2019 DF20a. Any substantial service manual changes from 2016-2019?

[doubl0h7]

I’ve found a reasonable service manual but it only goes to 2016 for my DF20a. Any big changes in the motor or should I find a more up to date one? Or does somebody have a link for a pdf I could download? I’ve been getting a flashing red light and reduced power after a few minutes. Is peeing fine. Swapped out fuel. USB OBD kit on order

You dont need the reader to see the codes.

The flashing lights on the gauge or the beeping tell you the codes.

eg 2 short flashes pause then 3 short flashes = a 2-3 code, which you can then look up on the link that Murray provided to see what it means.

The flashing sequence repeats over and over again, after a longer pause between each sequence.
