CAN fault N10-1 or A37
this one makes sense, all the rest can be ignored.

the E15/1 is simply just a switch. permanently "on" position means direct switching and N10-3 cannot control the shut-off delay or whatsoever... do you agree with me?

however, "door" position means the ground is controlled by N10-3 and therefore the auto shutoff delay is active.

the N10-3 get the signal via CAN from A37 on "door" position, and that signal is where our problem starts!

now, check that signal using wave signal while actuating the PSE (door open/close). you will feel the changes on voltage drop/rise that indicates the signal... and that is enough to know where the problem is. you don't have to evaluate the signal not unless your brain is programmed with interface on it. [:D]

i will leave the choice to you now. wiring? N10-3? A37?
