We received the S00079 part and the mechanic installed it. When he ran the procedure for "Regen Throttle Sensor Adjustment" (without diagnostic cable), there was no response - i.e. no speedometer needle movement or response of any kind.

Does this mean that the controller is damaged? If so, what are our options? Or, what could be other possibilities?Please advise.

I am feeling rather discouraged that this could be a dead bike just due to it being dropped (i.e. not an unusual thing for a bike).

Thank you for the confirmation - much appreciated!
