hmm... yes

disconnect the 3 blue wires and the 2 pink wire connector from the motor control. run the diagnostics
--if still f-70 continue on to see if the interface or ccu is bad.
--if f-28 then most likely, your mcu is bad.

reconnect your motor control. check for 5 volts DC on the user interface wires at the user interface. its labeled UIP on the right side interface board. disconnect UIP and measure between the outer most pins.

if you have 5 or -5 volts with the mcu connected
--then most likely its the ccu or right side interface.

if you do not have 5 volts, check again with the motor control disconnected.
--if 5 volts, replace motor control.

It is never a bad thing to leave it to the professionals. Inexperience can lead to more damage or risk of injury. You can always call A&E Factory Service (1-800-905-9505), Sears(1-800-469-4663), or local service man you can trust (
