BBSHD error 30, controller fried?

[Bafangert]

Hi,

My lastest creation is a Cannondale with a Bafang BBSHD 1000w. I have made only one ride and it's never programmed.
Now error 30H is displayed. Battery is fully charged, but in display it shows 0%

All connectors checked for moisture/oxidation/bend pins -> OK
Main wiring harness checked -> OK
Battery fully charged (giving 52,8v) -> OK

So I have tried to program my controller, but I can't even connect with a programming cable.

Does anyone recognize this problem?

Thanks in advance!

Eric

If it is working otherwise, the controller isn't fried, but either RX or TX pin to the display is broken.

Programming cable uses the same pins as does the display.

Bike/motor/throttle is not working. Trouble code 30H.

1) Tested the main harness for broken leads, every wire beeps so there is no interruption.
2) Tested the battery with a multimeter and it registered the proper voltage around 58v.
3) The display turns on and gives me the proper battery voltage but the battery percentage and meter reads zero.
4) I tried bypassing the screen by using the USB dongle method.
5) Using the programming cable does not even work, I can not read any settings (or even connect to anything).
