Maybe it's protected :)

[Min2xx]

And how I can change km?

[hoangtu]

epprom separate read-only. I think so. do not try to write in pic lock. very high death risk dashboard.

[gogalv]

No risk, no.
All is inside the Board...
And one must raise the pins.
When will learn to correctly specify the information and photos of the DASH, then you can help ...
