Hello, guys. I had recently an error code “30” on my bafang G10/M620 52v motor. I have checked everything and eventually found the issue, namely the e-bus harness was damaged on the controller side I could solder it if I really wanted to save on money, but decided to buy a new UART controller from Aliexpress to have it nice and tidy. It arrived and I replaced it while I was being excited to ride my bike again. However, despite that everything looks fine, front/rear lights turn on, brake lamp works, no error code appears on the display (only in the memory I can see the old “30” code) yet the throttle and pedal assist just don’t work. The speed sensor works, because when I am pedalling, it’s showing the speed of the wheels. I removed the motor again to check the harnesses and connections, but everything looks alright.
Does anyone know for sure if it’s a calibration problem? Do now I have to buy a c691 display from greenbikekit and do the torque calibration?
I don’t want to buy it if it’s not the case.
Please, whoever had similar issue or an expert of this motors give me some hint.
Thanks in advance!
