My temperature display recently started defaulting to celsius instead degrees. I have to turn the engine off and back on and it goes back to degrees. It just started happening. It is happening about once a week. Any suggestions???

 

And all this time, we were under the impression that you need to reflash the ecu to change F -> C display.

Lot of people who took a US market RX north of the border wanted to do what you are experiencing, but one more permanent basis.

keep us informed.

i wonder how accurate these things are anyway. sometimes mine will display 98 degrees on a 85 degree day.

 

Mine did the same thing. I'd try resetting the ECU. Mine got corrected when I changed the battery (of course the ECU was reset during the change so...)

That is unusual, but unusual electrical symptoms are often a signal the battery is on it's last legs. If the battery is over 5 years old, I'd replace it. A Costco battery is only about $60 and it's an environmentally friendly thing to do in that the old battery is recycled.
