Bit dtc and lights

[chicco]

in the meantime, take a look at these examples, I have taken an ecu vw edc15 of a 101 hp the powered tour with diagnosis connected I have taken note of the errors both in the code P-VW (five digits) I have searched in the 2d (16-bit intel in this case), and I took it to zero those areas one at a time until the memory errors appeared not pi? nothing, the only thing I have connected an external light for the light failure.from the tests I have done if the error results in recovery it is difficult to exclude the one over the light.

ok the dar? take a look and help? know.
in the meantime, thanks

ok, I've had a look but the problem ? the usual one:we have an error code, figure out how to transform it, and then find in the map....unfortunately cos? at least I only see the bits that have numbers but nothing more?....

[chicco]

if you look closely at the bits reset to 0 there are also error codes in 5 digit vw and if I remember correctly, also the Pxxxx, then the best system as I said ? have an ecu on the bench, or even better, a machine on which cause the error and then do the various tests.

[ducati83]

ok but do you have a table of codes vw?

Guys online there was a document that explained how to do it through a series of calculations and steps...should find and study a bit on that,on the contrary I think I've seen it right here on the forum.

I found this I don't know if you were talking about the same thing:

hmmm the thing ? interesting.....but the fact remains that it should be true of the known data to be able to intervene....

no I don't follow: then I address 0528CC in the upper right find myself under the table Dec. 19561,0000 then this number corresponds to an error vw, which then in turn corresponds to a code error Pxxxx?

[chicco]

exactly, if you are looking for the error code veg 19561 in the network, you'll see that it corresponds to some sensor that was not connected when I turned on the ecu tour type tair th2o or pressure coll, etc..

ok with winols I open up the search in hex 16-bit and I look for the error code without the p, but I do not corresponds to the hexadecimal number of the error vag as ever?

[chicco]

simply because? the error in P is written in a point (display in hexadecimal), and the error vag ? written in another place and see it in decimal, not ? that by converting the error in P from hex to decimal return to you the error vag, are in two blocks distiniti.

if you look closely at where you can find the value 19561 the next value ? in hex 3105 that would be P3105, pi? forward, you see the error 17564 and the value next bed in hex ? 1156 (P1156), I hope to be a p? pi? clearly, in order to intervene and eliminate the errors you have to make a p? of tests, sometimes you succeed and sometimes not.

[ducati83]

so if I find an error in the ecu, for example, P061b, you'll find? with a search in the hex a bit in the map that must be brought to zero.....but if ce n'? more than one with that value?
then I would like to be clarified: but the dtc ? a bit, or has a structure?in this second case should be constants detected in each error....or am I wrong?
thanks again.....
