Just got this at an auction for cheap. Wrench flash I assume indicates there's a fault, but default code(s) don't work to access DTC. 55555, 12345, 54321, and about 10 other random attempts.

Everything works except travel. Travel is.001 MPH but it sometimes surges if you floor it.
I assume I'll have to get a tech to reset the Service Password, but until then I'm looking for an easy fix. Has 54 hours on it. 2007. I think this got parked for a decade+ not working.

While I was trying to "work out" some unknown corrosion? I was driving it around in what feels like limp mode, and it would blast away at full speed, then quit, then go again randomly. the 3 main leads from the controller were getting very hot, so I stopped.

Without accessing the service DTC with password, it does flash "1" and sometimes "3" and sometimes "11".

I decoded the model number and seems like it should be 36v system, but all the controllers say 48v. I though that was weird, but I'm new to this.

Thanks,
Kevin
