ABS, TCS, Serv4wd head cratcher

Hooked
Like the title says, all those lights are up. Drove just fine the night before without issue. This popped up the following morning. Figured it was probably a speed sensor so I took it to autozone as my code reader doesn’t read ABS codes. As soon as he plugged in, dash did a big cycle and check engine came on. Here’s their printout.

Got it home. Cleared the check engine light with my reader, but still have these codes coming up. Wiring looks good. Fuses are good.

signs of critters...

check the connectors and wiring under the fuse box and on the PCM

I'd invest in a harbor freight inspection camera - they have the same one I use on closeout for $20 and check the wiring that's around the bell housing (where critters are more likely to hang out)

That many codes overnight, my bet is something got chewed up.
 
Communication codes can be tough. I always started with checking the battery, especially if they all appeared upon start up. You can see all the modules lost communication.
 
If you check everything else out and you don't find it, look at the CANBUS in the cabin.
People have reported the whole terminal strip has gone bad and replacing it cures the issue(s).
 
Thanks guys! Checked everything except under the fuse box today. Lots of dirt but nothing chewed so far. Gonna pull the box tomorrow and report back. Thanks again!
 
Sorry for the late update. Whole family got super sick so I didn’t get to it until today. Pulled the fuse box and it all looked good. Not sure where to go next. Still under 60k miles so I might just send it to the dealer. Hopefully they’ll cover it under powertrain since the serv4wd light is on. If not, just gotta pony up. I fortunately have a 3rd vehicle to drive around but it really sucks not having this thing up. It still drives just fine, but not knowing what’s actually causing the lights makes me not trust it enough at the moment 😆
 
🤦‍♂️ so this thing has been driving me crazy because none of it made any sense… so I went back through and ran my hand down every single wire I could reach. Found the right rear speed sensor wire was chewed up. Thought for sure it would be something up front with all the other codes that popped up on auto zones printout. I cleared those with my code reader and the CEL hasn’t come back on since. Their reader might’ve triggered all that crap. Anyway, called local dealer and that sensor is on nationwide backorder with no ETA. Found one at some mopar parts store online who supposedly have only 1 in stock. We’ll see how that goes.

As for the culprit, we adopted a damn dog who apparently doesn’t have enough shit to chew on so she decided to attack the trucks speed sensor and rear driveshaft boot 😡 missed the sensor on last check probably because it’s so close to the rubber sleeve.

I'd cut it on both sides leaving enough to splice wires in line, add double layer of shrink tube, wrap it with tape and call it done - trail fix (y)
 
Try Bill Estes Jeep in Brownsburg, Indiana 317-854-0239. They're on Eastern Daylight Time and hours are 7:30 - 7:00 M-F and 9:00 - 6:00 on Sat, closed Sunday. Again, Eastern Daylight Time, we're 6 hours ahead of the Islands.

They were the only ones that had the driver side rear when I needed it.

Or, use the part number on ebay, may not be OEM but they look exactly alike.
 
this fuckin dog… I went for an overnight trip to Kona with some friends. Planned on splicing the damaged portion when I got back… dog had other plans. The line is now completely severed at a different point. And she decided to attack the brake line as well 🤦‍♂️.

new line came in. Now gotta order another brake line from evo.

Could you put some spicy hot sauce on the wires and hoses?

Thought about it but don’t want to attract rodents. I have an 8x10 kennel I could fix up and put her in at night or when we leave. Hate to do it but I might have to put her in that.
