Battery fault

The drive cannot communicate correctly with the eBike battery. Frequent causes are dirty or corroded battery contacts, a battery not seated properly, or a non-original battery; an internal battery electronics fault is also possible. Bosch's official procedure is to switch off, remove and reinsert the battery and restart.

How to read e-bike error codes

Unlike cars (OBD-II), e-bike codes are manufacturer-specific: the same number means something different on a Bosch than on a Shimano system. What matters is always the combination of drive system and code.
