Yuneec E-GO 2 – three yellow flashes FIX – ECU replacement

Got three yellow flashes on my Yuneec E-GO 2 Electric Skateboard.
Here is the fix and guide how to fix – solution and resolution.

Yuneec E-GO 2 USER GUIDE Manual
3.5. If during your ride the board stops and the controller’s blue light is flashing
one to four times, followed by three yellow flashes and is accompanied by
vibration, it means the board has been overloaded or is being used on in-
clines greater than recommended.

Yuneec support was contacted. Three yellow flashes is Electronic Control Unit (ECU) failure. ECU replacement needed.
Draft plan and calculation:
Option #1
1. Buy new ECU (~$100)
2. Send board to Yuneec center (~$20-30)
3. Labor for ECU replacement on Yuneec center (~1hr $80)
4. Send board back (~$20-30)

Option #2
1. Buy new ECU (~$100)
2. Replace ECU yourself (easy procedure – screwdriver required)

Full ECU replacement process, testing , remove syncing.
Successful Electronic Control Unit (ECU) replacement and test drive.
