I have learned something now. Thanks

They hard wire it to a clean metal surface area to have the least resistance in the circuit. Having a ground tied to other grounds can cause resistance issues as well as other issues. Not to mention that a ground can be overloaded if it is a smaller gauge wire and has to many circuits on it. So the vehicle is broken down into sections with grounds in several areas to keep the ground wire run short as possible. The longer the wire, the more resistance in the wire so the ground is not good.
Some modules are also high current modules and need a larger wire than what would be desired to run thru a long body harness, causing the harness to be rather stiff. With grounds, the shorter the better, a ground that is over 13 inches long can also become an antennae picking up interference which may be undesirable to the module.

That's crazy, I spent a month trying to figure out what was causing my ESP BAS ABS and traction control lights to stay on. It was 2 weeks after I put on my lift. I must retorqued the suspension parts at least 3 times and checked the steering wheel 10 times. It turned out being a ground wire for the ECU/PCM not making a good contact with the module. You'd thing they'd hard wire the ground to the PCM instead of connecting it to one of the mounting screws.
In either case. I'm gkad you are back in the game.

|jmb6420||Glad to hear it. There's nothing worse than a new toy you can't play with!|

Still ging strong..........
Three days, since out of the shop and still running STRONG
Damn, I LOVE driving this thing

On another note I'm glad its fixed and it's also nice that they were able to isolate the problem so that you feel more comfortable in the Jeep vs the phantom problem that just fixes itself.

|CLOTAGAMES||Electrical issues are one of the hardest to find-Glad they got it fixed. Factory wiring diagrams are usually pretty poor.|
|12-10-2011 06:39 PM|
Can you get a picture of the ground location?

Shop notes for you folks...
Picked her up this AM and been in her all day running errands!
They even showed me the location of the ground fault.
The notes from my 2nd visit:
“Diagnosed and found damaged coil and checked for shorts. None found. Found voltage and ohms are the same as other cylinders.. Replaced PCM & Test Drove. Coil popped again????? Instructed to hard-wire coil per “STAR” & replace coil. Found Map Sensor, TPS, & ETC ……. Lost Grounds. Found wires grounding against AC Line, repaired and insulated wiring over AC line.”
So far she is running like a top!
Being back in my 2012 JKU is as good as REAL sex

But damned if the gremlins weren't banished each time when the ground connections, ALL OF THEM, were inspected and cleaned if necessary.
Unfortunately, I have no idea where they all are on a JK yet.
I sure hope this is the resolution for you!!

|Up Hill Bill||
Great news, Willee.
Now, get out on (or off) the road and enjoy our new Jeep!
|12-09-2011 10:00 PM|
|fawsty||I think I would take the seat covers, and any other add-ons with me to the dealership, and tell them to install them, seeing that you couldn't in this whole process.....Just don't make them put the lift on it.|
|12-09-2011 06:19 PM|
Told ya, I had the faith Willee--
|12-09-2011 06:00 PM|
Yes I screamed out load.
|12-09-2011 05:46 PM|
|LaTuFu||Glad to hear that it was resolved.|
|12-09-2011 05:43 PM|
Yes; Electrical problems can amount to chasing ghosts!!
I am glad for you that they were able to find it. Sometimes it has to be a major short before it can be located. Also Kudo's to the servicing dealer for putting in the effort to find it. Hope the best for you. And good luck on your upcoming retirement!!
|12-09-2011 05:27 PM|
That is good news!
Holy cow....that must have taken a long ass time to trace....
Electrical gremlins suck....

|flyinion||Congrats!! Wow sounds like you just got the random bad piece of wiring. It could happen to anything. Could have just been a small nick in the insulation that wasn't caught in QC when they built the harness and then it just happened to make contact with something due to its location. At least they found it|
|12-09-2011 05:01 PM|
|cosmos||I hope it really is all fixed and this just becomes a funny story from way back when you first got the jeep|
|12-09-2011 04:50 PM|
Think it's fixed.......
Got a call at 5:30pm this afternoon, from the Jeep Service Shop, saying my Jeep is fixed?????? Took the poor guys almost 2-weeks to locate this hidden demon and yes, they were doing their BEST?
It was a ground-wire, making contact with whatever?
They separated the two, it then started (believe it or not) and they drove it over 20-mi, no problems.
How the HELL can something so SIMPLE, cause so MUCH trouble and be so damn hard to find? Miles of wiring, covered, shielded and in extremely difficult to get to
Again, this seems to be limited to only my unit as far as I can find out.
Words cannot describe how much I want to get back in my JEEP
Thanks for the kindness and support shown me during this stresssful time
Now, I can install my new "seat-covers" that came while she was in the shop.
