Default E/M are reset all days (boring)

Hello,
i have a problem with the information on dashboard

when i drive my corvette, i read it in km/h
if i park the car for 1 day or more, when i go back in, the dashboard is in miles/h

it does'nt make it before, and i would like to know why ?
is there a memory relay in the dashbord ? where it is ? there is an other relay ? maybe a battery like a personnal computer for the rom ?

thank you

I would be looking into the condition of your battery as a first step.

What 8VETTE7 said...I have a Canadian spec car...When I first got the car it was constantly defaulting to KM/H when i had it set to MPH...I thought that it was because it was a Canadian spec car and that I would just have to live with it..Then I began noticing other little quirks associated with a weak battery. I replaced the battery and life was good.............

I have seen the same problem before. Once it was a weak battery and the other time it was a bad battery cable ground.

hello !
i have tried this : start engine, put in km/h , ride

stop the car, park and before turning off, put the "oil temp"

i go for 2h, came back and the km/h is still the same so ... it's good

but for me it's bad because is i do the same operation 1 week later, it goes, like you said, the mileage appears again in miles and not in km/h :'(

what do you think about that ? allways the battery ? (the battery is new from november :/)
