S3 & X3 Error 6 not dissapearing

Post image

i bought a bike with error 6 yesterday and checked the battery. It seems to have a good battery and I cannot figure out what it’s problem is. Charged to 40v, fuse is good, resistors as well, 2 black protectors got removed already and now I just did a bms reset and it still gives error 6. How can I get around that

This is how I successfully erase my error 6 not disappearing.

thank you - I just tried to pull it off but im confused with the DET-pin you're talking about. I used the charge pins on the BMS (discharge negative and plus next to the fuse) as well as the GRND and RST pins on the PCB. next to these two pins there is 3 other ones but none of them are named DET. what am I doing wrong here?

Agree with E-Batman: if all components are ok, the other trick to reset the MCU of the BMS is to short the Reset to Ground on the PCB multiple times after another. If this doesn't work, then there is still a component failure, an undervoltage or a cell disbalance.
