hi all .........

milege Hyundai i10 24c16 ..... Topic open to discussion
Let us understand and break this type of algorithm and compute the checksum .

dump orignal value : 86779 km
I calculate the file this way .

86779 km = 86779 x 32 = 2776928 to hex = 2A5F60 / 32 = D8F2

D8F2 = this is milage 86779 km .
------------------------------------------------------------------------------------------------------------
You changed dump l value :21600 km
I calculate the file this way .

21600 km = 21600 x 32 = 691200 to hex = A8C00 / 32 = 3600
3600 = this is milage 21600 km .

Dachbord show value 21600 OK
------------------------------------------------------------------------------------------------------------

You changed dump l value :13600 km
I calculate the file this way .

13600 km = 13600 x 32 = 435200 to hex = 6A400 / 32 = 2200
2200 = this is milage Normalment 13600 km .

Dachbord show value Error ... OK

Inevitably there is a checksum !!!!!

Your problem is about the 4th character

it should be D8F3, not D8F2

thank you hcip (https://www.digital-kaos.co.uk/forums/member.php/107817-hcip) the problemme not file

put 2205 for km value of 13600

[Team dz]

Why did you increase number 5? Can you explain to me? 2205

When we calculate 13600

13600 km = 13600 x 32 = 435200 to hex = 6A400 / 32 = 2200

************************************************** ******************

2205 = 2205 x 32 = 6A4FA to decmal = 435450 / 32 = 13607 km

5 is a checksum of 220

how to calc checksum :220

[jomberykaso]

2205 *32= 06A4FA to Dec = 435450 /32 = 13607

how to calc checksum :220


your calculation got it, but after you get the total, Shift Right to 4 (2200 shr 4 = 2200) then calculate checksum, (Visteon checksum)

checksum is the last byte

[Team dz]

Thank you again but I did not know the checksum account


Only the total for a possible test is shown, showing how it is calculated

@Team dz u know how cal checksum?

[Jardel]

When the dashboard shows more than 100,000 km, the calculations change completely. Someone to help?
