I have a 2016 L3901 that is showing several different error codes. First it showed P0087 and P0629..I changed the fuel filter and cleaned the water separator. The tractor has always ran. I read somewhere to clear the error codes, you push the regeneration button and the one next to it at the same time before turning on the key and then turn the key on while holding them in, and this would clear the codes. It didn't work for me. Does anyone have any good advice on what I need to do to clear the error codes? Thanks in advance for your assistance

P0629 is a fuel pump circuit code I believe (trying to go from memory at the moment) p0087 would be related if the lift pump isn’t working. I would start with checking the wiring to the electric fuel pump
edit: forget the above (I have automotive codes stuck in my head and Kubota doesn’t always directly translate)
I would start with checking the wiring between ecu and scv.

beat me to it.
Either a wiring issue between ECU and SCV, or perhaps a failing SCV. Look for evidence of rodents on/near the engine-have seen that before.
Also do a free flow test on the electric lift pump make sure it's flowing good.
if code cannot be cleared from B mode in the panel, a problem still exists.
