EDC16 - Elimiazione DTC Formula true or false?

[megamind]

Hi to all, someone's? on edc16 how to eliminate the sensors and any dtc?
For example, if I have a dtc Pxxxx displayed on the picture as I look at the map and then take it off permanently.
There is a kind of research - the identification and elimination total?

An example of car defappizzate c'? the egt2 on the fap that should not serve more? nothing
as you f? to eliminate the sensor and the relevant dtc without the use of a softwere in charge of this operation?

I found this explanation in the network, but not ? for me very clear (always true):

There is the DTC number table and DTC switch table after that in EDC16.

I know, to turn off a certain Pxxxx code, find it in the DTC number table when it appears first time in the 16-bit hex format.

Formula: (address of Pxxxx code - address of DTC number table beginning)/8. The Result will be the index number.

Then find the beginning DTC switch table which is right after the DTC number table. Switch to 8-bit view.

Formula: address of the beginning of the dtc switch table + index.

Zero address you calculated and Pxxxx code will never appear again

Here it says that c'? a table with the numbers of DTC, and another table after with the related DTC switch.
To turn off a Pxxxx code, ricecarlo in the table of numbers DTC when it appears for the first time, a 16-bit hex format.
Once you have found c'? a formula that I do not understand what to do?
Someone who has the expertise and want to share can explain this formula (translate it) and make a practical example?

Thanks

I'd like to see myself, looking forward to some expert , who can help

[leandro89]

nice discussion, but I don't understand either I the formula

[msport (exil77grande)]

not simple for no-one believe me.

[tonyteam]

true, c'? to say that the companies ir? the famous, often do not have brains that map, but the sw well-made automated in almost everything:from the removal of the dpf to the errors dtc in the dtc tables

I'm attempt to decipher the forumula, even if I have the service with the admin of the forum for personal knowledge or for some work on Sunday thinking they know not ? evil!

I open this thread because interesa also' me...

For the test I used this file ori:

The formula should be the right one, but the problem and find the three addresses of the beginning of the three tables.

The first table, and the beginning of the tabela where you have to aggire to turn off DTC we want to - you look in 8bit 2D - e' 1D06C0
The second table, and the beginning of the table of the codes of the produtore (VAG in this example, but now we don't need it) - search in the decimal 16bit
The third table and the beginning of the table P-codes and it would be at the correct address 1D9620 (see below as I have found) - search for hex in 16bit


So, first you need to find the code hex editor for the DTC that' if you are, for example P1556 imettiamo in search hex 1556 and we find it on the address 1D97A0. Now let's get it on' in the table to see where begins the block of the DTC and we find that' and' to the correct address 1D9620because above it there are only zeros.

Now we use the formula (DTC-DTC-start)/8 and we arrive at 31 a decimal that would be the DTC index -> (1D97A8-1D9620)/8=31

This means that to turn off the DTC must be put to zero the 31-bit unesimo from the beginning of the table, where are the codes to turn off the DTC.

Now comes the problem because it is difficult to find the beginning of the first table that would be that, where from the beginning we count 31-bit, and put it to zero to shut down the DTC that we want.

This table bissogna look for in 8 bits, and the decimal values in the bloco should not be above the number 20open to some.

Looking for I found the block to be 1D06C0 to 1D084F and I think, that here would be that our first, and most important of the table, where we should aggire.
Then the beginning of the table and 1D06C0 + 31 (DTC index) = 1D06DE that' has the value 2and that to disable we 0.

Paraticamente, now if there would be the erorre P1556 active, putting the value 0, the same is not verebbe reported.

Alora that' firms ? You may be right?
I wait for your comments...

I don't know if the procedure is right, you should create an error, and then try to disable it using this method.

The procedure and correct even if there are any of the constructors of the class to keep in cosiderazuone, but the problem and be able to understand the beginning of the tabbelle DTC, what is not ? easy.. it's not necessary for, and what to create a error.. and then delete it but pirima delete it and then see if it works

I think that the two things do not vary much, is if you make a mistake and then you disable this feature, or if you disable and then you create it to see if you from, are similar.
