Losing engine gauges, speedo, and fan staying on

If someone on your behalf could plug in with ESA that would be beneficial and can narrow the issue down in case there is something on the IP side causing problems. Unfortunately without an active issue if tough to find. I wouldn't recommend tearing wiring harnesses apart, stick to points where its tied up or braced, cut ties and check for rubs.

No, don’t have that code at all. I have no active codes. From when it was acting up, I have 2 inactive, J 1939 multiplexing, and ABS abnormal update rate. At one point, I disconnected the entire abs system, and pulled the fuses, and it didn’t help. Prior to that my shop guy checked it with Acom, and found two active abs codes.
It definitely seems like a fuse problem. It’s been fine for 2 days. I replaced some fuses, and gave the fuse panel a good look over.
My elog gives me codes, also. They are different than what Insite says. See picture. But those elog codes have been around for ever. I don’t pay much attention to it, or really trust it.
That’s all I know right now. I’ve pulled and yanked on every wire and bundle I can find, and nothing changed.
