No. Since there’s no warning light, I didn’t install the ET to see the active code. I bought a adapter come together with a 2019 ET copy, it has to be reinstalled each time because it expired within hours

There can be Codes present without any indication on the panel. Strange I know but it can happen. So until you do get ET hooked up to it in order to see what's happening in the way of Codes/Events you are literally flying blind.

my 2 cents worth. disconnect the aftermarket turbo timer and check again. i have seen them cause some strange problems over time

Finally it is the left joystick’s fault base sensor that caused my 246C park brake stay engaged. The tricky thing is that there is no alerts at all. But if study the joystick’s position value by percentage, it is abnormal. I confirm this issue by swapping left joystick base with right hand one. Park brake can be released right away, working cylinder keep extending while the joystick is in neutral position. This explains why the ECM won’t allow park brake been released, if not the fault joystick will continually send signal of wheeling even the joystick is untouched.
No alarms for this fault, will need experiences to solve this issue. Technician from Caterpillar dealer should be quite familiar with this issue, it should be easy for them to identify this issue.
