Attached photos to see the chips for yourself.

 

Which one contains the eeprom data with mileage, pin etc? What hardware can read and write these chips?

 

1. Read eeprom 912DG128 – Xprog, UPA …

 

2. DSP3+ will do it also, carprog, x-tool as well.

I have been mainly using Xprog V5.55. This is the best source of Xprog:

And testing images below:

Connect the adapter to Xprog;

select chip (i.e Microchip 24xx128)

Click on “Read”, it will show the VIN number.

 

What about Carprog, does it read the data as the same as that of Xprog?

We select chip.

Reading the chip

Save this file.

 

So, their data has no differences.

 

Enjoy!
