Hi to all!
I owner Meyra Optimus 2 with R-net control system.
Recently el.wheelchair had on screen error (3D01) and does not move.
Service manual says "M1 Motor Shorted Low"
3D01 - M1 Motor Error
This occurs when the control system detects that the motor connected to M1 on the Power Module has 'short-circuited' to a battery negative connection.
Check the motor, cables and connections to the control system.
If the trip is still present after the above checks have been made, then the controller may be defective.
I replaced two MOSFET. And no more errors.
But when I move joystick rod motor do not work.
The motor checked to connect the wires directly to the battery.
The motor works.
What do you think I need to check more?
Your suggestions and advice.
