My Shimano Steps-powered e-bike is frequently but irregularly giving me the errors E010 and E012. In the E6000 Series Dealer’s manual and E8000 Series User's manual I found the following:
E010: A system error was detected. Power assistance is not provided during riding. Press the power button of the battery to turn it on again. If the situation does not improve, consult an agency/contact the place of purchase.
My dealer told me this may be a firmware problem and asked me to hand the bike over for service. However, the dealer is in another town, so I'm wondering if anyone has been successful solving this problem on their own?
