2012 Mule 4010 Trans - DFI Light and Electrical Smoke
 

Good afternoon. My parents are having an issue with their 2012 Mule 4010 Trans. It only has about 250 hours on the clock. It has been running rough and low on power with the DFI light illuminated. I honestly thought it was a bad fuel issue. Today I was running it up and down the driveway to try and blow out the fuel system after draining and replacing with fresh fuel. As I drove it at 'full throttle' (I put that in quotes because its about a quarter the normal full speed), it came to a stop, stalled out, and a cloud of white smoke poured out from under the seat. I lifted it to see a jet of white electrical smoke pouring out the left side of what my research tells me is the ECU. I tried restarting it and it cranks and the smoke returns, but no start.

The module that was pouring white smoke is behind the battery and labeled as part number 21175-0332. As I said, Google-Fu tells me this is the ECU. Are there other parts I should inspect and/or order along with the replacement? I live almost 3 hours away from them and would like to minimize the travel back and forth trying to fix it.

I would appreciate any advice or info the group could provide.

Ecu burning up on mule
 

Hey I’m having the exact same issue as your parents. Same ecu number and all. Replaced ecu and dfi light is still on and runs like crap. Did you ever figure it out??
