WinOLS Disable/Close FAP and DPF for EDC16C34

In this instruction i will show you the guide on how to use WinOLS to disable/close FAP & DPF for EDC16C34.

 

You should find the following 8-bit hexadecimal string! 00 7F 00 00 00 00 00 00 00 00 02 01 01 00 0C 3B In this string 02 01 must be changed to 00 00 for DPF off. (You can also find only one of the 2 values) To find this search string for 01 00 0C 3B you can get 1 or 2 results

EXAMPLE :

 

You should find the following 8-bit hexadecimal string! 00 00 01 00 00 00 28 44 00 00 43 1C 00 00 43 1C In this string 01 must be changed to 00 for DPF off. (You can find it instead of 01 à 02 but the result is the same) FACT: 0- dpf off probe off 1 – dfp on probe on 2- dpf off probe on To find this search string by 00 00 28 44 00 00 43 1C 00 00 43 1C.

 

EXAMPLE :

 

Open Winols select new project and binary file, select the file and open it at opening select the VW golf damos etc. etc. su hexdump right click on Values property: 16bit (LoHi) number format: decimal and give it ok. now function search byte sequence always decimal and enter 32767 32768. obviously there are more than one sequence and the address of the dpf switch is not always in the same place. it is usually between 1 place and 3 after the sequence and it is 00256. Change 00256 to 00000 and turn off all dpt functions on edc16. If you can’t find the sequence 32767 32768 it reverses LoHi with HiLo always in 16bit decimal. 

 

 

 

These procedures are not the result of my work but have been taken from the forum and grouped and explained more clearly here to facilitate everyone’s work.
