BBS02 Bafang Kit 30 H Error

[Easypedal]

Installed BBS02 Bafang kit on bike. Everything worked fine until I connected the two brake sensors. Display shows 30 H error. Motor still running, left break sensor works but not right hand one ? What could be done to rectify ?

It most likely is either the switch or wiring. Tracing with a multi-meter should tell you which. If you can't...don't know how.....to do that; take it to your friendly neighborhood bike shop.
