Here is a picture showing the failed diode D547 from the repair video circled in red. On my 2012 board (Nichicon PA4063RP120) that diode has been etched such that the marking code can't be read.
i traced that diode circuit forward thru the board to the inverting input pin 2 of a dual 2252A op amp IC522; i traced it back to pin 13 of the CN502 connector which exits out the OBC to either pin 7 or pin 9 of B25 of the three control connectors (10-pin B25, 12-pin B26, and 8-pin B27).
Could anyone help to identify a few items?
1. For some reason the pinout diagrams of B24, B26 and B27 are shown, but B25 is not found in the FSM...?
2. The diode in the yellow box area is marked "2U" and i can't find a datasheet for it; it is SMA sized.
3. There is another similar SMA diode marked "S4"--maybe Schottky 40V?
Similar size and marking type so probably the same vendor (Japanese?) but i'm not having any luck finding these.
