Red triangle but good mpg

Given the amount of corrosion and lack of any visual evidence of leaking, could it be a short in the wires that connect to the relay? I'm just thinking out loud and doing some cursory searches on YouTube to find out more.

Thanks

 

No nothing shows up in the freeze frame and I've still not received a response from their support. I'm just probably found to end up returning the Autel honestly. If someone did not post the build 8 file here I wouldn't even have been able to run a full scan bc of it.

I think I'm going to get a new wire harness and bus bars and hopefully that will fix the issue. There was evidence that the corrosion got on to the harness. By the looks of the fan no one has ever been in there to service anything including that disgusting fan.
I'm definitely a convert since picking up this prius on Craigslist. Love the mpg. Can't wait to do the suspension work on it to make it a great daily car.

Thanks again to everyone for their input I greatly appreciate it
