I drove my 4XE home, charged it, and when I started the next day. I get the message SERV 4WD under the battery percent. Anyone know what this is?
I'm not quite sure what you're asking. But when the serv 4wd light is displayed, the Jeep will be in 2wd and unable to use 4wd. It might be a software issue or a bad or damaged sensor among other things. Check out this JL thread where a temporary fix was made after somebody put a lift kit on and the ABS sensor was damaged. It'll help explain better than I am.Even if it does go in to 4A it will never use 4WD?
Take it back! We had several erroneous messages when the entire system failed and had to be dragged out of our garage! They had to replace the entire Power Inverter Module! They need to issue a recall
It’s fixed! He posted the fix they did under warranty 2 months ago. Read!!Take it back! We had several erroneous messages when the entire system failed and had to be dragged out of our garage! They had to replace the entire Power Inverter Module! They need to issue a recall
If you need assistance while your Jeep is at the dealer, please let us know!We got this about a week ago, around 1700 miles or so (at our 200 miles a month use ), it came and went a few times. Switching from 4H Auto to 2H Auto and it disappeared, I guess since you're not requesting 4WD. Had a couple of engagement attempts, where I could feel the front kind of trying to lock, I understand this subsystem is the FAD, (Front Axle Disconnect), and this could be the electro-mechanical part or the supporting electronics.
Over a few days it got to where it pretty much comes on in 4H, so been using it just a little in 2H, the traction control disable light came on one time when I was backing up and it was trying to engage, but that's probably a phantom related issue, it disappeared with a power cycle and stayed off.
I did do a another round of seating the fuses/relays, I had done this preventatively about a month after we owned it. Also checked a specific harness someone on another forum said was disconnected and caused this issue, but it's firmly connected.
So I made an appointment We're going to drop it off in a couple of days, drives just fine so no sweat getting it up there (dealer is only ~8 miles away), hopefully this will be a quick fix per some other folks who have dealt with the same issue (and it's not 4xe specific).
Thanks.If you need assistance while your Jeep is at the dealer, please let us know!
I don't mind the service requirement, shit happens So I'm hoping it's simply a matter of quickly identifying the issue (it's apparently pretty well known, I even have some service docs to show them), making the fix, and getting the vehicle back.
