Problem with Mid Bafang Motor

[Fartsdump]

Hi to everyone
I have a problem with mid bafang motor, it seems not communicate with central unit.
I used it for about 1 year and half till one morning it decide to not work anymore :-(
The motor seems ok because if I use walk function or thumb accelerator the motor run, but when I try to use different levels from the central unit didn't work.
I tried to download new configuration (because I thought something got wrong on memory) but nothing happened. My suspect is that the central unit fail.
Any suggestions?
Thanks in advance to everyone

If you don't receive an answer here,you might try the forum at Luna Cycle. I've seen problems resolved by the "experts" there.

No worries about quality of your writing original-poster.

Because your thumb throttle and walk function still work, the problem seems to be your pedal-assist. Pedal assist relies on a signal from the sensor next to your rear wheel that is triggered by a small magnet on one of your spokes.

Start by verifying that the magnet is in place and aligned to pass near the sensor.

Next, inspect the sensor for damage and check the wire and plugs from the sensor to where ever it terminates. On a Bafang BBSHD and BBS02 that wire goes directly to the motor.

Good luck with this.
