Work few minutes today on this. J1 have bkgb,5v and ground but not continuity with reset pin to j1 but ok i have place to solder the reset. And have continuity between vddx1-vssx1 and vddx2-vssx2. Ground with ground and positive with positive. Try to read tomorrow with usaprog

Yes friend. But make this for learn and like check my knowledge. Thank's mate

it's a test for transfert file. i read with usaprog. i think the mileage is on line 0020 (13D908) and 0030 (13D908) someone could help me to valid this. It's appreciated friends
And if like 3500km i'm good if replace by 305705

Your calculations look good, but I suspect that will give you an error because of the checksum at the end of lines 0020 and 0030.

Looks like a simple addition checksum +1

Try 30 57 05 00 xx xx xx xx xx xx xx xx xx xx ca a9

[Berubeg]

Hello cluster. If is possible for you to give me little bit more info about checksum here or by pm. Or You have a place for read more about this. Realy appreciated.

Did you try it? Not sure if this is correct for this one, but it is used in other algorithms.

Add words, xor with ffff add 1

Original:
13d9
0800
1bd9

Xor = e426 + 1 = e427

New

3057
0500
3557Xor = caa8 + 1 = caa9

cluster i'm drive few km and this is the result for compare the checksum. it's not clear for me i'm calculate this evening!

Why in line 0040-0050-0060-0070 some value change between 2 files? in two file trip km a,trip km b and trip hours are reset to 0

Cluster all work good! Thank's for your support
