Kienzle Tachograph - 000000km problem

[pjrevs]

Guys,

I was remove Kienzle tachograpf from Atego 2005 year. Inside is 24C04 ( attached ), i was read, change mileage like every time till now...and got 000000km on display.

Now i always have 000000km on display, even if i back original file.

I was hear that have some file what i need to programm before i back original software, to reset some data inside tachograpf.

Anyone have same problem before and solution for this ?

I think if you open tachograph without special service card all data was erased
