HV Battery temperature

Why are you clearing the trouble codes without reading them. The trouble codes will tell you the problem that the car is seeing.

 

Since you can figure out how to clear them you should be able to figure out how to read them with a capable scan tool then that light bulb might go off and burn brightly how do you know your battery is getting hot who told you that? Or what determine that? The energy monitor on your multifunction display when you're driving the car how fast does it change from blue to green and back to red magenta and then back to blue and then back to green and maybe back to blue and not even see the magenta because you're driving how fast does that display changing? Do you hear the fan in the right rear quarter panel running like crazy You stop at a stoplight you hear a fan behind you running on near full tilt? No then probably not an overheating problem Why would you think it was a battery overheating problem Is it warmer in the car I mean just got to be a reason we're talking about temperatures because it's hot outside You don't drive around when it's 100° out with your air conditioning on and the windows rolled up that's the air the battery fan is sucking across the battery and then blowing it out the right rear quarter.
