dealer said it was not the issue. and they dont know what the problem is.

***update***
dealer was getting false readings from the speed sensor/abs sensor that had already been replaced so next they replaced the hub once they did that all the codes they received said it was a bad ABS MODULE so now that is on order will be here next week (thur) . i was not going to pay for something that the first three dealers could not fix when i had my 3/36 so i called Chrysler and pleaded my case and guess what they are going to pick up the bill on whatever it takes to fix my jeep. happy days to Chrysler for doing the right thing

I've had this. Intermittently had service 4 wheel drive message and three lights amber lights for the ESP and two other I can't remember. It came and went a few times and then came and stayed. Shop said it needed a flash, charged me $55 and it went away, briefly. Then I got the message a few days later without the lights.

Gonna put her in again.

Service 4wd system

This thread helped me, even though it's from last year. Was working on a 2006 Commander, for a friend, had the issue of Service 4wd system light. Before I started on it, I thought the starter sounded unlike the familiar Jeep starter whine, I tried removing the negative cable, looking for anything shorting out, inspected the connector on the transfer case, and got the same result. I replaced battery and the familiar Jeep starter whine was good and the service light went away. My fix was a failing battery.

If you guys do heavy wheeling and see this with an ABS light, it is a wheel speed sensor most likely which will kill your ESC, ABS and the QTII. You have to use dielectric greae on all the connections to keep water out or you will light up like a Kwanzaa Tree :-) After I did the grease, my problems went away 100%. If it is only the service 4 wheel drive indicator, like the threaad says it can be a zillion different things.

Just had mine in the shop for this. The "service 4wd system" warning was intermittent, so I was affraid it wouldn't show up when I took it in, but a code did showing up. I'd have to reference the work order to tell you what the code was. The problem was the locker solenoid, so they replaced that and a wire harness.

Was it the front or rear solenoid that was replaced? Please say rear.

Also, just out of curiosity, how much did they charge you to do this work? I paid $23 per solenoid. I bet that they hit you for $500 on a $23 part.

I have both in stock at home for when I do the diff fluids in June 2011 (time at which I will be 15K miles since the last swap), but I was hoping that it was the rear. That is a lot easier to do on the XK since I will be taking the cover off anyway. The front diff cover looks much harder to get off. Normally, I just do the drain and fill plugs on the front diff.

My plan is to swap out the rear diff solenoid first. If that solves the problem, then I will not do the front one and leave it in my parts bin for when the rear dies again in the future.

If it is the front one, then I will swap that one too and keep the old rear one in my part bin for when the front one dies again in the future. My luck pattern dictates that it will be the front one.

The code was P1417
They replaced faulty FRONT differential control actuator/solenoid and harness.
Sorry man.
The Jeep is still under warranty until Dec, so it was free.

Doh!

I should have known. Asking was just a futile task.

It looks like I get to remove the front differential cover. I will still probably try the rear first, but I am not optimistic that that will help.

That cannot be a OBD-II code. That is an EGR temperature code in OBD-II space. It must be a code that can only be retrieved using a Starscan or whatever the Chrysler device is.

Kent,

Sorry I can't provide more info. My wife works for the dealership, so she just took it to work and they fixed it while she was there. She took delivery and, God love her, she doesn't know anything about cars. She just smiled and nodded when the service rep told her what the problem was. The info that I gave you up top is all I have.

On a tangent from that, I am assuming that they changed my front diff fluid if you are saying that you will have to remove your cover to get to the solenoid? It didn't mention that in the service report.

That is correct. If they actually changed the solenoid, then they had to remove the differential cover. If they removed the cover, then they had to drain the fluid. The fluid swap is probably burried in the parts and labor cost for the original task. I cannot imagine that they drained and returned your original fluid. That would be lame.

Good to know. I was planning on changing that soon. Thanks.

Replaced my front differential solenoid, and that cured my Service 4WD System light issues. It was a $23 part. I did it when swapping the front differential fluid.
