C36 AMG cluster please help increase kms

**juzzac** · 17th December, 2013, 12:50 PM

Hi,
I have a customers Mercedes w202 c36 cluster that has a disfigured lcd temperature display, i have tried another lcd display and it did not make any difference, i then tried swapping 93c56 into another cluster with the exact same part number with same software and hardware status, as soon as i swapped the eeprom to the good working cluster the Temp display became disfigured exactly the same as the original cluster. I soldered on the original eeprom back on the good cluster and found it to work normally, which means the customers eeprom software is corrupt.
The customers cluster has traveled 175,000kms and the donor cluster has traveled 110,000kms. can someone please help me adjust the kms in the good eeprom from 110448kms to 175,903kms, i am happy to pay for your time to help me with this.

The eeprom with 175,903kms has the markings 93c56 on it
The eeprom with 110448kms has the markings cs566 on it.
The part number of both clusters is A2025400111 and the Motometer number is 5220301300

Thanks Juz

Hi Xmodder,
Thanks for all your help, it now shows exactly 500,000kms instead of 175,000kms do you have any more ideas ?

Juzzac, I have just looked at your 175,903 bad dump. you have read it as 8 bit. It should be read 16 bit. But no problem as you are going to use the other dump which I edited and that is 16 bit. Arthur.

Thanks so much Arthur and Xmodder for all your efforts , I will test it in a few hours and let you know
also thanks for advice re reading 8/16 bit ( I'm still learning )

Hi,

Thanks.

Hi,

Sorry to refresh this old thread, but I need help. Could somebody change the 110.448km file from the first post to 82.104km - When I try it, I get only 500.000km in the Display.
I tried to count backward, but I'm doing something wrong.

I changed the damaged Display in a C36 odometer and it shows nothing. I load the 110.448km file from the first post in it, and it works, but with wrong km.

Thanks for your help.
