Sorry but I have no idea. Was an auto tech for 24 years, worked on drivability complaints all the time, before we had the built-in diagnostics like we do now. Had to pinout everything to test but at least they gave us codes that meant something.
Hisun really needs to get better at getting out diagnostic info. Seems like they have a bunch of rouge programmers out there with each doing their own thing. Really a pity.
Thinking about the lemon law with mine. Not a happy camper here.!
Sorry I can't help You. I know how you feel!
