 4WD. Just checked the same wiring harness and the looped pink wires had been encased in a plastic shrink-wrap with some sort of wax filler to keep moisture out. I guess Jeep did away with the cloth tape at some point.

 

I know this is an old post, I have a 2014 with the similar issues, my 4x4! Light and traction control light stay on, did you ever find a solution?

 

They make an electrical crimp fitting that is considered "gas-tight" meaning it will not support corrosion in the joint. I suspect these cost 25 cents when what this harness maker did cost a nickel!

When I was a factory engineer designing electrical components and harnesses for an industrial environment where heat, moisture and other extremes existed, we always err'd on the side of reliability. Of course, we were "cost+plus" on the pricing...

My 2007 FDII patriot (US) does NOT have this loop in the wiring harness. My ABS light is on in addition to the other lights listed. Also the cruise control will not engage. I think my issue is a wheel speed sensor. Jeep must have used a different wiring harness after '07 or on the non US patriots. Also the electrical tape surrounding the wiring harness is not cloth but plastic. Very interesting.

 

I have the esp/bas, trac control, and abs lights on as well. Took it to the dealer and they wanted to replace the abs module and master cylinder for $1,200. I checked the wiring problem and they don't look they're in very bad shape to me but I'm not 100% sure what I'm looking for. Do these pictures look like good wires?

 

Thank You

I know this post is a couple of years old but because of it I was able to quickly locate these wires, remove the tape and find the corrosion which was causing my ABS to go haywire and causing all the issues mentioned above.

Thanks!epper:

 

Had the exact same issue with mine, pictures are exactly what happened to mine. I used a wire nut to get the 4 wires together, then electrical tape, and voilà. Hopefully it will last another 11 years and a half.

 

Hi,

I had the same lights on my dashboards, ESB/BAS, and the snake thing, and the 4WD (not 4WD!) however I try to spot that four wire but didn't manage to find them, here a picture of the wires driver side.

I try to look in that many wires here but couldn't find the loop of 4 pink wires.

If anybody have a clue on where could I find them, or maybe I don't have them, It's 2007 model 2.4L manual gear.

Thanks,
David.

 

If you still haven't found them, mine were right where that wire tie is at. So you might need to open up the wires in order to see that loop with the Pink Wires. Also under the hood, then under the Fuse Block, the wire that goes to the 4WD Fuse sometimes gets corroded as well. This mkes me thing that there could be a ton of other failures like that one. If 1 wire can corrode, it only makes sense others could as well.

 

I have the same problem. 2014 Patriot Latitude 4X4.

One independent shop said "Probably differential"
Second Dodge/Jeep only independent shop said "Too new. FCA won't let us have re-flashes and downloads. Go to the dealer."
The dealer said "We can't find any problems. It did store a code so we know you're not lying but we hooked it up to the scanner and drove it around. Everything is working as it should."

I drove it home from the dealer, tried to climb a small dirt hill (20 yards maybe?) on my property and about 3/4 of the way up, the rears failed, the fronts started spinning and the "4WD!" light came on and flashed.

I checked the wire harness on the drivers side kick panel, apparently by 2014 (2011 refresh?), they redesigned the cheesy wiring splice so that's no longer an issue.

I checked the wiring under the relay below the driver's headlight, it looked fine. I pulled the relay, none of the spades looked cooked. Same with the wiring under the 15 amp 4wd fuse....so I'm about out of the normal You Tube fixes.

This car has seen nothing but highway miles from super commuting and snow a couple times a year, it's never been thrashed.

I'm at a loss here.............

 

I just watched a guy who unbolted the ''Fuse Block'' next to the Battery & the group of wires that plug into the bottom of it that handle Fuse #2, the fuse that handles the 4WD & in that plug, he pulled out a wire that was corroded on the end, pealed back the wrap about 1/2 inch till it was all good copper wire, put it back into the plug, then plugged it back into the Fuse Block & the 4WD! Light was off. What worries me is if it can happen to 1 wire, there's a lot of wires that could also corrode. Mine turned out to be a missing fuse in the #2 slot. That solved my problem but I was ready to lift that Fuse Block tomorrow & check that Plug that handles the #2 Fuse Slot, or 4WD! Light issue....

 

Puzzling Idiot Light pattern?

Hi all, I'm hoping for a little help with a strange problem. Riding down the road yesterday, for no reason, I heard the warning "ding" and the following idiot lights all came on at the same time: "ABS" light, "ESP/BAS" light, "ESP" light (the little car with skid marks), and the "4wd" light...

Do You still have your Patriot ?

 

Reef do you still have your Patriot ?

 

Than

 

I believe that Jeep either corrected that issue or the previous owner had that fixed along side the door. At any rate if mine isn't a corroded wire related issue, it could be something with a bad ground or because larger tires were put on the car. I'd replace them but they're really good tires Michelin, that still have 50% life or in other words, 30-35k miles left on em. I hate to spend the money on tires if I can find a work around.

 

You can check the relays & connectors from up under the hood, but to really work on that relay box it's far easier to access it from the wheel well. There's only a few screws and plastic clips that hold the wheel well liner in, and it quite easy to get to.

 

Thanks for that..! I've had the well liner off in the past and have the cool little tool to pull those clips out.

 

 

I know this is a long shot.. but I purchased a 2008 limited Patriot.. it is in really good shape ,, obviously it has all the CEL lights that is mentioned in this post..
My issue is that I looked at wiring harness in the drivers doorway,,, I have the exact layout except I have 6 pink wires.. the wiring harness was all wrapped in blk tape
when I took it apart.. all 6 wires came apart in my hand no idea how it terminated .... any idea or help will be much appreciated.. thank you

 

Hi JHudson, welcome to the forum.

Member "poman" only made one post back in 2014, and they haven't been active since, so I don't think they'll respond with a fix.

Along with corrosion on the wiring splice under the kick plate, a bad wheel speed sensor or it's associated wiring can also be the cause.

I would recommend getting a code scanner, and seeing what codes are present to hopefully narrow things down. If you don't have a scanner, a local auto parts store might be able to read the codes for you for free.

 

Is there any way to test for a bad speed sensor?

 

To test them, you would either need a code reader that does live data or an oscilloscope. It's easier to just read the codes.

 

That is a good Idea!
