This error is thrown when the ESC is unable to receive any data from the BMS/Battery. | |||
This may be because the 4 pin BMS data line has come unplugged or is not firmly plugged into the ESC. | |||
It can also happen when the battery is fully dead or something has killed the BMS board inside. | |||
