Power Steering Pump Failure???

[Bear667]

I’ve searched and can’t find it. Anyone seen these before?

2020 JLURD, RNR steering system with Apex boost and cooler.
Power steering will just randomly stop, but I can turn off Jeep and turn back on or clear codes and it will reset and work again (anywhere from a few miles to a few days) it seems to be getting worse though and happening more often. Although it is only this one fault and no Christmas tree, fuses and batteries are good.

My thoughts:
1. Steering pump going bad and sending bad signals to CAN and stopping until reset, but why would it reset?
2. Bad CAN BUS or connection to the CAN BUS, but I only get one fault…

let’s say going to dealer is the last resort, no warranty

I'm having similar issues, wondering if you got a fix for this? I've done battery replacement and green CAN bus replacement. Checked grounds and fuses. Thinking dealership is the next stop.

One member here had a loose connector. So, you might check it.

If you don't find anything obvious, I'd probably move to a PSC system. But, I'm running 37s and wheeling in the rocks a lot. While you could buy a take-off from AMW 4x4 or Rubitrux, etc., it might be time to just move to an engine driven pump like the PSC. My latest setup is the Apex with cooler pushing my 37s. But if it hiccups, I'm going to a PSC.
