DUALTRON THUNDER 2 Error

EY3 LCD Throttle Assembly

The EY3 unit houses the logic board that converts mechanical trigger movement into digital signals via a Hall effect sensor. A generic error typically signifies a failure in the UART communication bus or a sensor voltage out-of-range condition, often caused by internal PCB corrosion or mechanical displacement of the trigger magnet.

Main Controller (Motor Controller)

If the throttle assembly is functional, the logic gate on the motor controller's receiver end may have failed. This prevents the controller from interpreting the throttle's signal, though this is statistically less common than peripheral failure.

6-Pin Communication Harness

Physical fatigue at the scooter's folding neck can lead to internal fractures in the copper wiring, specifically the data lines (TX/RX), which severs the connection between the display and the drive system.
