My rc 390 2017 is displaying CAN EMS FAILURE, i toggled the kill switch and went okay but the it keeps the fuel pump on so i decided to remove the battery. After 10 mins, i installed back the battery and kill switch is not working anymore aside from that, fan is always on even if without the key and the panel displays JP 5.0.3 Maybe u guys have any idea?
